SDK is a software development kit that bundles client libraries, UI pieces and helpers so you can integrate chat, community and live features with less custom code than calling the API directly.

<h2>What Is an SDK?</h2><p>A software development kit (SDK) is a collection of tools that enable developers to build more quickly for a particular platform or service without having to reinvent every building block. In practice, an SDK often consists of one or more client libraries plus documentation and example code, and sometimes debuggers or configuration tools—all optimised for a specific OS, framework, or API.</p><p>While an API documents what you can call and how the request/response should look, the SDK documents how you should use that API in a given language. It abstracts away much of the HTTP plumbing, request authentication boilerplate and data management so developers can write “normal” code rather than mixing-and-matching raw requests.</p><h2>How do they work in chat and live experiences?</h2><p>In in-app chat and live experience products, SDKs usually do more than just wrap API calls. A typical chat SDK might provide:</p><ul><li>A platform-specific client library (for example, for iOS, Android or JavaScript).</li><li>Pre-built UI components such as a message list, composer, reactions, threads and typing indicators.</li><li>Helpers for state management, theming and real-time updates.</li></ul><h2>Difference between SDK and API, iFrame and WebView</h2><p>An SDK is just one of a handful of paths to integration that a team can take:</p><ul><li><a target="_blank" rel="noopener noreferrer" href="https://watchers.io/glossary/api">API</a>—the low-level contract: URLs, methods, payloads, auth.

API is an application programming interface that lets your backend, CRM or automation tools control rooms, community chat and live experiences programmatically.

<h2>What Is an API?</h2><p>An API (Application Programming Interface) is a contract enabling one application to communicate with another in a predictable manner. In practice, it is a collection of rules, endpoints and data formats which specify a means for calling into a system and what one can expect in response.<br>In place of clicking buttons in a UI, another service calls an API: making a call out over the network (most likely HTTP), the platform validates the request within its business logic and returns structured data, typically as JSON. APIs have become the primary method through which modern products share data and invoke actions across one another.</p><h2>APIs in Social and Live Products</h2><p>In social or live content products, APIs usually sit on the backend as the under-the-hood layer that connects real-time features to the rest of the stack. They let you control chat and other live surfaces programmatically, plug moderation into internal tools, control access and feed engagement data into analytics or marketing systems, instead of handling everything only through a chat UI.</p><h2>APIs and Webhooks</h2><p>APIs are often used together with other integration tools.<br>API. The low-level contract: URLs, methods, payloads and auth. You can interface it from any backend system, job or integration platform capable of making HTTP requests.</p><p>Webhooks. Whenever something happens (for example, a live session starts or a user reaches a milestone), instead of you polling the API for updates, the platform sends the events to your URL.<br>Together, they allow you to manage what goes on in your real-time features (via API calls) and respond to it in your own product (via events and automations) for social features such as <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/glossary/community-chat">community chat</a>, without having to rebuild the engagement layer from scratch.</p><p>Watchers have an <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/catalogue-api">API catalogue</a> that allows clients to connect many tools and features with clients' existing systems and provide seamless and the fastest experiences for users. For instance, an API for marketing offers that can be sent to needed cohorts, or a ban API that allows you to synchronise the moderation system in a chat with the main platform user profiles.</p>

WebView is a browser surface embedded in a native app to load web pages like dashboards, help centres, or community chats without rebuilding them in native UI.

WebView

<h2>What Is a WebView?</h2><p>Webview is the browser surface embedded in a native app. Instead of sending users to Chrome or Safari, the app embeds a window to load and display web pages without users leaving the app shell.</p><p>A webview lets product teams containerise and reuse their web experiences on iOS, Android or desktop. Point the webview at a URL and show that page in your app as if it were another native screen. Content, layouts and logic stay on the web side, while navigation, login, and push notifications remain in the native app.</p><p>On the web, you typically embed external content using an <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/glossary/iframe">iframe</a>. This concept is replicated in a native app using a webview.</p><h2>How Product Teams Use WebViews</h2><p>Webviews are used in many rapidly evolving apps or those relying on web tooling:</p><p>* Reuse of existing features. Both the site and sections of the mobile app (e.g. account pages, dashboards or help centre) run on the same web codebase.</p><p>* Faster updates. Marketing pages, support content or community sections can be changed on the server without needing to ship a new build of the app.</p><p>* Experiments and rollouts. Teams can A/B test web layouts or copy, while the app only hosts a container.</p><h2>WebView, Iframe and Native UI</h2><p>Webview and iframe address the same basic problem—loading a web document by URL—but in different environments:</p><p>* An iframe resides inside a web page in your browser.</p><p>* A webview resides within a native app and injects a browser into that app.</p><p>* Pure native UI screen: This is the specific platform UI component; it does not render any HTML.</p><p>In many products, the same social layer appears as an iframe on the website and as a webview in the mobile app. Users see one consistent <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/glossary/community-chat">community chat</a> or <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/glossary/watch-party">watch party</a> experience, even though the host environment is different.</p>

iFrame is an HTML element that loads one web page inside another. It is often used to embed tools like community chat, watch parties, or dashboards without rebuilding them in the main frontend.

iFrame

<h2>What is an iFrame?</h2><p>An iframe (inline frame) is an HTML element that enables you to embed another web page within your current one. On screen, it is just a block or Panel type component, but in that block, a whole independent document is loaded with its own URL, scripts, cookies and layout.</p><p>Product teams use an iframe to embed ready-made tools and content: community chat, watch parties, dashboards, payment forms or help centres. Instead of having to re-implement all of this in their own frontend, they load a complete experience into a frame.</p><p>A similar concept appears in native mobile apps, where a <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/glossary/webview">webview</a> is an embedded browser view within the app, not the page.</p><h2>Iframe vs Native or SDK Integration</h2><p>Iframe embed. You embed an iframe with a specific URL. The UI, logic and updates are owned by the provider. You have easy deployment, clear separation and fewer chances of CSS or JavaScript conflicts. You use APIs to provide additional tools, linkage with CRM, and you use webhook events to get the needed data.&nbsp;</p><p>Native / SDK integration. You use APIs and SDKs and render everything yourself with your own components. This gives full control over UX, accessibility, routing and data flows but requires much more design and engineering work.</p><h2>Chat, Communities and Live Experiences Iframes</h2><p>For engagement use cases, this is typically wrapped in an iframe:</p><p>* a <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/glossary/community-chat">community chat</a> alongside live video, scores or a trading screen;<br>* a <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/glossary/watch-party">watch party</a> panel mashup of chat, reactions and polls;<br>* a surface that provides support or assistance in a particular product area.</p><p>In this setup, the chat solution inside the iframe takes care of the chat UI, real-time connections, translations and <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/moderation">moderation tools</a>. The host app handles navigation, authentication, permissions and analytics.</p><p>A solution like Watchers can either be integrated as an iframe in the web app or as a webview surface in mobile apps. The iframe option enables teams to quickly add community chat and live engagement, experiment with user response, and adopt new releases without syncing code changes across multiple platforms.</p>

Embedded chat is a chat interface placed directly on a page or screen so users can follow the content and the conversation side by side in the same view.

Embedded Chat

<h2>What Is Embedded Chat?</h2><p>Embedded chat refers to a chat box that is placed directly on a webpage or on a screen in an application. The user gets to view the content as well as the chat in one single window, without the need to open a different application or a pop-up window. The chat can be placed at the bottom of a video, next to a dashboard, inside a help page, or in any other fixed area of the layout.</p><p>Unlike a separate messenger, embedded chat looks and feels exactly the same as the rest of the page, including the layout and design, and it stays tied to the context of what the user is looking at.</p><h2>Embedded Chat vs Other Chat Formats</h2><p>In the case of a messenger or a floating widget, the chat window usually appears on top of the content the user is looking at. If the user opens a pop-up that covers the page, or switches to Discord or Telegram, part of their focus moves away from the product.</p><p>With embedded chat, the user can read, watch or work and, at the same time, follow the chat. The chat stays attached to the page or object the user is working with.<br>Embedded chat is a specific way to place <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/glossary/in-app-chat">in-app chat</a>. In-app chat describes messaging inside the product in general, while embedded chat describes a chat area that is fixed in the layout next to a particular piece of content, instead of appearing as a separate screen or a floating bubble.</p><h2>Typical Uses of Embedded Chat</h2><p>Product developers typically use embedded chat when they want the conversation to stay close to what is on the screen. Common examples include:</p><ul><li>chat next to a live stream, a webinar or a sports event;</li><li>chat on a help centre or documentation page;</li><li>chat inside a product dashboard or internal tool, when the user wants to discuss a report, a customer or a ticket directly on the page for that object.</li></ul><p>Read more <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/post/perfect-UX-criteria-watchers">about ways to implement chat in your platform without affecting your UX and UI</a></p>

Metrics represent the count of unique users who engage with a digital product or service within a specific timeframe. These metrics are the primary way to quantify the reach, engagement, and recurring usage of an application.

Active User Metrics (HAU, DAU, WAU, MAU)

<p>Metrics represent the count of unique users who engage with a digital product or service within a specific timeframe. These metrics are the primary way to quantify the reach, engagement, and recurring usage of an application.</p><h2>The Temporal Hierarchy</h2><p>The power of these metrics lies in their ability to capture usage behaviour across different periods. Every metric is calculated as the count of distinct user IDs that have triggered a predefined event within the following time frames:</p><figure class="table" style="width:100%;"><table class="ck-table-resized"><colgroup><col style="width:15.01%;"><col style="width:24.23%;"><col style="width:60.76%;"></colgroup><tbody><tr><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>Metric</span></div></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>Time Window</span></div></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>Typical Use Case</span></div></td></tr><tr><td><strong>HAU</strong></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>1 Hour</span></div></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>High-frequency apps (e.g., messaging, trading, live gaming).</span></div></td></tr><tr><td><strong>DAU</strong></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>24 Hours</span></div></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>Standard consumer apps, social media, productivity tools.</span></div></td></tr><tr><td><strong>WAU</strong></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>7 Days</span></div></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>Professional software, weekly utility apps.</span></div></td></tr><tr><td><strong>MAU</strong></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>30 Days</span></div></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>E-commerce, subscription services, low-frequency tools.</span></div></td></tr></tbody></table></figure><h2>Critical Technical Considerations</h2><p><strong>1. Defining the event to count</strong></p><p>A common pitfall in interpreting these metrics is uncertainty. Activeness is not a universal constant. Organisations define an active user based on their specific goals:</p><ul><li>Minimalist definition: A user who simply opens the application or faces a landing page.</li><li>Substantive definition: A user who performs a valuable action, like creating a post, completing a transaction, or watching a video.</li><li>Result: Comparing the active users of two different platforms is only valid if both entities define active users in the same way.</li></ul><p><strong>2. Unique user duplicates clean up</strong></p><p>The unique aspect is a critical technical constraint. These metrics must be cleaned up of duplicates. If a user logs in five times a day, they still have to be counted as one DAU. Systems typically handle this by tracking unique identifiers, like UserID, device ID, or hashed email, within the database logs for the specified query range.</p><p><strong>3. Meaningful Insights: The Ratio Analysis</strong></p><p>Analysts use these metrics to derive behavioural trends:</p><ul><li><strong>Stickiness</strong> (also known as<a target="_blank" rel="noopener noreferrer" href="https://watchers.io/growth"> engagement rate)</a>: It is calculated as MAUDAU​. This represents the percentage of monthly users who return to the product on any given day. A higher ratio indicates that the product has successfully woven itself into the user's daily habits.</li><li><strong>Retention</strong> velocity: By comparing WAU to MAU, it is possible to estimate how frequently users fall out of the active user base, helping to identify potential churn issues.</li></ul><p><strong>Why Context Matters</strong></p><p>These metrics are &nbsp;dependent on the natural frequency of the product. An application designed for filing taxes has a high MAU but a naturally low DAU. Conversely, a news aggregator would be considered failing if its DAU was not significantly higher than its MAU.</p>

In-app chat is a messaging feature inside an app or website that lets users talk to each other or the brand without leaving the product.

In-App Chat

<h2>What Is In-App Chat?</h2><p>In-app chat is a chat feature that works inside an app or website. A user can send public or private messages without opening another app. They can have a one-on-one chat, a group chat, <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/community-chats">a community chat</a>, or talk directly to the company. Also, in-app chat can be opened to provide technical support or to allow users to talk to AI assistants.</p><p>In-app chat differs from external messenger or SMS because it relates to the user’s account and the user’s activity. The chat occurs in the same app where the user is watching, playing, or shopping.</p><h2>In-App Chat vs. External Messengers</h2><p>Some apps begin by integrating the chat via external apps such as Discord, Telegram, or WhatsApp. However, when the chat is integrated via external apps, the app and the chat occur in two different places. If the user wants to use the chat, the experience in the app will be interrupted. The user’s focus will be divided, and the app will have only a limited view of the user’s activity in the chat.</p><p>With in-app chat, the user’s experience occurs in the same place as the chat. The user’s experience will not be interrupted, and the social aspect occurs in the same place.</p><p><strong>Why Product Teams Add In-App Chat</strong></p><p>Retention and Loyalty. Users tend to stick around longer and be more loyal when they can chat inside the app.<br>Contextual Interaction. Users can chat about what they are interacting with inside the app, like beside a video, near the match center, or next to the trading screen.</p><p>Ownership of Social Graph. Messages can link to users, which helps identify highly active users, early signs of churn, or trending topics.</p><p>Reduced Friction for Support and Sales. Support can be provided inside the app, like during checkout or complex flows, without needing emails or phone calls.</p><h2>Features and Implementation</h2><p>To be successful, an in-app chat system should be more than just a text box. Effective implementation includes:</p><ul><li><strong>Real-time Synchronisation: </strong>Low-latency delivery of messages using protocols like WebSockets is critical for live interactions.</li><li><strong>Presence Indicators: </strong>Knowing who is online or typing enhances the feeling of a live community.</li><li><strong>Rich Media Support:</strong> The ability to share images, or deep-links directly within the chat helps keep the conversation relevant to the in-app activity.</li><li><a target="_blank" rel="noopener noreferrer" href="https://watchers.io/moderation"><strong>Moderation Tools:</strong></a> Automated filters, reporting features, and blocking capabilities are essential for maintaining a healthy environment in public or group chats.</li><li><strong>Engagement Hooks:</strong> Features like threaded replies, reactions and emojis, and polls help keep the conversation flowing without requiring long-form text entry.</li><li><strong>Persistence &amp; Sync:</strong> Ensuring chat history persists across multiple devices so the user’s conversation never disappears.</li></ul><p>In-app chat can be developed further into in-app social networks with local influencer actions, leaderboards, live-streaming, and many more other features that make just talks more reliable and relevant for the main product or service.&nbsp;<br><br>&nbsp;</p>

A digital event centred around the simultaneous viewing of media, such as a film, television show, or sports, by a group of people.

Watch Party

<p>A digital event centred around the simultaneous viewing of media, such as a film, television show, or sports, by a group of people.</p><p>Traditionally, a watch party refers to individuals gathering in a single physical location to view content together. In the digital age, the term has evolved to describe virtual gatherings where geographically dispersed participants synchronise the playback of media content via the internet. Watch parties started to spread during the pandemic when people could participate offline in activities and meet, so the idea of a digital watch party became an obvious solution. However, when the pandemic ended, people continued to watch content together at watch parties because they found it convenient and time-saving: they didn't need to spend time going somewhere and organising events.</p><p>There is an arguable question <strong>whether we can call any live stream a watch party</strong>: on the one hand, people gather together online, watch and discuss content together. At the same time, the live stream has a host, initiator of the event, who manages content so it is a bit closer to being considered as a traditional TV show. Watch parties are often characterised by the same playback for all participants, while live streaming can be watched differently by participants, and the content which is streamed by a host is usually online content.</p><p>A watch party can be organised not just through specific tools like a browser extension or app, but also through <strong>the synchronised start and finish of the content screening</strong>. In this case, a watch party is close to a film screening at online festivals, for example. What is important for such a watch party is a place for communication and interaction for users, like <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/community-chats">a public community chat</a> linked to the video player. Within huge players in the video industry, Hulu is popular for their watch parties and opportunities for users to interact with each other while watching.&nbsp;</p><h2>Key Characteristics</h2><p><strong>Synchronised Playback </strong>ensures that all participants view the same frame of content at the same time.</p><p><strong>Integrated Communication: </strong>Digital watch parties typically include built-in features such as text chat, <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/live-streaming">voice and video chat or additional stream</a>, allowing participants to react and discuss the content in real-time.</p><p><strong>Social Connectivity: </strong>These sessions are designed to replicate the communal experience of traditional co-viewing, <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/post/engagement-tools-for-video-platforms">enabling social interaction</a> around media even when participants are not in the same physical space.</p><p><a target="_blank" rel="noopener noreferrer" href="https://watchers.io/post/engagement-tools-for-video-platforms">Read more about the way to engage viewers while watching</a></p>

Chat moderation is the systematic process of monitoring real-time digital communication to ensure it remains safe, inclusive, and legally compliant. By combining automated AI tools with manual review, chat owner can protect both brand reputation and chat participants.

Chat Moderation

<h2>What Is Chat Moderation?</h2><p>It is the systematic process of monitoring and managing real-time communication<a target="_blank" rel="noopener noreferrer" href="https://watchers.io/glossary/community-chat"> in digital chat.</a> It ensures that the digital space remains safe, inclusive, and compliant with community guidelines and policies. Chat moderation can be implemented across various levels—by participants of a chat and by chat owners and administrators.&nbsp;</p><h2>Mechanics and Types</h2><p>Moderation can be performed as pre-moderation or parallel moderation (similar to post-moderation). In pre-moderation, content is verified before it is published. With parallel moderation, content is checked immediately after it goes live.</p><p>Moderation can be automated, manual, or a hybrid of both. Automated moderation typically utilises AI-powered tools, block filters, and stop-lists. Manual moderation involves real-time review by human moderators. <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/moderation">Best practices suggest </a>combining both methods for the best results.</p><p>Depending on who is responsible for the process, moderation can be community-driven or owner-driven. In the former, the community itself manages the content. In the latter, the platform owner or staff handles moderation; however, in this scenario, users can still send reports or "hide" specific users to customise their own experience.</p><h2>The Reasons Why Chats Need Moderation&nbsp;</h2><p><strong>Safety:</strong> Preventing harassment, cyberbullying, and hate speech. Effective moderation ensures a safer environment for every group and participant visiting the chat.</p><p><strong>Brand Protection:</strong> Ensuring the conversation doesn’t turn toxic, which could drive away users or advertisers.</p><p><strong>Compliance: </strong>Meeting legal requirements regarding data privacy and online safety. Since different countries have various policies to protect users and companies, chat moderation must comply with <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/trust-center">all relevant regulations.</a></p><h2>Common Chat Moderation Actions and Tools</h2><p><strong>Filtering: </strong>Automatically blocking specific words, phrases, or links. Usually built on stop lists. &nbsp;</p><p><strong>Shadowbanning: </strong>Permitting a user to post without their messages being visible to others. Separate messages or all messages from a particular user can be shadowbanned.</p><p><strong>Muting/Banning:</strong> Temporary or permanent removal of a user’s ability to participate in a chat. It is important to notify users about the reason for blocking and the ban duration.</p><p><strong>Personal data masking:</strong> It protects user data from being visible not just in a chat but also on the admin panel.&nbsp;</p>

Community chat is a real-time in-app conversation channel where many users discuss shared content or topics, distinct from private group chats and support chats.

Community Chat

<h2>What is Community Chat?</h2><p><a target="_blank" rel="noopener noreferrer" href="https://watchers.io/community-chats">Community chat</a> is a live social tool which allows users to interact with one another in real time. It is different from other chat experiences, like a traditional private messenger, in that it is intended to support large-scale, public, or semi-public interaction between users who share a common interest in the content they are consuming.</p><h2>Community Chat vs. Group Chat &amp; Live Support</h2><p>There are many types of chat interfaces, which can be difficult to tell apart, but they have different technical and functional requirements.<br><strong>Group Chat / Messenger:</strong> This is used for private communication between people who, in most cases, already know one another. It is not suitable to handle “burst” traffic, and aim for another goal—private communication, without increasing the number of participants.<br><strong>Live Support Chat: </strong>This is used for one-to-one communication between a user and a brand representative. Its primary function is to solve technical issues, not to be social or emotional.<br><strong>Community Chat:</strong> This is used for many-to-many communication, supporting thousands of users concurrently, with very high message rates, measured in thousands of messages per second. The goal is build an engaging space where participants can exchange emotions, ideas, expertise, or opinions. Community chats can suit a political party website or a football club app, so any platform that gathers people with similar interests.</p><h2>How It Works Inside the Product</h2><p>In a sports app, it may activate only during a live game and serve as a place for fan chat. In a fintech app, it may attach to specific trading pairs and enable sharing. The advantage of embedded chat over external solutions like Discord or Telegram is that it keeps the user’s focus on your brand. If users leave your app to talk about your brand elsewhere, you lose both their time and their data. Community chat differs from forums: forums are something stable and slow, people are not engaged together, they share their opinion but do not participate in a live discussion.&nbsp;</p><h2>Key Community Chat Features</h2><p>To take a simple text box and turn it into an energetic environment that gets users talking and sharing, several core features and opportunities are necessary:</p><p><strong>Scalability</strong>: The infrastructure needs to support a suitable number of users. A specific number depends on the volume of your audience.<br><strong>Moderation</strong>: Community chats use <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/engagement-and-marketing-widgets">advanced multiple moderation tools </a>to prevent hate speech, spam, and scams. Personal data has to be kept safe. Any platform that provides community chats has to follow the policies of the country of operation. For the EU, it is the DSA—Digital Services Act.<br><strong>Engagement Widgets</strong>: To avoid your users getting bored, it is better to give them entertaining bits and bobs, like polls, quizzes, and stickers. Also, you can boost your main business there: for instance, publish marketing offers, and build a bridge between talk and action.&nbsp;<br><strong>Translation</strong>: Breaking language barriers by enabling a global audience to speak different languages within one single chat room is important not for all countries, but for some markets.<br><strong>Gamification</strong>: Rewarding highly engaged users with exclusive and unique badges and achievements.</p><h2>The Business Impact: Beyond Just Talking</h2><p>For product teams, the implementation of community chats is a strategic step to solve various business questions.</p><p><strong>Retention and Session Time:</strong> Connection is a strong retention driver. Social features can lead to a 10% to 50% increase in session time as users stay to see replies and reactions.</p><p><strong>First-Party Data:</strong> By owning the conversation, brands can analyse <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/post/semantic-and-sentiment-analysis-what-are-the-best-sources-of-consumers-thoughts">the sentiment and intent of the audience,</a> allowing for a deep understanding of what users love or dislike. These insights can be tracked in real time and provide much information for business growth and product improvement.</p><p><strong>Safe Environment:</strong> With multi-layer moderation, brands can ensure the social space remains a safe extension of their identity and increase user lifetime value (LTV) and help users feel safe in a trusted space.</p><h2>Implementing Community Chats</h2><p>A real-time community chat can be implemented in-house by the business’s development team or with an <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/post/best-in-app-chat-solutions">external provider</a>. Community chat is usually implemented with SDK, webview, API, or iFrame, and the choice depends on the business’s goals and requirements.</p><p><a target="_blank" rel="noopener noreferrer" href="https://watchers.io/post/buy-or-build">Learn more</a> about the difference between building community chats in-house or with a solution provider.</p>

An in-app community is a social layer inside a product where users interact with each other around content and features without leaving the app.

In-App Community

<h2>What is In-App Community?</h2><p>An in-app community forms on a social platform within an application or website. This social layer can include a forum, chat, or other digital environment for user interaction without leaving the host platform. Unlike social media groups on platforms like Discord or Telegram, an in-app community exists and interacts within the application itself.</p><p>Instead of being a silent app where users passively consume content or services, the application becomes a digital hub where users are active participants, and the app or website gains its own internal social network.</p><h2><span style="font-size:18px;">In-App Community vs. External Platforms (Discord, Telegram, X)</span></h2><p>Traditionally, many businesses try to create a community by sending users to social media, because building it inside the app was impossible.
