In today’s app-driven world, users expect more than just content—they expect interaction. From realtime chat and video calls to social feeds and reactions, community features have become essential in apps of all kinds. That’s exactly where Streamchat comes in.
Whether you’re building a social app, a game, a telehealth platform, or a team collaboration tool, Stream provides the tools to add in-app chat, video, and feeds—fast and at scale.
In this article, I’ll walk you through what Streamchat really is, how it works, what you can build with it, and why so many developers are choosing Stream over building Chat from scratch.
What Is Streamchat?
Streamchat is the chat and messaging solution offered by Stream—a powerful platform that provides APIs and SDKs to help developers build in-app chat, video, and activity feeds.
Instead of spending months designing and coding your own chat infrastructure, you can integrate Stream’s battle-tested tools and go live in days. Stream handles the hard parts like message delivery, scaling, infrastructure, moderation, and even UI components.
Think of it as a complete developer toolkit for community features.
Why More Apps Are Adding In-App Messaging
You’ve probably noticed that most popular apps today have a built-in messaging feature. And for good reason.
Here’s why apps in every industry are investing in realtime communication:
- User Engagement: Chat keeps users inside your app longer.
- Retention: People return more often when there are conversations happening.
- Functionality: Messaging, video, and feeds often drive the core of a product (e.g., Slack, Discord, TikTok).
- Support and Feedback: In-app chat creates faster support options.
- Monetization: Social features often lead to higher LTV and user stickiness.
If you’re building an app in 2025 and you don’t include chat or community, you might be missing a huge opportunity.
What You Can Build With Stream’s API & SDK
With Stream, you can build way more than just simple messaging. You get a flexible system to create complete social experiences, including:
Realtime Messaging
Build 1-on-1 chats, group chats, team channels, and even public chat rooms.
Video & Audio Calling
Add voice and video calling with Stream’s video SDKs—perfect for healthcare, dating, or education apps.
Activity Feeds
Stream is famous for its activity feed engine, used by apps like Dubsmash and TaskRabbit to build newsfeeds, timelines, or notifications.
Threads, Mentions, Reactions
Support advanced chat experiences like:
- @mentions
- #hashtags
- message reactions
- reply threads
- message editing and deletion
Message Moderation
Streamchat includes tools for automating moderation, including:
- Profanity filters
- Flagging messages
- Banning users
- Rate limiting
You don’t need to build these safety systems yourself.
Who Is Streamchat For? (Use Cases)
Stream is trusted by developers, building everything from indie apps to billion-user platforms. Here’s where it really shines:
Social Media Apps
Think of features like DMs, comments, or live chat. Stream makes it simple to recreate these without building your own backend.
Gaming
Enable chat between players, voice rooms for multiplayer, or community forums—all without reinventing the wheel.
Marketplaces
Buyers and sellers can message each other securely inside the app, like on Etsy or Upwork.
Team Collaboration Tools
If you’re building a Slack-style tool or a productivity platform, Stream can handle your chat stack.
Telehealth & EdTech
Add HIPAA-compliant chat or video for doctor-patient communication or tutor-student sessions.
Streamchat vs. Building From Scratch
Here’s the honest truth: building chat infrastructure is hard. You’ll need to handle:
- WebSocket connections
- Offline sync
- Data storage
- Scalability
- Load balancing
- Moderation
- UI components
Unless chat is the core of your business, it usually makes more sense to use a provider like Stream.
Streamchat Pricing Model
Stream offers several pricing tiers, including:
- Free tier – great for testing or early MVPs.
- Startup plan – affordable and scalable as your users grow.
- Enterprise plans – for apps with millions of users and advanced compliance needs.
The platform charges based on MAUs (Monthly Active Users) and message volume. You can find full pricing on their official page, but the best part is you only pay as you grow.
Developer-Friendly Tools and Documentation
One thing that makes Streamchat stand out is its amazing developer experience.
You get:
- SDKs for React, Flutter, Swift, Kotlin, React Native, and more.
- Easy-to-use REST APIs and WebSocket support.
- Prebuilt UI components and message lists.
