CometChat
CometChat · Voice & Language · Chatbot
CometChat is an in-app communication platform that lets developers add real-time chat, voice and video calling, and AI-powered agents to web and mobile apps without building the infrastructure from scratch. It ships as SDKs, APIs, and prebuilt UI Kits, plus a no-code widget builder, so teams can go from a blank screen to a working messaging layer in days. The platform also bundles moderation, notifications, analytics, and compliance tooling. That last part matters. It's why CometChat is aimed at products where conversation between users is the core feature rather than a side add-on.
About CometChat
What Is CometChat
CometChat is a developer platform for user-to-user messaging, calling, and AI agents inside your own app. Instead of stitching together a chat server, a push notification service, a moderation layer, and a video stack, you integrate one vendor and toggle the pieces you need. The company says its infrastructure powers 113,000+ apps and handles 7M+ messages a day across 163 countries, with a claimed 99.999% uptime SLA. That's a lot of traffic. And it's the kind of scale most teams can't build alone.
The main draw is speed. You get production-ready chat components and open-source SDKs. You can also start with a no-code widget if your team doesn't want to write the front end. For teams shipping an AI assistant, the separate agent platform adds chat UI, guardrails, citations, retries, and analytics around whatever model or agent you already run.
The catch is scale and cost. The free Build plan caps you at 100 monthly users. Pricing above that tier is quoted rather than listed, so you'll need a sales conversation before you know real numbers. It's also a heavier tool than a solo developer needs. If you just want a simple comment box, most of the platform goes unused. So who is it for? Mostly teams where chat is the product, not an afterthought.
Getting Started
- Sign up at app.cometchat.com and create an app to get your App ID, region, and auth key.
- Install the SDK for your stack (React, React Native, Flutter, iOS, Android, and more) or drop in the no-code widget builder.
- Add the UI Kit components to your app and map them to your own users and login flow.
- Turn on the features you want in the dashboard, such as moderation, notifications, or multi-tenancy.
- Test with the sandbox users provided, then move to a paid plan before you go live with real traffic.

Key features
Real-Time User Messaging
CometChat's in-app chat SDK covers the everyday cases: 1:1 conversations, group chats up to 50,000 members, and broadcast messaging. You get typing indicators, read and delivered receipts, quoted replies, reactions, threads, and search. Rich media includes images, files up to 100MB, documents, and voice notes. That covers most apps. Most teams can ship messaging without writing their own protocol.
Voice and Video Calling
The calling product adds 1:1 and group voice and video calls with screen sharing, presentation mode, recording, and transcription. Calls run over the same edge network as chat. The company lists end-to-end encryption alongside HIPAA, GDPR, SOC 2, PIPEDA, and ISO compliance. For apps where a call is a natural extension of a conversation, this saves standing up a separate real-time media vendor.
AI Agent Platform
Beyond plain chat, CometChat offers a full-stack agent platform. You can build an agent with natural language, or bring your own and plug it in through the agent dock to inherit chat UI, orchestration hooks, and delivery. The agent-ready interface supports streaming replies with thinking states, inline citations, retry and stop controls, and interactive UI actions like buttons and forms. It's a practical way to wrap an existing model in a usable product surface. No glue code required.
Prebuilt UI Kits and SDKs
Open-source chat UI Kit components and SDKs span the common frameworks, so you're not rebuilding message lists and input boxes by hand. You pick an integration path. There's a no-code widget builder for quick launches, UI Kits for low-code customization, or raw SDKs and APIs for a fully bespoke build. Every path runs on the same real-time messaging API underneath. Teams can start with one path and move to another as requirements grow.
Moderation and Guardrails
Content safety runs through three options you can mix. There's built-in contextual moderation from CometChat AI with pattern and keyword filters. There's OpenAI's moderation models with dashboard control and your own API key. And there's your own moderation service via secure endpoints. Guardrails and fallback logic protect agent conversations too, which matters once users can prompt an assistant directly.
Analytics, Notifications, and Multi-Tenancy
Chat is only useful if people come back to it and if you can see what's happening. CometChat includes native, email, and SMS notifications with customizable templates. It also ships analytics that track usage rates, reply patterns, and engagement. Multi-tenancy keeps separate conversations and users isolated across platforms. Advanced search and message translation round out the feature set.
Pros and cons
Pros
- Ships chat, calls, and AI agents from one vendor, cutting the number of integrations you maintain.
- No-code, low-code, and full-code paths mean teams can start fast and customize later, which is a real advantage when the first version of a product needs to ship before anyone knows how it will evolve.
- Compliance coverage (HIPAA, GDPR, SOC 2, ISO, PIPEDA) removes a big blocker for health, finance, or any other app that has to prove its data handling meets an outside standard before launch.
- Moderation and analytics come built in rather than as paid extras.
- Global edge network with a 99.999% uptime claim supports apps in many regions.
Cons
- The free Build plan stops at 100 monthly users, so any real product pays quickly.
- Paid tiers are quoted on request, which makes budgeting hard before you talk to sales.
- It's overkill for apps that only need a simple comment or notification feed.
- You're tied to CometChat's SDKs and UI, so migrating away later takes real work.
