CometChat React UI Kit
CometChat React UI Kit is a prebuilt React chat component library for adding in-app messaging, with optional voice and video calling. It supports React.js, Next.js, React Router, and Astro and is designed to reduce the amount of setup and state handling needed to launch chat UI.
Overview
CometChat React UI Kit is a prebuilt set of React chat components for building in-app chat experiences, with optional voice and video calling. It is positioned for teams that want to add real-time chat without manually wiring SDK setup, state management, and message handling from scratch.
The kit supports React.js, Next.js, React Router, and Astro, and the documentation says it is SSR-safe and compatible with Next.js App Router. Setup is designed around installing the package, connecting a CometChat app with dashboard credentials, and assembling selected components into the layout your product needs.
Key capabilities
Composable, extensible UI
Use compound components and a plugin system to compose the parts you need and customize how messages render, including custom bubble types.
Plugin-rendered message bubbles
Start with built-in support for text, image, video, audio, polls, stickers, and custom message types, with shared chat chrome handled automatically.
Optional calling support
Add voice and video calling as an optional part of the integration through the CometChat calls package.
Framework and SSR support
Work across React.js, Next.js, React Router, and Astro, with SSR-safe behavior and no browser-only APIs at module scope.
Chat UI building blocks
Use built-in theming, localization, unread counts, presence, read receipts, threaded messages, reactions, and message composer features.
Common use cases
Ship in-app chat faster
Add a chat interface to a React product without building the messaging UI, state handling, and real-time updates from the ground up.
Customize a chat experience
Use the component set to design a chat layout that fits your app, then adjust styling and composition as requirements change.
Integrate across React-based stacks
Build a framework-compatible implementation for apps using Next.js, React Router, or Astro while keeping the integration path consistent.
Support full-featured messaging
Enable richer messaging workflows with conversations, messages, users, threading, unread counts, and reactions in one UI kit.
Extend chat into calling
Add optional voice and video calling to an existing chat experience when your product needs communication beyond text.
