CollabKit

CollabKit is a developer SDK that enables product teams to embed real-time commenting, mentions, and collaboration features directly into their web applications. It provides pre-built React components and a backend infrastructure so developers can ship collaborative experiences without building from scratch. CollabKit handles the complexity of real-time sync, notifications, and user identity so teams can focus on their core product.

• Pre-built React Components — Drop in ready-made UI components like comment threads, popovers, and inboxes with minimal configuration.
• Real-time Sync — All comments and activity update instantly across users using CollabKit's managed backend infrastructure.
• Mentions & Notifications — Built-in @mention support and notification system to keep collaborators informed of relevant activity.
• Customizable Theming — Style components to match your product's design system using CSS variables and theming APIs.
• User Identity Integration — Bring your own authentication; CollabKit integrates with your existing user system to attribute comments correctly.
• Inbox & Activity Feed — Provide users with a centralized view of all their unread comments and activity across the application.
• Easy Setup — Install via npm, initialize with your API key, and wrap your app with the CollabKit provider to get started quickly.
• Headless Mode — Use CollabKit's data layer without the default UI for fully custom collaboration experiences.
