ChatKit

Designed for product teams that want to add in-app messaging, direct messages, group channels, or live chat features to their platforms, Chatkit provides the server-side architecture message persistence, user presence detection, typing indicators, read receipts, and delivery guarantees while developers focus on the interface and user experience specific to their product.

This approach dramatically accelerates time to a working messaging feature compared to building on top of raw WebSocket connections or self-managed databases.

The SDK abstracts the complexity of real-time data synchronization, handling reconnection logic, message ordering guarantees, and concurrent update conflicts in ways that are notoriously difficult to implement correctly from first principles.

Developers get clean, well-documented client libraries for JavaScript, iOS, and Android, enabling the same messaging backend to power consistent experiences across web and native applications simultaneously.

Webhook support allows development teams to trigger server-side logic when specific messaging events occur for example, sending a notification when a message goes unread for a defined period or flagging content for moderation review.

Chatkit is well-suited for marketplaces, SaaS platforms, community products, and customer support tools that need messaging as a feature rather than as their entire product.

Teams can implement basic one-to-one or group messaging in days rather than months, with built-in scalability that handles concurrent user growth without requiring infrastructure re-architecture.
