Send and receive messages to connected clients.

Supabase provides a globally distributed [Realtime](https://github.com/supabase/realtime) service with the following features:

*   [Broadcast](broadcast/index.md): Send low-latency messages between clients. Perfect for real-time messaging, database changes, cursor tracking, game events, and custom notifications.
*   [Presence](presence/index.md): Track and synchronize user state across clients. Ideal for showing who's online, or active participants.
*   [Postgres Changes](postgres-changes/index.md): Listen to database changes in real-time.
