About Ably
Ably is a realtime messaging platform for chat, collaboration and live data. It handles delivery, message ordering and failover so developers do not have to run that layer themselves.
What it does
Ably moves messages between devices and servers in realtime. Developers use its publish and subscribe APIs for live updates, chat features for rooms and messages, and shared state that syncs across users. The platform also offers an AI transport layer for keeping agent sessions in sync across several devices.

Pricing and good to know
