WebSocket
Ably’s native protocol is WebSocket-based. It offers the right balance between performance, portability, and reliability.
Automatically translate between protocols
There is rarely a one-size-fits-all protocol: different protocols serve different purposes better than others. We support multiple open protocols so you can develop in the direction that’s right for your needs.
Ably handles all the background work of ensuring interoperability at the protocol level so you can easily use multiple protocols within your application.
