The goal of this project is to deliver on XMPP's original vision: create a modern open platform for federated instant messaging with an emphasis on mobile communication. Instant messengers are still a bunch of incompatible walled gardens, similar to what AoL of the late 1990s was to the open Internet. Unfortunately, XMPP never delivered on this promise. The promise of XMPP was to deliver federated instant messaging: anyone would be able to spin up an IM server capable of exchanging messages with any other XMPP server in the world. Follow instructions to install and run or use one of the cloud services below. This is beta-quality software: feature-complete and stable but probably with a few bugs or missing features. On the surface, it's a lot like open source WhatsApp or Telegram. Wire transport is JSON over websocket (long polling is also available) for custom bindings, or protobuf with gRPC. Backend in pure Go (license GPL 3.0), client-side binding in Java, Javascript, and Swift, as well as gRPC client support for C++, C#, Go, Java, Node, PHP, Python, Ruby, Objective-C, etc.
