You can use any [XMPP-compatible software](https://xmpp.org/software) to join the XMPP messaging network.
Developers can integrate their own software with XMPP using our [published specifications](https://xmpp.org/extensions).
XMPP is the open standard for messaging and presence
----------------------------------------------------
XMPP powers emerging technologies like [IoT](https://xmpp.org/uses/internet-of-things/), [WebRTC](https://xmpp.org/uses/webrtc/), [Instant Messaging](https://xmpp.org/uses/instant-messaging/), [Online Gaming](https://xmpp.org/uses/gaming/), and [Realtime Social](https://xmpp.org/uses/social/).
No one owns XMPP. It's free and open for everyone [since 1999](https://xmpp.org/about/history/).
It's a [living standard](https://xmpp.org/about/standards-process/). Engineers actively extend and improve it.
Millions use [XMPP software](https://xmpp.org/software/) daily to connect to people and services.
Software for every platform
and libraries for every language
