6 Best Free and Open Source XMPP Servers

XMPP (also known as Jabber) is an open and free alternative to commercial messaging and chat providers. Set it up for your company, organisation, or just your family and friends. You are in control, and your communication is private to you. Supporting a wide range of client software for desktop and mobile platforms, you can chat from any device.

You can set up your own XMPP service on your server (dedicated, VPS, etc.) or on a box on your local network, to serve your home or office. Either way you can use it to converse with anyone else on the Jabber network, including people using Google Talk, probably the largest Jabber service on the network.

XMPP was designed for real-time communication, which powers a wide range of applications including instant messaging, presence, media negotiation, whiteboarding, collaboration, lightweight middleware, content syndication, EDI, RPC and more.
