Welcome – Prosody IM
Prosody is a Jabber/XMPP server written in Lua
Categories:
Prosody is a lightweight, modern XMPP communication server designed for easy setup, low resource usage, and high extensibility, serving self-hosters and organizations seeking privacy-focused messaging.
🚀 Overview
Prosody is an open-source XMPP (Extensible Messaging and Presence Protocol) server that enables real-time communication like chat, group messaging, and presence sharing. It solves the problem of reliance on proprietary, centralized messaging services by providing a self-hostable alternative that prioritizes user privacy, federation, and control over data.
It's built for system administrators, developers, organizations, families, and anyone wanting to run their own secure chat infrastructure. Development started in 2008 by Matthew Wild and the Prosody team to create an efficient, extensible XMPP server that's simple to deploy and customize, powering thousands of services worldwide.
