slixmpp
Slixmpp is an elegant Python library for XMPP (aka Jabber).
Decision gist · record as of 2026-08-14
Yes, if you need async XMPP support in Python 3.11+. Slixmpp is actively maintained, MIT-licensed, has no known vulnerabilities, and offers prebuilt wheels for common platforms, reducing install friction. The medium friction is manageable for most deployments. Install it if you're building real-time messaging, presence, or chat features over XMPP and want a modern async-first library.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.11 or later; building from source requires cargo if prebuilt wheels are unavailable for your platform.
- Medium install friction due to Rust-based extension modules; prebuilt wheels are available for Python 3.11–3.14 on common platforms (manylinux, musllinux, aarch64, x86_64), but building from source requires cargo if wheels are unavailable.
- Three runtime dependencies (aiodns, pyasn1, pyasn1-modules) add modest overhead.

What it is and what it does
Slixmpp is a modern async XMPP library for Python 3.11+ that replaces the older SleekXMPP by removing all threading and rewriting the low-level socket handling, timers, and event dispatch to work with asyncio. It lets you build XMPP clients and components that send and receive instant messages, presence updates, and other real-time data over the XMPP protocol.
The library uses Rust-compiled extension modules for performance-critical sections and depends on aiodns, pyasn1, and pyasn1-modules for DNS resolution and cryptographic operations. It ships with prebuilt wheels for Python 3.11–3.14 on Linux platforms, though building from source requires cargo if your platform lacks a wheel. The core pattern is to subclass ClientXMPP, register event handlers, and run the connection loop with asyncio—making it straightforward to integrate XMPP into async Python applications.
Use it for
- Build a real-time chat bot or client that connects to an XMPP server and responds to incoming messages asynchronously.
- Implement a presence-aware application that tracks user online/offline status and roster changes over XMPP.
- Create an XMPP component or gateway that bridges XMPP with other messaging systems or services.
- Develop multi-user chat (MUC) applications that manage rooms, participants, and group messaging.
- Integrate XMPP-based notifications or alerts into a larger async Python service or microservice.
