> ⚠️ **Warning:** py-libp2p is an experimental and work-in-progress repo under development. We do not yet recommend using py-libp2p in production environments.
|
||||
> py-libp2p has moved beyond its experimental roots and is steadily progressing toward production readiness. The core features are stable, and we’re focused on refining performance, expanding protocol support, and ensuring smooth interop with other libp2p implementations. We welcome contributions and real-world usage feedback to help us reach full production maturity.
