Why libp2p?

libp2p is a modular system of protocols, specifications and libraries for the development of global-scale peer-to-peer applications.

Multiple Transports

TCP, QUIC, WebSocket, WebRTC, and WebTransport. Use what works best for your environment.

Native Roaming

Move between networks and addresses seamlessly. Your connections follow you.

Runtime Freedom

Run in browsers, mobile devices, or servers. No runtime restrictions.

Protocol Muxing

Multiplex multiple protocols over a single connection with automatic negotiation.

Encrypted Connections

All connections are encrypted by default with Noise or TLS 1.3.

NAT Traversal

Built-in hole punching, AutoNAT, and relay support to connect peers behind NATs.

Production-Ready Implementations

Choose the implementation that fits your stack. All implementations follow the same specifications for cross-language compatibility.
