Iroh is a Rust networking library that establishes direct peer-to-peer QUIC connections between endpoints dialed by public key, with NAT hole-punching and relay fallback. It is modular and composable, with ecosystem protocols for blob transfer, gossip, and CRDT-style document sync.

Use cases

• connect two devices directly without a central server
• add peer-to-peer encrypted connections to my app
• transfer files between machines behind NATs
• build a real-time sync or chat application
• stream video between devices peer-to-peer
• tunnel remote access without a VPN
• connect distributed GPU compute across clouds

When to choose

• you need direct, encrypted device-to-device connections that work across NATs and firewalls
• you want public-key-based dialing instead of managing IP addresses and ports
• you're building local-first, offline-first, or P2P applications
• you need cross-platform networking including mobile and embedded targets

When to avoid

• you only need simple client-server HTTP communication
• you require a mature battle-tested VPN or mesh solution like WireGuard or Tailscale with enterprise support
• your stack cannot use Rust or the available FFI bindings
• you need TCP-only environments where UDP/QUIC is blocked and relays are unacceptable
