n0-computer releases Iroh 1.0, a stable peer-to-peer networking library that allows devices to connect securely using public keys instead of IP addresses.
Iroh has released version 1.0, its first major stable release, establishing a stable foundation for peer-to-peer networking. Built by n0-computer, Iroh replaces traditional IP addresses with cryptographic keys, allowing secure, direct connections that bypass NATs and firewalls. Over 200 million endpoints were created on Iroh's public relays in the last 30 days alone. The 1.0 release adopts open IETF standards, features custom implementations of QUIC multipath and NAT traversal, and introduces stable FFI support for Python, Node.js, Swift, and Kotlin alongside the original Rust crate. Iroh now guarantees wire protocol and language API stability, providing developers with a robust, enterprise-ready decentralized networking stack.
By replacing geographic IP addresses with cryptographic public keys, Iroh offers a highly elegant solution to the perennial challenges of firewalls, NAT traversal, and dynamic IPs, priming it to be a key enabler for local-first software and decentralized agent networks.
* **Cost-Efficient Direct Routing:** Up to 95% of data is routed directly between devices, eliminating expensive cloud egress and server middleware.
* **Robust Multi-Language Ecosystem:** Official bindings for Python, Node.js, Swift, and Kotlin allow developers to embed secure P2P connections into native mobile, web, and backend environments.
* **Extensible Custom Transports:** Built-in support for WASM and integrations like Tor or Bluetooth Low-Energy (BLE) provide developers with maximum flexibility across diverse networking environments.
* **Enterprise Stability Guarantees:** Separating language API versioning from wire protocol versioning, combined with clear public relay deprecation schedules, makes Iroh viable for production-grade, long-lived applications.
