IP addresses break, dial keys instead
Add peer-to-peer connectivity to your app, agent, or workflow.
“Iroh is the magic behind our ability to facilitate millions of private backbones in minutes. Impossible with traditional networks.”
Drew Raines
Head of Engineering at Datum
“Using iroh halved our compute budget.”
Ari Lotter
Principal Engineer at Nous
“With iroh, every node is just a public key. We pool GPUs across clouds and closets into one mesh. No central server, no NAT config.”

Resilient by default
Built for environments where connectivity is unreliable or intermittent
Lower infrastructure costs
Move data directly. Pay the cloud less.
Iroh connects endpoints peer to peer whenever it can. Your application data can stay on your endpoints—no cloud storage required. Relays only forward end-to-end encrypted packets when a direct path is unavailable, cutting cloud egress and the infrastructure you have to operate.

Open source.
Forever.
iroh is an open source peer-to-peer networking stack built on open standards, so you're never locked in. Connect over our free community infrastructure, self-host your own, let us host services for you, and switch between them anytime.
How are people using iroh?
Embed direct, encrypted connections right in your app and create tunnels for remote access instead of third-party VPNs.
Train foundation LLMs with compute distributed around the world, across AWS, GCP, Azure, and self-hosted infrastructure.
Stream video between devices, using peer to peer technology. Create encrypted connections built on open standards, across the globe or across the room.
Real-time Sync for Mobile Applications
Powers apps for hundreds of thousands of devices around the world, even when internet access is precarious.
Connect payment terminals directly to point of sale systems over Bluetooth, LAN, or Wi-Fi with full PCI compliance and no additional servers.
Run iroh on ESP32, Raspberry Pi, and Linux with the same API. Devices discover each other automatically. No brokers, no gateways.
Built to ship
Ready for production
Modular toolkit
Dozens of open-source, composable protocols built on top of iroh. Mix & match to get the feature set you need.
