Use Case: Networking

Zero-trust connectivity

Teams are replacing Tailscale, WireGuard, and reverse SSH tunnels with iroh—dial a device's public key and get a direct, encrypted connection. No coordination server to run, no ports to open, no third-party app to install.

Why iroh

iroh vs. Tailscale & WireGuard

irohTailscale / WireGuard
Embeds directly in your app
No separate client to install
NAT & firewall traversal
End-to-end encrypted by default
Whole-device network overlay

Iroh connects your app's own devices directly—it's not a general-purpose replacement for joining a whole network of unrelated machines.

The Problem: VPNs Are Infrastructure You Didn't Want to Own

Reaching a device that isn't sitting on the public internet usually means standing up a VPN: a coordination server to run and secure, client software to distribute, and firewall rules to get right. Or it means reverse SSH tunnels and all the operational shenanigans that come with them.

“It's Tailscale, but as a library. Instead of standing up VPN infrastructure—coordination servers, client software, all the network shenanigans—we dial a device's public key directly from inside our own app and get a direct, encrypted connection.”

But what if your app could just dial the other device directly—no separate network to join, no client to install, no infrastructure to babysit?

The Solution: Dial Keys, Not IPs

Every iroh node has a public key as its address. To reach a device, you dial that key directly from inside your own application—there's no separate VPN client for your users to install, and no central network your traffic has to join.

Dial Keys, Not IPs

Every node has a cryptographic identity. Connect to a device by its public key, wherever it is.

Direct Connections

Iroh punches through NATs and firewalls automatically to connect devices directly.

Encrypted by Default

Every connection is end-to-end encrypted, so your platform can't see or modify traffic between devices.

A Library, Not a Client

Iroh ships inside your app, so the connection is just part of your product—not a separate piece of software your users manage.
