Osir Tunnel

Expose a local web server to the internet over HTTPS in one command. No account, no config.

With the OSIR CLI

osir tunnel 3000

One binary for Windows, macOS and Linux.

Or without installing anything (needs Node.js 18+)

curl -fsSLO https://osir.run/client.js
node client.js http://localhost:3000

You'll get a random public URL like https://quiet-river-7k2p.osir.run. It stays up while the client runs and is gone when you stop it.

Quick tunnels are for testing and demos. Don't use them for anything illegal or for phishing; abusive tunnels are shut down. Run by Osir.
