localhost.run

localhost.run is a client-less tunneling service that makes locally running HTTP, HTTPS, or TLS applications reachable from the public internet. There is no client to install and no account needed for the free tier — it works over plain SSH, which is already available on most operating systems.

When to use this skill

Use this skill when the user wants to:

• Share a locally running app with someone (preview link, demo, QA)
• Receive webhooks (Stripe, GitHub, Twilio, etc.) on a localhost dev server
• Test an app from a phone or another device on a different network
• Tunnel a database or other non-HTTP protocol through a Custom Domain
• Set up a Custom Domain on localhost.run
• Diagnose an existing localhost.run tunnel that is broken, slow, or unstable
• Replace tools like ngrok, Cloudflare Tunnel, or localtunnel
