Open a tunnel to a port on a machine

Give a local app, like a dev server on port 3000, a public web address.

Open Fabric

Steps

  1. Click Tunnels & Served Files in the side menu, then + New tunnel at the top right.
  2. Choose the Machine the app runs on.
  3. Type the Local port, for example 3000, and a Label (optional) like Next.js dev.
  4. Click Open tunnel.

What happens next

You get a public address ending in fabric.ocalt.site. Anyone with it reaches the port on your machine.

Good to know

  • To close it, find it under Open tunnels and click Close.
  • You can later point your own domain at it from Domains & Subdomains.
