Quick start

Claim two apps

localberth claim foo --port 5173
localberth claim bar --port 5174
localberth get foo

get prints only the port (5173), for scripts:

PORT=$(localberth get foo)

On Windows PowerShell:

$env:PORT = localberth get foo

localberth serve

Then visit http://127.0.0.1:54321. Loopback is the operator board. A phone on Tailscale or LAN sees the visitor tiles.

To reach an app from the phone, claim with --lan (or start the app on all interfaces):

localberth claim foo --port 5173 --lan
localberth serve --host 0.0.0.0

localberth ls
localberth scan

scan hides common OS ports unless you pass --all. It never kills a process.

Pin host and port from the lease. See Vite.
