Spawn

Build in the browser · Ship from your machine

Build an app.
Put it on the internet.

Start on spawnapp.org — create from a template, preview live, edit with Build chat. A lasting public URL still needs Spawn desktop (Ship → Open to the internet). Domains, secrets, and plugins stay on your machine.

Shareable HTTPS from this machine — tunnel can refresh; PC stays on for lasting traffic.

Go Live — Ship → Open to the internet; lasting domains need DNS + port-forward; PC stays on.

Private machine → public URL

Source and secrets stay local until you press Go Live. Ship → Open to the internet for a shareable HTTPS link (and QR) from this machine — without leaving Spawn.

How public actually works

Same honesty as How it works — home is where most people decide, so the internet path stays precise.
