Product tour
Walk the product UI
Three screens inside Spawn — Build with chat, Run on localhost, Ship a public URL. Real files on your machine. Jump any step.
-
Build
Describe the change. Spawn edits real files, shows the diff, and refreshes the preview — you’re in a builder, not a throwaway demo.
- Chat edits land as diffs you can read
- File tree + open tabs stay in view
- Same workspace you’ll ship from
-
Run
Hit Run and the app starts on localhost. Same process you’ll ship — click it, hot-reload it, keep iterating until it feels right.
- Real localhost process, not a mock render
- Hot reload as Build chat lands changes
- Deploy stays optional until you’re ready
-
Ship
Go Live opens a shareable public HTTPS URL from your machine (Ship → Open to the internet). Attach your domain, load secrets and plugins — without leaving the builder.
- Private until you press Go Live
- Public HTTPS from your machine — copy or QR
- Custom domain: DNS + port-forward for lasting traffic
- Iterate after — Build chat still works
