Straight answers. No pitch deck.

A private app builder on your machine. Create a real app, run a localhost preview, change it in Build chat, then Go Live for a public HTTPS URL — with domains, secrets, and plugins in the same place.

Spawn edits real project files, shows the preview on your machine, and ships a public URL with domains and secrets included. It’s a builder loop — create → run → build → live — not a one-shot chat that dumps disposable code. See Why Spawn.

A machine that can run Spawn, and (when invited) a private beta seat. Describe an app or open existing files, hit Run for a localhost preview, then iterate in chat. No separate deploy dance just to try a change. Walkthrough: How it works.

Building stays local. Project files, preview, and secrets live on your machine until you choose to publish. Go Live puts a public site on the internet; the builder is not a browser-only sandbox that holds your code.

Code stays on your machine until you publish. Secrets (API keys, env vars) live in Spawn’s Secrets and inject at run and deploy — not in your source tree. This site’s waitlist email handling is on Privacy.

Go Live opens a shareable public HTTPS URL from your machine. Fast path: Ship → Open to the internet, then copy the link or scan the QR. Same project you ran on localhost — keep iterating from Spawn. Tunnel URLs can refresh after reconnect; Reconnect / Auto-start keeps the saved URL current.

Yes. Attach your hostname from inside Spawn — no separate hosting console. For lasting traffic, point DNS (A/@) at your public WAN IP and forward the Forge port on your router; Spawn shows the target IP and verify steps. Tunnel links work without port-forward when you just need a shareable HTTPS URL now.

Yes for lasting traffic on this path — Spawn publishes from your machine. Keep the PC awake (Start with Windows helps) and optionally enable Auto-start Public URL so the tunnel comes back after reboot. This is honest private-machine shipping, not a rented always-on host pretending to be local.

Spawn is in private beta. Join with your email on early access. We invite in waves and email when it’s your turn — no spam, no pitch-deck drip. Honest seat counts; no fake waitlist theater.

Not publicly. Private beta first. Join early access and we’ll share plans when seats open — building in public on spawnapp.org.
