Domains
Point app.yourdomain.com at your live app from inside Spawn.
Product
A private builder. Every surface to ship.
Spawn is an app builder that runs on your machine — real files, live preview, chat to change them — then a public URL when you’re ready. Domains, secrets, plugins, and account stay inside the same product.
- Private machine
- Public URL
- Eight builder surfaces
- Private beta
Private machine → public URL
Everything starts local. Source, secrets, and uncommitted work stay on your machine until you press Go Live. Open to the internet for a shareable HTTPS link from this machine; lasting custom domains need DNS + port-forward — without leaving Spawn.
Builder surfaces
Eight capabilities in one product — feature-forward, not a walkthrough. Jump any surface; Tour and How cover the loop.
-
Create
Start a real app
Describe what you’re building or open files already on disk. Spawn scaffolds a project on your machine — not a throwaway sandbox.
-
Run
Local preview
Hit Run and see the app live on localhost. Same process you’ll ship — no deploy required to try a change.
-
Build chat
Change it in English
Ask for a pricing table, auth flow, or layout fix. Spawn edits the files, shows the diff, and refreshes the preview — with your keys, on your project.
-
Go Live
Public URL
Open to the internet for a copyable HTTPS link (and QR) from your machine. Share it, keep iterating — without switching tools to ship.
-
Domains
Your hostname
Attach a custom domain from inside Spawn. Lasting traffic needs DNS to your WAN IP plus router port-forward — Spawn shows the steps.
-
Secrets
Keys stay put
Store API keys and env vars in Secrets. They’re injected at run and deploy time — they don’t live in your source tree.
-
Plugins
Extend without leaving
Wire auth, storage, email, and more from inside the builder. Production pieces stay in one place — not a pile of side consoles.
-
Account
Your seat, your machine
Sign in, manage invites, and keep builder settings with you. Private beta seats land here first — honest invite waves, no fake wait counts.
Ship kit
What Go Live unlocks — domains, secrets, and plugins as first-class surfaces, not afterthoughts.
Secrets
Env vars injected at run and deploy — never checked into the repo.
Plugins
Auth, storage, email, and more without bouncing between dashboards.
