Build Map
Field guide
Publish path
Grok Build apps are backed by Vercel hosting/CDN. You prompt and preview; the platform runs the production build and publishes to a *.grok.me host, with hub discovery at hub.grok.me.
| Capability | Spec | Claim |
|---|---|---|
| Build gate | npm run build + typecheck must pass (Vercel process) | template |
| Env files | Do not create .env — platform injects on deploy | template |
| Public URL | *.grok.me (+ hub listing) | template |
| Runtime shape | Serverless / edge-style — no durable local FS writes | inferred |
| Multiplayer | P2P only — no multiplayer game server on this target | template |
Do not hand-author .env files in the builder sandbox.
