Bolt.new — Full-Stack in the Browser
Prompt → running full-stack app (frontend + backend + DB) in a WebContainer. No local setup.

Where the Magic Happens
WebContainer tech runs Node.js in the browser — real npm, real Vite, real Supabase/Postgres. You get a URL that works. Share it, iterate, deploy to Netlify/Vercel in one click.
Where Friction Lives
No git history — it's a sandbox, not a repo. Can't import existing projects. Context window chokes on >20 files. No offline, no local fallback. Vendor lock-in to StackBlitz ecosystem.
PM Recommendation
Git sync (push to GitHub from Bolt). Import existing repo. Local CLI (`bolt dev`) that spins the same WebContainer. Make it a workflow tool, not a demo playground.
