Bolt.new (StackBlitz)

In-browser full-stack app builder

Free tier + paidAI app buildersbolt.new

What it is

Runs a real Node toolchain inside the browser via StackBlitz WebContainers, so npm install, dev server and terminal all work client-side. Generates Vite, React and Next projects, deploys to Netlify or Vercel, and exports to GitHub or ZIP. A May 2026 Microsoft partnership added Azure deploy and Microsoft 365 integration.

Why it earns a slot

The closest thing to a real dev environment in a browser tab — you watch and edit the file tree while the agent works. Pick it over Lovable when you want framework freedom and terminal access rather than a guided rail.

Know before you commit

Token-metered, and failed builds or error loops still burn tokens. The free tier's 300K daily ceiling is consumed by one meaningful feature. WebContainers cannot run native binaries or Python, so some backends are simply off the table.

Getting started

Prefix any GitHub repo URL with bolt.new to import it directly.
