Bolt.new

What Bolt.new is

Bolt.new, from StackBlitz, turns a chat prompt into a full-stack web app that runs live in your browser. There's no local setup and no waiting: you describe what you want, watch it build in a real code sandbox, click through the running result, edit the code if you like, and deploy. It deliberately sits between a no-code app builder and a coding environment — more hands-on than the former, far less ceremony than the latter.

Where it earns its score

The in-browser experience is the draw. Because StackBlitz has spent years making a full development environment run in the browser, Bolt gives you something most prompt-to-app tools don't: a genuine, editable sandbox with instant preview. For people who like to see the code and nudge it, that transparency builds trust the black-box builders can't. It's fast, it's shareable, and it gets you to a clickable app quickly.

The catch

Bolt runs on a token/credit model, and heavy iteration — the exact loop that makes these tools fun — consumes tokens quickly, so budget for it. And like every prompt-to-app tool, the further you push into complex or unusual logic, the more you need to understand what was generated to keep going. It rewards technical comfort more than a builder that hides the code entirely.

Bolt.new is the prompt-to-app tool for people who want to keep one hand on the code.

Who it's for

Reach for Bolt if you want prompt-to-app speed but like watching and editing the code as it's built. If you'd rather the backend, auth, and hosting were handled with the least code contact possible, Lovable leans further that way — and plenty of builders keep both around. Start on the free tier to see whether the workflow fits before the tokens matter.
