Bolt.new
StackBlitz's in-browser agent that builds and runs full-stack apps from a prompt.
Add Bolt.new to your hut →Bolt.new is StackBlitz's AI app builder — describe what you want and it generates a full-stack web application running live in the browser. It uses WebContainers to run Node.js entirely in-browser, which means the generated app is testable instantly with no local setup. The agent handles frontend, backend, database schema, and deployment in one conversation. It's particularly popular with non-developers and founders who want to validate ideas without a developer.
The free tier has limited daily messages. Pro ($20/mo) unlocks significantly more usage. Most often compared to Lovable (similar concept, more polished UI output) and v0 (frontend-focused, more targeted to components).
