AI web development agent that builds, runs, and deploys full-stack apps from natural-language prompts in the browser.
Bolt is an AI web development agent from StackBlitz that turns natural-language prompts into running full-stack web applications directly in the browser. Generated code executes inside WebContainers, a WebAssembly-based runtime that boots Node.js development environments in milliseconds within the browser tab, and finished projects publish through Bolt Cloud hosting with databases, authentication, custom domains, and built-in search engine optimization tooling.
Launched in October 2024, the platform reached $4 million in annual recurring revenue within four weeks and $40 million by March 2025 while serving millions of registered users. Bolt integrates services such as Supabase, Stripe, GitHub, Figma, and Netlify, and ships specialized agents for security auditing, design-system generation, and performance tuning.
