About Bolt

Bolt (bolt.new) is an AI-powered full‑stack development agent that lets users prompt, run, edit, and deploy web applications entirely in the browser. It integrates large language models with an in‑browser development environment powered by StackBlitz WebContainers so projects run live without local installation. Users can iterate via natural-language prompts, preview and edit generated code, and deploy projects that run on the same web runtime. An official open-source variant (bolt.diy) enables choosing the LLM per prompt for greater control and privacy. Paid subscriptions are available to increase AI token limits and enable private projects.
