About Bolt.new

Bolt.new is StackBlitz’s AI app builder that turns prompts into full-stack websites and apps right in the browser. Powered by Opus 4.6 for adjustable AI reasoning, with built-in Figma import, AI image editing via Nano Banana, autonomous debugging (Bolt v2 cut error loops by 98%), and Bolt Cloud — databases, auth, file storage, edge functions, analytics, and hosting all in one platform. Free to get started; Pro tiers ($20 and $50/mo) add more AI tokens + private projects. Token-based pricing — heavy users have reported burning through allocations fast.
