What is Bolt.new?
Bolt.new is an AI-powered web development environment built by StackBlitz, launched in late 2024. It combines AI code generation (powered by Claude 3.5 Sonnet) with StackBlitz's WebContainers technology to run a full Node.js environment directly in your browser.
This means Bolt can create, run, edit, and deploy complete full-stack applications — React, Vue, Next.js, Node.js backends — all without any local setup. It became viral almost immediately, with developers showing off complete apps built in minutes.
