Bolt.new
Generate, run, and deploy full-stack web apps directly in the browser using WebContainers — no local setup required. Token-metered pricing with unused tokens rolling over one month.

Overview
Bolt.new is a browser-based AI development environment by StackBlitz where you describe what you want to build and receive a working, runnable full-stack application, all in the browser, with no local setup required. It combines an AI model (Claude or GPT-4) with a full in-browser Node.js runtime, file system, and terminal, so the AI can write code, install packages, run the app, observe errors, and fix them in a self-contained loop. The result is a genuinely interactive development environment where the AI iterates until the app works, not just a code generator that outputs a static file. Applications built in Bolt.new can be deployed directly to Netlify with one click.
Typical use cases: rapid MVP prototyping, building small internal tools, creating demo applications for pitches, and learning new frameworks by watching the AI build example applications. The free tier provides limited monthly usage. Paid plans start at $20/month for more AI interactions and higher compute. Bolt.new competes directly with Lovable and Replit Agent for the 'full-stack app from a description' use case.
