Bolt

Bolt (bolt.new) is an AI-powered full-stack development platform built on StackBlitz's WebContainers technology. It runs an entire Node.js development environment directly in your browser, giving AI agents — and by extension, you — complete control over the application lifecycle without a single local install.

**How it works**: Describe your app in natural language. Bolt generates a working project (frontend + backend + database schema), runs it live in-browser, and lets you iterate through follow-up prompts. Every change is reflected instantly in the live preview.

**AI backbone**: Bolt is primarily powered by Anthropic's Claude models. As of 2026, it supports Claude 3.5 Sonnet for fast iteration and Claude Opus 4.6 (with adjustable reasoning depth) for complex architecture work. The AI has full access to the terminal, filesystem, and browser — not just the editor.

**Key features**: - In-browser full-stack environment (no local Node, no Docker) - Multi-file editing with context across the entire project - Native Supabase, Netlify, and Vercel integrations - One-click deploy to production - Import from GitHub or start from scratch - Collaborative sharing via live preview URLs - Token-based pricing — pay per generation, scale as needed

**Pricing**: Free tier includes 300K daily tokens and 1M tokens/month with Bolt branding. Paid plans remove limits and branding. Bolt is ideal for rapid prototyping, MVP development, and non-technical founders who want to ship without touching a terminal.
