Bolt.new

Bolt.new gives you a full Node.js and Vite development environment running entirely in your browser tab. No local setup, no Docker, no waiting for cloud VMs to spin up. The WebContainers runtime handles npm installs, dev servers, and test runners without touching a backend server. You write prompts, the AI writes code, and you watch it execute immediately in the same window. The v2 release in October 2025 addressed the main pain point of early AI coding tools: endless error loops. StackBlitz claims a 98% reduction in debugging cycles through autonomous error correction, now running on Claude Opus 4.6. When you're done iterating, one click deploys to Netlify with a live URL — no separate account creation required. The tool grew from zero to $4M ARR in its first 30 days, which tells you something about pent-up demand for browser-native full-stack environments. It's now one of the four tools (alongside Lovable, Base44, and v0) that define the vibe-coding category. The free tier gives you 1M tokens monthly, enough to test whether the workflow fits before committing to the $25-50/month paid plans.

• Run full Node.js stacks in-browser — npm install, dev servers, and tests work without any backend infrastructure
• Deploy to Netlify in one click with editable subdomains, no separate signup needed
• Import Figma designs as starting points and edit images with built-in AI tools
• Share team templates for consistent project scaffolding across your organization
• Debug autonomously with v2's error correction that reduced failure loops by 98%
• Switch between AI-generated code and manual edits in the same environment
