Bolt
AI-powered full-stack web development in your browser
About Bolt
Bolt.new is an AI-powered app builder by StackBlitz that generates complete full-stack applications directly in your browser from natural language prompts. Built on WebContainers technology, it lets you prompt, run, edit, and deploy production-ready web apps without any local setup, supporting React, Next.js, Vue, Svelte, and more.
Pros & Cons
Pros
- Generate production-ready MVPs in minutes rather than hours or days
- Zero setup required — everything runs in the browser via WebContainers
- Supports all major modern frameworks with npm package installation
- Clean, well-structured production-quality code output
- Intelligent AI-assisted error detection with contextual fixes
- Seamless one-click deployment to go from prompt to live URL in minutes
Cons
- Token consumption is aggressive and unpredictable — simple bug fixes can burn millions of tokens
- AI frequently rewrites entire files instead of making targeted changes during debugging
- Struggles with large or complex projects as architectural coherence breaks down
- Poor customer support with reports of zero response to emails and tickets
- Cannot push projects to GitHub, severely limiting team collaboration and version control
