Bolt.new
Build complete web apps and sites with AI in your browser, nothing to install
What is Bolt.new?
Bolt.new is an AI-powered web app builder that lets you create full websites, apps and prototypes using natural language prompts. Built by StackBlitz, it runs real code in your browser using WebContainers, so you can develop, edit and deploy full-stack applications with no local setup. Perfect for founders, designers and developers who need to go from idea to working product fast.
Pros
- All-in-one interface: code, preview, terminal and versions built in, without leaving the browser
- WebContainers in the browser: runs native Node.js in the browser, no cloud VMs or local install
- Open source: repository available on GitHub for self-hosting via bolt.diy
- Multi-framework support: React, Vue, Svelte, Next.js, Astro and more JavaScript frameworks
Cons
- English-only interface: documentation, help centre and support are entirely in English
- Unpredictable token usage: complex projects burn through billions of tokens quickly
- Limited context: loses the thread on apps with 15-20+ components, needs manual refactoring
Frequently asked questions
Can I write prompts in Spanish?
Yes, the underlying Claude model is multilingual and understands Spanish. But the Bolt interface itself is still English.
What are tokens?
They are the unit of usage in Bolt. The free plan gives 1M tokens/month; every prompt and run consumes tokens depending on complexity.
Can I export my code?
Yes, download it as a ZIP or connect directly to GitHub for version control and deployment.
