What is Bolt.new?
Bolt.new (by StackBlitz) is a browser-based AI development environment. You type a prompt, Bolt scaffolds a real project - Vite, Next.js, Astro, Remix - runs it in a WebContainer, and lets you edit the code live.
Why developers love it
- Real dev environment in the browser - terminal, file tree, package manager
- Supports any npm package
- Token efficient: shows you exactly what credits you spent
- Excellent for prototyping a feature before merging into your main repo
Tradeoffs
Bolt assumes you can read code. Errors are not gracefully recovered the way Base44 hides them. Hosting is BYO (Netlify, Vercel) - Bolt builds, you ship.
Pricing
Tokens-per-month plans, starting around $20/mo for serious use. Free tier is generous for tire-kicking.
Verdict
Pick Bolt when you are a developer and you want AI as a faster pair, not as a no-code abstraction.
Pros
- runs in browser, no setup
- hot reload
- code-level control
Cons
- steeper learning curve than Base44
- less opinionated about backend
