Bolt.new

Bolt is what you get when a developer-tools company (StackBlitz) builds a vibe coding platform: fast, transparent, and unwilling to hide the machinery. Its signature trick is running a real development environment entirely in your browser — project files, terminal, dependencies — so you watch your app take shape like a developer would, without installing anything. It grew explosively on that promise (over $40M ARR within months of launch) and remains the platform of choice for builders who want to see what the AI is doing.

Its second genuine differentiator is framework freedom. Where Lovable is React-only and Base44 abstracts the question away entirely, Bolt happily scaffolds React, Vue, Svelte or Astro — if you have opinions about frameworks, this is the only major app builder that fully respects them. Pro at $25/month brings 10M tokens with rollover, no daily limits, custom domains and SEO features; the free tier (1M tokens/month) is enough for an honest trial.

The honest trade-offs: the backend is not turnkey — database and logins typically mean connecting your own service (like Supabase), which is a genuine step up in required understanding. Token pricing scales with project size, so big projects burn noticeably faster per instruction. And the visibility that developers love is cognitive load for everyone else. If you're a non-technical professional who just wants a working business site, our recommended alternative box exists for you: Base44 or Lovable will carry you further with less friction.

Like sitting in the passenger seat with the dashboard fully visible — files appearing, terminal scrolling, dependencies installing. Exciting if you're curious, noise if you're not. Iterations feel quick (the in-browser environment is genuinely fast), and starting from templates or importing an existing project works better here than anywhere else in the category. Keep projects lean: token consumption grows with project size, so sprawling apps cost more per change.
