Our take
A powerful in-browser app builder that routes to the best model per task and now handles much larger projects, ideal for rapid full-stack prototyping.
Best for
Product builders and entrepreneurs who want to go from idea to a running, hosted app inside the browser.
Pros
- Runs entirely in-browser with no local setup (built on StackBlitz)
- Automatic model routing balances quality and cost
- Import from Figma or GitHub; built-in hosting and databases
- Strong for production-style full-stack apps
Cons
- Token/credit usage can climb on big builds
- Still benefits from developer oversight for complex apps
- Free domain and perks are promotional, not permanent
How it compares
A direct rival to Lovable and v0; Bolt emphasizes in-browser execution and design-system imports for production apps.
Full review
Bolt.new, from the StackBlitz team, is a browser-based AI builder that creates full-stack apps and websites from a prompt and runs them instantly in an in-browser dev environment. It automatically routes each task to an appropriate model, and recent updates let it handle projects far larger than before with improved context management.
Beyond generation, Bolt Cloud provides hosting, databases, authentication, and SEO tooling so a project can go from idea to live product without stitching together separate platforms. It can import a company design system or pull from Figma and GitHub. As with all vibe-coding tools, complex builds still reward a developer's review, and credit consumption is worth watching, but Bolt is one of the most capable options for fast, professional prototyping.
