Bolt

About Bolt

bolt.new is a browser-based AI app builder that turns plain-text prompts into running full-stack web applications without any local setup. You describe what you want, and within minutes you have a live, deployable project complete with a database, user authentication, and hosting. No terminals, no package managers, no configuration files. The product runs on StackBlitz's WebContainer technology, which executes Node.js entirely inside your browser tab. That architecture is what makes the speed possible. When you open a new project, it's already running. When you describe a change, the agent applies it to a live environment. The feedback loop between prompt and working app is genuinely fast, and for getting a concept off the ground, that matters. The feature set is broader than you might expect at this price point. Bolt handles backend infrastructure out of the box: unlimited databases, auth flows, SEO configuration, and website hosting are included without any additional integrations. You can import directly from Figma or GitHub, which means it fits into existing workflows rather than demanding you start from scratch. Support for design systems including Material UI, Shadcn, and Chakra UI means you can set a visual standard and have the AI follow it consistently. The honest limitation is what happens after the first build. Token consumption scales sharply with project complexity. A simple prompt on a fresh project might use 10,000 tokens. Run the same prompt on a project with 20 components and you're looking at 100,000 tokens or more. When the AI gets something wrong and you ask it to fix the problem, it frequently rewrites entire files rather than the specific issue, which both burns tokens and risks breaking working parts of your UI. There are credible reports of developers spending significant money on a single debugging session without resolving the underlying error. Tokens are charged even when the AI fails to produce working output, and support responses on billing disputes have been inconsistent. The free tier is genuinely usable for small projects, though it comes with Bolt branding on your published sites. The Pro plan removes that and bumps the monthly token allowance substantially, with unused tokens rolling over. Teams pricing gives each member their own allotment rather than a shared pool, which is a reasonable call for collaborative work. StackBlitz, the company behind Bolt, raised over $135 million in total funding and was valued at roughly $700 million in early 2025. The founders have been building browser-based development infrastructure since 2017. This isn't a weekend project or a thin wrapper. The underlying technology is real and the team has genuine engineering depth. Bolt sits in useful territory between full developer tools like Cursor and more structured no-code builders. If your goal is a working prototype, a landing page, or an early MVP, the speed advantage is real. If you're planning to build something complex and iterate heavily, the token economics can work against you fast.
