What is Bolt.new?
Bolt.new is a browser-based AI app builder from StackBlitz, a company founded in 2017 by Eric Simons and Albert Pai. You describe an app in plain English, and Bolt.new writes the frontend, backend and dependencies for you. It launched publicly on October 4, 2024.
The standout fact is where it runs. Node.js, npm, the build process and the dev server all run inside the browser through WebContainers, so you install nothing locally. That removes the setup step that stops many non-developers.
How to Get Started with Bolt.new
- Open bolt.new and create a free account. Sign-up takes a minute, and you land in the prompt box. The free plan is enough for a first test.
- Write a specific first prompt. Name the app type, the main screens and one key behavior, such as “a booking app with a calendar and email confirmation.” Specific prompts use fewer tokens than vague ones.
- Review the live preview. Click through every screen and note what is wrong. Make a short list before you ask for changes.
- Make small, scoped edits. Ask for one change at a time, like “add a cancel button to the booking card.” Large “rewrite the page” prompts burn through tokens fastest.
- Deploy, then export. Use the deploy option to publish on a host such as Netlify. When you are ready to keep building, upgrade to Pro and export to GitHub.
Bolt.new vs Competitors
Bolt.new vs Lovable. Lovable covers similar ground as a prompt-to-app builder, and one editorial review notes Lovable and v0 cover similar ground, with Bolt.new best for quick, deployable prototypes. Choose Bolt.new when you want a full-stack project that runs in the browser and exports cleanly. Choose Lovable if its workflow or output style fits your project better after you test both on the same prompt. The key difference is how each tool meters usage, so compare real costs on one small project.
Bolt.new vs Replit. Replit is the broader platform. One pricing guide describes Core at roughly $20-25 a month with effort-based agent pricing and included hosting, the most complete platform but the least predictable bill. Choose Replit when you want hosting and the whole environment in one place. Choose Bolt.new when you want a fast prototype and prefer to deploy to your own host. Bolt.new’s token meter is easier to reason about, but it can run out quickly on large codebases.
Final Verdict
Bolt.new is best for founders, product managers and developers who need a working full-stack prototype quickly. Its standout feature is the in-browser runtime that removes all local setup. The honest caveat is token usage: debugging loops and large files can drain your allowance fast. If you keep prompts focused and treat the output as a prototype, it earns a spot on your shortlist.
