Bolt.new
AI app builder by StackBlitz that creates, runs and deploys full-stack web apps from prompts in the browser.
What is Bolt.new?
Bolt.new is an AI-powered app builder from StackBlitz. You describe the app you want in a chat, and Bolt writes the code, installs packages and runs the app in your browser. You can then edit, iterate and deploy without setting up a local development environment.
Bolt.new is built on StackBlitz WebContainers, a technology that runs Node.js development environments inside the browser. That lets the AI not only write code but also install dependencies, run a dev server and show a live preview in one tab.
You start with a prompt such as "build a habit tracker with login", and Bolt generates a project with front end and back end code. You keep chatting to change features, fix errors or adjust design, and you can also edit files directly.
Bolt supports popular frameworks and offers integrations for things like databases and authentication, plus one-click deployment and hosting options. You can also export the code or connect it to GitHub to continue development elsewhere.
It is popular with founders, designers and developers who want to go from idea to working prototype quickly.
