Bolt

Bolt is an AI app builder from StackBlitz that writes and runs a full-stack web app inside the browser. You type what you want, it scaffolds the project, installs packages and shows a live preview, and you can keep prompting or edit the files directly.

Because the code is visible and downloadable, it suits founders who want a fast start but expect a developer to work on the project later. It can deploy to a hosting provider in a click and connect to a database service.

Watch how quickly a large project uses up your token allowance, keep the project small and focused at first, and read through the generated code for secrets or keys before you share or deploy it.
