Overview
Bolt is StackBlitz's AI app builder that works in your web browser. You describe what you want in a prompt; it writes the app, shows it in a live preview and can add a database, sign-in and file storage through its built-in Bolt Cloud. You can publish the project to a free bolt.host web address, and mobile apps are built through its Expo integration. It suits people with no coding experience as well as developers, product managers, marketers and students.
The code it writes is yours to use, including for commercial projects, and you can open and edit it yourself in Code view.

| Plan Mode | Talk through the app with Bolt before it writes any code | Your Bolt account |
| Built-in database | Adds tables, sign-in and file storage to a project without extra tools | Bolt Cloud |

Good to know
You need a landing page, a small web app or a prototype and you don't code. Bolt builds it from a prompt, shows a live preview you can test and publishes it to a web address in one step.
Limits
- Prompts use tokens: the free plan has 1M a month with a 300K daily limit, and apps with a database take longer and use more.
- Custom domains need a paid plan, and free published sites show Bolt branding.
