Browser support

Bolt works best in Chrome and other Chromium-based browsers on desktop.
Mobile browsers are not fully supported in Bolt yet.
Examples of Chromium-based browsers include the following:
  • Microsoft Edge
  • Brave
  • Vivaldi
  • Opera
  • Epic
Browser extensions such as ad blockers, privacy tools, or VPNs can sometimes cause issues. If things aren’t working as expected, try turning them off and refreshing the page.

​
Platforms

You can use Bolt to build websites, web apps, and even mobile apps. Bolt projects can be turned into mobile applications using Expo.
Include the words mobile app in your initial prompt to direct Bolt to create an Expo-compatible app.

​
Languages and frameworks

Bolt focuses on JavaScript-based web technologies. It supports:
  • Node.js for the backend.
  • Browser-native code: any JavaScript framework that runs on the frontend.
Bolt only supports JavaScript-based backends, so languages such as PHP or Python aren’t compatible.

​
Databases

Bolt offers built-in database creation and management through Bolt Cloud. You also have the option to connect your project to Supabase for more advanced database management and configuration.
