Project Visibility: Public vs Private

• Free users:
  All projects are automatically Public. These public projects are listed under the Built with Rocket tab on the landing page, making them openly accessible for anyone to browse and explore. If you want to make a project Private, you’ll need to upgrade to a paid plan.

• Paid users:
  All new projects are Private by default. You can choose to make them Public at any time if you’d like to share them more broadly.

• Before starting a project:
  On the Rocket homepage, right above the input field or project-type chips, you’ll see a toggle. Paid users can choose their preferred visibility setting here.

• Inside an existing project:
  Once your project is open, look at the top bar next to your app’s name. Click the visibility icon to open a dropdown - you can change your project’s visibility right from there.

Select your framework

Based on your selected platform, Rocket will recommend a framework setup and you can customize it if needed.If you selected Web App:
Rocket uses a default stack to get things moving fast:
