The platform doesn’t lock you into one tool: the shared configuration in your project’s local-configuration repository feeds all supported IDEs and AI tools with the same rules and settings. The setup app installs them on request and opens projects in your tool of choice with one click.
Our recommendation: VS Code
For getting started we recommend Visual Studio Code:
- The Application Platform extension ships a welcome page with all repositories of your project, start buttons (
ap run-local), and quick links – the setup app installs it automatically. - Free, available on all operating systems and, in a remote workspace, directly in the browser (VS Code Web).
- Cursor and Antigravity are built on VS Code – switching later is seamless.
In the setup app’s settings you choose the default tool used to open projects.
