How Foundation Base compares

Typical templateFoundation Base foundation
Often starts from screenshotsStarts from a working demo
Generic setup notesIncludes source, setup, and AI-agent instructions
You still invent the app flowYou customize a real runnable app
Install path may be unclearApp Link and install guidance are part of the loop

The Foundation Base demo does not update when you customize your copy. Install your own App Link after you deploy.

Demo Link

The original Foundation Base version. Good for trying the app.

Preview Link

A temporary testing link while your app is being customized.

App Link

Your stable deployed URL. Install this version if you want your changes to appear on your phone or desktop.

Questions

What happens when I click Create My App?

You download an editable source package with setup files and AI-agent instructions. Your copy is separate from the Foundation Base demo.

Does the Foundation Base demo update when I customize my copy?

No. The demo is the original shared version. Install your own deployed App Link when you want your customized app on a device.

Can I use Claude Code, Codex, Cursor, or another agent?

Yes. Foundations are designed to be opened by an AI coding agent after you download and unzip the source package.

Built for safe starting points

Every foundation is treated as code, not content. Contributions are reviewed before publication, and foundations are checked for hidden network behavior, unsafe scripts, secrets, and unclear setup paths.
