How Foundry works

Three steps and no code: you say what the app should do, Foundry builds it and tests it, and it is yours. Each step below is shown on the studio's own screen.

1
Step 1: Say it
One sentence is the whole brief: 'Snake, with a high score.' Foundry shows the price before you build.
- As you type, Foundry reads the request and shows its price: a small app, an app with lists and records, or a big app.
- It says so before you build when a request needs something a browser app cannot have, such as its own server.

Step 2: Foundry makes it
The AI plans it, writes the code, then tests the app in a real browser and fixes whatever fails.
- Foundry plans the app and writes a checklist of what it must do, then writes the code.
- Chrome taps and types through a test of every item on the checklist. What fails goes back to the builder, and the build page shows every step as it happens.
- If you ask for it, Foundry also runs its checks on your own phone or computer before the app is published; you can skip that when it comes.

Step 3: It is yours
It appears under My apps at its own private address. Open it, install it, change it with another sentence, or share a link.
- Only you can open it until you share a link, and you can revoke a link at any time.
- Download it as one file that runs with no internet, or as its source. A build that does not end in a working app gives its tokens back.
