Deployment
Download App
Download any app as a standalone zip. The downloaded app runs completely offline — no Capsul server required, no account needed, just open the HTML file.
How to download
- 1Open your app in the Builder.
- 2Click the Download button in the toolbar.
- 3A zip file is downloaded containing
index.html. - 4Open
index.htmldirectly in any browser — no server needed.
Standalone database
Downloaded apps use AlaSQL (a pure JavaScript SQL engine) instead of the server-side SQLite. Data is saved to the browser's IndexedDB automatically, so it persists across page reloads on the same machine.
✓ What works
- • All CapsulDB API calls
- • CREATE TABLE, INSERT, SELECT, UPDATE, DELETE
- • Transactions
- • Persistent storage via IndexedDB
- • Works fully offline
- • Works on
file://
✗ What doesn't work
- • CapsulAI (throws clear error)
- • Shared data between users
- • Cross-device sync
Exporting your data
From the Builder, you can export your app's SQLite data as a JSON file via the Data Export option. This is useful for backing up data before downloading or for migrating between environments.
