RSSHub

A local-first budget app that syncs through a server you run. Open it and create the password that encrypts the budget; the files stay on the server volume.

A virtual whiteboard for sketching hand-drawn-style diagrams. Drawings are kept in each visitor's browser; nothing is stored on the server.

A self-hosted RSS reader. Open the page to finish setup; feeds refresh on a schedule, and the SQLite database stays on the server.
