What if the browser was the server? Go compiled to WASM and SQLite, running entirely in the browser’s tab. No server, no account

I've been thinking about how most personal productivity tools are SaaS for business reasons, not technical ones. A time tracker, journaling app or habit tracker has no reason to store your data on a remote server.

WASM changes this. You can compile a backend in any language and ship it directly to the user's browser.

SQLite can run there too, storing data persistently via OPFS, a filesystem API the browser now ships with. The whole thing is delivered via a URL and runs entirely on the user's machine. No server, no account, no subscription.
