Very cool - played around with it, and it seems quite featured, and my test podcast worked!
I really appreciate the local-first, self-contained but very portable architecture, with an optional server connection to handle CORS and index and whatnot; that's a really solid approach.
Hopefully this isn't too annoying, but I saw you open-sourced what looks like the backend, do you have any plans/interest to open-source the front end as well, for people who might want to self-host?
Yay! And not at all annoying. No plans to open-source the frontend at this stage but I'll keep the request in mind. Btw, that backend was part of an earlier abandoned infrastructure attempt. Still cool code imo, but no longer running on it.
