I only need to send sign up and password reset emails for Jellyfin, I don’t need to receive any emails back.

Grist is a selfhostable alternative to Airtable

You can selfhost Standard Notes. The notes are encrypted client side before they reach the server.

I’ve been using OwnTracks for a while and it works really well.

You can use Subtify with Navidrome to import your playlists. It matches your Spotify playlists with your local music.

The work around did work however you needed to download an older archived version that was unpatched.

I setup a Lens so that if my query contains a single letter ‘r’', only Reddit results will be returned.

No, this is a bookmark software. You can probably use JDownloader for this to scrape a URL for downloadable content, depending on how the site you use is formatted.

Just because your personal computer isn’t Windows, plenty of servers that contain your data are.

A small whiteboard on the fridge perhaps?

If you need to throw in the towel on email self-hosting, don’t be ashamed. Mail servers are one of the more difficult projects to run. If you do end up outsourcing this, I recommend SendGrid, it’s reliable and free.

I have run Jellyfin for about 3 years. Plex has a lot of community support and praise so I spun up a test instance. Unfortunately for Jellyfin, Plex is much most reliable for me in pretty much every way. I would love for Jellyfin to keep improving but the switch to Plex just made the media experience so much nicer.
