Ask HN: What are the best open source products you've come across?

The *arr ecosystem of open source apps, which provide me with a full stack of media management. Requests, downloads, storage and streaming of my content to friends and family. The ones I use are:

* Sonarr - Automatically downloads TV shows/new episodes

* Radarr - Automatically downloads movies

* Bazarr - Automatically downloads subtitles for TV shows and movies

* Unpackerr - Automatically unpacks archives for importing by Sonarr/Radarr

* Jellyfin - Media server, streams video to apps or browser

* Jellyfin for Kodi - Addon to stream from Jellyfin in Kodi, a media player optimized for TVs/big screens

* Jellyseer - Lets your Jellyfin users request content

Users request content in Jellyseer, or you can add content manually through Sonarr/Radarr. Once you approve a request or add a show, Sonarr/Radarr interfaces with your chosen content source (torrent/usenet), and sends a matched release to your download client. Once the download is done, it is unpacked by Unpackerr if it's archived, imported into Jellyfin's media folders based on type, Bazarr picks it up and looks for any missing subtitles. The user can now stream the content via Jellyfin.

As for hardware, it is running on a homegrown NAS, running Ubuntu Server, with 18 TB of storage configured in RAID 6, and modest specs (8 GB RAM, medium-end Intel processor and an ancient AMD GPU). Works a treat.

Miss me with that "paying for 20 streaming services" bullshit.

I don't actually like many Open Source "products". I like a lot of Open Source and Free software, but trying to turn that stuff into a product almost inevitably ruins it. Just look at Plex, or NextCloud, or Docker, etc..

When it comes to open source there are lot of such products but I've used AdminJS in my daily work, and it's really good. More tools like, cal.com, Chatwoot, etc.
