sceneNZBs for German content. Will have everything you need :)

If you are using Radarr & Sonarr and want to prefer German DL (Dual Language, German + Original) releases I have a guide for that: https://github.com/PCJones/radarr-sonarr-german-dual-language

Also since it looks like you are new to using the Usenet, I have a German beginners guide: https://github.com/PCJones/usenet-guide/

what you need is the indexer, usenet servers all exchange the same feed which means if something was never posted no one would have it. the usenet servers do not specialize in one particular thing.

In my humble experience, some indexers have been better for non-english content than others. Some notes I have been taking while reorganizing a library:

• SceneNZBs is good for German new content and dual audio or subtitled content, but not as good for rare german movies as I was thinking (specially if you want high quality)
• nzb.su has surprised me being the best indexer so far to have a wide scope of international content. Much better then the others. (I got into almost every single one except for Planet, Ninja, Dog and the 2 that don't like to be known)
• DrunkenSlug has some good quality content too, it came in second during this reorganization.
• Miatrix (!) AltHub, abnzb, Finder and Noob sometimes have some old European and Asian content with good quality that I couldn't find on DS. They shouldn't be ignored for those searching for Sandinavian, Iberian, Italian, German, French and Eastern European content. Even Stars69 sometimes found stuff that the better known indexers didn't. Try to have those as backup free tiers.

Everybody keeps talking that dog and ninja are great for international content (alongside with su) but I didn't test em due to lack of invitations (Ninja is opened today, don't miss it!).

If you are looking for more specialized (less mainstream) content, you shouldn't regret .su
