I have a library bigger than yours, I’ve tried many apps on f-droid an year ago and so far the only that seems to be able to handle my library at all is Music Player Go.
It takes like 15 seconds to open, but after opening it works fine, however, it doesn’t support replay gain.






Depending on how you define “self-hosting”, I may qualify at that.
I’ve hosted my email on a remote VPS myself. I have not hosted the machine in my apartment.
I used postfix + dovecot + mysql stack, I have to admit it was the hardest thing I’ve ever configured and I’ve hosted a lot of services in my life.
In the end I ended up switching to the free service that came with the domain became no matter what I did and how compliant I was to dkim and SMARC and tkip (I’m probably butchering the name here, it’s been a long time) outlook accounts kept sending my emails to spam, everything else worked fine, even gmail, but DAMN Microsoft and how much I hate that company managed to fuck over me one final time even after years after I switch to Linux. I tried everything even the form to remove my email from spam.
Tl;Dr hosted email on a vps but couldn’t get past outlook spam filters
