That’s odd, I’m surprised Rossman didn’t upload it to that app store.
Well, in the meantime you can get it directly from https://grayjay.app/. Should also be the first result in google, if you want to search yourself instead of trusting a randomly provided link.
Is Grayjay open source? I can’t find it on f-droid.
No. It’s got a “source available” license allowing only non-commercial use, and revokes the license for anyone who tries to sue them.

It is in FUTO’s F-Droid repo that you can add.
