I can recommend https://git.fiatjaf.com/song, it's been working great for me, although it needs a little more work (and maybe some colors).
The love about that decentralization ends for most at the choice of their sourcecode hosting platform #github (owned by Microsoft) 🙄.
I can wholeheartedly recommend https://codeberg.org as an alternative, the underlying tech can also be selfhosted. It just has one huge problem: you get near-zero activity because everybody is too lazy to register 🥴.
