It'd be nice to not be pushed into subscriptions or downloading an app to make a mobile website readable.

And these usually take up the first page of results, so I can't help but feel that the plain, actually usable websites are buried. What else do you guys use?

There's one that some bot was promoting recently. If someone comes along and suggests a site that rhymes with "sword tomb", I'd skip it. Spambots get fucked.

Freetar is my jam. Minimal, FOSS frontend for U-G; sort of like what Invidious is to YouTube.

Freetar is an alternative frontend for UltimateGuitar. It cool that it's not so annoying. But the mobile experience can be worse than UG w/ adblock, so it doesn't really solve that problem.

But yeah, in general I don't have a great answer. It surprises me that I don't know of any prominent websites that openly share general tabs and lead sheets and don't suck.

Idk about mobile, but there is metaltabs.org (obv if it is specifically metal you are after).

If you like video game music, there's https://gametabs.net/

Or https://www.ninsheetmusic.org/ It's sheet music, but some are workable for guitar.

I recommend actual, physical books.
It helps me keep my practice distraction free.
