Suggestions? GitLab/GitHub? I don't really use Google sheets and these links actually just come out of my book marks (I've got a 'Self-Hosted > Authentication' folder) and years of bookmarking.

Maybe one of the awesome-<x> lists?

one of the problems with the "awesome" lists is exactly that: it's just one huge list, and it's hard to tell what's what.

maybe just a gist with a markdown table? or maybe expanding on this:

https://en.wikipedia.org/wiki/List_of_single_sign-on_impleme...

... if you have the courage of dealing with Mediawiki tables (although the WYSIWYG editor has improved kind of enough to make that workable nowadays...)

hmnnn yeah the discoverability problem is a bit of an issue with the gist, and wikipedia seems better but that page is kind of right but not quite...
