I’ll start with one of the most useful singular list of lists on the internet.
https://github.com/topics/awesome
“An awesome list is a list of awesome things curated by the community. There are awesome lists about everything from CLI applications to fantasy books. The main repository serves as a curated list of awesome lists.”
Just about anything you can think of is within this list. Enjoy!
PS: Thank you mods for your work moderating submissions. The quality and relevance of posts here is refreshing. This has to be my favorite community on Lemmy.

I use this Android benchmark website whenever a sibling asks me, “what phone should I get?”
It’s not a precise comparison. (In fact, it rates different carrier software running the same LG G710 phone hardware as anything from 7,000 to 8,000.) And it reminds you of its imprecision several times.
But some phones made today benchmark like they’re seven years old. And the site helps you avoid those egregious cases.
AlternativeTo.net
The name is pretty self-explanatory, but even if you don’t know the exact program you’re looking for, the search tool can find you programs based on a description like, “photo editor” or “markdown editor.”
It’s one of the first places I go when looking for software. Especially open source software.
