Resources For Common Games on GP

I decided to make this thread so that we can have a compilation of resources for games that are commonly played on GP. We can include things to help players learn the rules, create their own content, etc. If you have suggestions for things to add, post a link and what that link is useful for!

The two first spoilers don't seem to work...

For any stuff DnD 5e, 5etools is very useful, as is DnDBeyond. Although on the latter, you'd have to buy the books you want access to.
I think they are just empty.

Yes, I think he's using placeholders to accommodate links that people share on those topics.

Dice Cloud, a cloud for making and managing digital DnD 5e character sheets.
Tools to autofill said Dice Cloud sheets.

This is correct :)

5etools? 5e Point Buy Calculator? Or are we sticking to official sites?

Any resources (as long as they're PG-13) are good with me :)

System Reference Document for the Fate system(s). Also includes some of the rules from games built on Fate such as Venture Cities and Atomic Robo, although those aren't entirely complete. There's a section for interesting Fate related reading material too, like the very useful Book of Hanz.

HUGE list of Fate Core stunts, compiled from official Fate material.

Oh wait, can't forget this one. It's like CR ratings, except for Fate Core. The archive itself is a good resource too.

I'm starting to wonder if this is not turning into a 2.0 version of my free games and resource thread...

Also my first thought, kalajel. I think the difference is that this list should be filled with only the most commonly-played games on GP, while your list includes a far broader range.

For pathfinder 2e may I present;
pf2d20pfsrd.com

One can learn the game by perusing this site, but to really play; you must have the books.
The folk at d20pfsrd are quite cool. They share a passion for the game and helping players find the content they are searching for.
They have their own store, frequently publish, and support third party game companies.

Updated to include all of the suggestions thus far. Keep 'em coming!

One for the 5e DMs. I quite like this CR calculator as a quick tool to see if I'm in the ballpark when homebrewing monsters.

A common resource for GP is On the fly battle maps
In short: You write an url that generates an image that you can use with the [.img][./img] option, but check out the documentation for more

example: [.img]http://otfbm.io/D3p-Pur/A1r-Red/G4g-Green[./img] (without the dots)


Then when we want Red moved next to green F4, we change the coordinates for Red to this
