Our Dungeon World Compendium provides all the useful information you need to get started with playing a game of Dungeon World. Classes, Moves, Spells, Equipment, and all of the Rules are available for you here.
We've got the beginnings of a Pathfinder SRD going, and we're working to improve it every day. Pathfinder Spells, Pathfinder Items, and the Pathfinder Bestiary are all yours to delve.
Access all of our Starfinder Roleplaying Game compendium entries, such as Alien Archive, here.
DramaSystem gives you the tools to create emotionally compelling narrative through interpersonal conflict. Explore the rules here.
You can quickly access the Compendium right from inside your game while playing on the Roll20 virtual tabetop. And if you're using a compatible Character Sheet, you can just drag-and-drop spells, items, or monsters right out of the Compendium and onto your sheet to fill in the details.
The Compendium features a search bar at the top of the screen that you can use to search for nearly anything -- a spell, an item, a monster, a class, even a condition, an attribute, or any other rule you might need to quickly reference during your game.
Beyond just searching by keyword, though, you'll find that the Compendium features an advanced search capability unlike anything currently available. Want to know all 5th Edition spells available to the Wizard class by level? Or how about all 5E Monsters by Challenge Rating? Or get even more specific -- how about all 5E Monsters that are Monstrosities and can cast one or more spells?
Every page is fully optimized to render on mobile devices such as phones and tablets so you can take the rules to your in-person game on the go.
The Compendium is a resource that the whole community can freely use. Anyone can apply to help edit the Compendium and keep it up to date, and all of our data is freely available in JSON format. Future tools can build on top of this data to create even more engaging experiences for the whole community.
