Welcome to the SRD JAM!

This is a jam for creating SRDs or hackable TTRPGs. It can use any mechanics you like and can be priced in any way you like. You are free to work solo or in a team. It can be anything from a plain text document to a fully published print because we don't discriminate. No theme. No limitation. There will be no ratings and no judging because everyone is equal here. Well that's pretty much it so get ready to design!

It is helpful to submit SRDs you have already made but making new ones is very much appreciated.
