Someone had the good idea of maintaining a list of Unearthed Arcana content all in one, easily accessible place here, including things that aren't subclass or race options. I'll add older and older content until I get bored or add all the 5e UA content. Content will not be added if it (or a similar version) was published before 1 January 2018 and has been has since been published in an official Wizards of the Coast Dungeons and Dragons publication.

I appreciate you doing this. (I posted a feedback thread a while back requesting a list of active playtest on DDB).

Dont forget Eberron races.

I was gonna include Eberron races, but those were posted before the cutoff deadline and have since been published in Wayfinder's Guide to Eberron. In the introductory paragraph at the top, I explain: "Content will not be added if it (or a similar version) was published before 1 January 2018 and has been has since been published in an official Wizards of the Coast Dungeons and Dragons publication."

Actually, Races of eberron got a revision mid 2018, and dragonmarks and magic items of eberron came out shortly after. All are still in active playtest (free, in addition to being part of WGtE) until rising from the last war is published.

Oh that's so good to know! Thanks for letting me know, and for providing links! Somehow I missed those.

This is a great compilation! Are you going to include the new UA?

Thank you! If I include new things, it would only be things that have been officially retired. In other words, things that aren't in the Live Archive.

EDIT: But I'm lazy so we'll see if I get around to it.

Sidekicks were released in the essentials kit - the one with icespire peak
