Sources

Aside from project homepages and issue trackers, and comments made on the fediverse, the SocialWG has a list of projects they hoped would implement ActivityPub and links to issues where it's discussed. Also, there is an implementation report on ActivityPub.rocks. @Mayel from Social.coop created a web spreadsheet of AP apps and their characteristics. More projects using AP are profiled on We Distribute by Sean Tilley and his team. There are boards for discussing a range of AP implementations on the SocialHub forum. Alternative.to has a list of AP servers and client apps. The ActivityPub tag on GH is also a way to discover projects experimenting with AP.
