Aside from project homepages and issue trackers, and comments made on the fediverse, the [SocialWG has a list](https://www.w3.org/wiki/Socialwg/ActivityPub_network) of projects they hoped would implement ActivityPub and links to issues where it's discussed. Also, there is an [implementation report on ActivityPub.rocks](https://activitypub.rocks/implementation-report/). @Mayel from Social.coop created a [web spreadsheet of AP apps](https://ethercalc.org/fediverse-stacks) and their characteristics. More projects using AP are [profiled on We Distribute](http://wedistribute.org/) by Sean Tilley and his team. There are boards for discussing a range of [AP implementations on the SocialHub forum](https://socialhub.activitypub.rocks/c/software/14). [Alternative.to](https://alternativeto.net/list/5696/activitypub) has a list of AP servers and client apps. The [ActivityPub tag on GH](https://github.com/topics/activitypub) is also a way to discover projects experimenting with AP.
