Seeking a Comprehensive List of ActivityPub Platforms Sorted by Total Monthly Active Users

[davy_jones@lemmy.dbzer0.com]

I'm looking for an up-to-date, comprehensive list of all ActivityPub federated platforms, sorted by the total number of monthly active users across all instances. Similar to Fediverse Observer’s list but for platforms instead of instances using the platform. Does anyone know of one?

"By platform" is a fuzzy request given the interoperable nature of the fediverse. This list is broken up by software, so Lemmy/PieFed/mbin are listed separately even though their users share and interact as if they were all on one platform.
