On October 11th these two commits where made to the repo:
this will be my final release, glad to have contributed since 2011 to some fediverse stats, https://fedidb.com/ is a great resource with more interest
this software is no longer developed
Sad to have lost such a great resource.


You’d think it’s straightforward and additive. I added up all their listed instances for a couple different softwares. The math was wrong and overestimated the MAU count. I checked it a few times across a couple weeks. Couldn’t quickly figure out a pattern to how the math was wrong each time.
Maybe they fixed it in the last ~6 months, but I wouldn’t count on it. I believe it’s the same Dev as pixelfed and loops. So, not sure they’ve done any work on fedidb in years (to my knowledge, they’ve focused on Loops and Pixelfed).
Edit: to clarify, adding the MAU of all their listed instances for a particular software was lower than the total MAU they reported for the software.
Edit 2: Just checked their Piefed listings and it’s still wrong. Fedidb states: ~7.0k, actual addition: 6858 MAU.
Have you contacted them about the discrepancy? Ideally FediDB could just become the new Fediverse Observer.
Missing out on accurate data about Fediverse growth would really suck. 😕
I just confirmed the problem still exists and messaged them via mastodon about it.
Probably didn’t let them know originally because I didn’t have a mastodon account at the time and already had a good option (fediverse-observer).
