• Source: [1] Fediverse-Observer, [2] FediDB

Notes:

1. Threadiverse is Piefed, Lemmy, and Mbin. Fediverse only accounts for listed software [12], not the other [117] software tracked by Fediverse-Observer.
2. Fediverse-Observer provides daily MAU back to 20221130. FediDB only provides a current snapshot (snapshot within the last 15 minutes, no time series data) and doesn’t track all software.
3. FediDB seems to use unclear math to get their counts and overestimate the MAU on most software (see previous post, if interested in learning more).
4. Weirdly Loops has a ~3 week gap in data about a year ago (should be last week of gap).

Takeaways:

• Positive Daily Growth (last 7/7 Days): Piefed
• Positive Daily Growth (last 6/7 Days): Bookwyrm
• Weekly Growth (>10%): Piefed
• Lemmy appears to still have a relatively large server (~4k MAU) jumping in and out.
• Loops seems to be close to stabilizing after drop-off following large gains. Possibly stabilize soon around 2x what it was 3-months ago.
• Overall middling week for the Fediverse.

Edit: Changed some formatting and clarified some wording.
