join-lemmy.org regularly crawls all active Lemmy instances to keep the instance list updated. Additionally it also collects data from all Lemmy communities. The data is now publicly available in the following git repository:

https://github.com/LemmyNet/lemmy-statistics

Check the readme for details about the available data. Interestingly the numbers are quite different from other websites:

join-lemmy.org fediverse.observer fedidb.com
Monthly Active Users 42.170 36.336 50.063
Instances 512 376 446

Here are some ideas what to do with the data:

  • Recreate the Lemmymap, graphically showing the connections or defederations between instances.
  • Render graphs, which could be added directly to join-lemmy.org (#532).
  • Investigate what is causing the different numbers shown above.
  • Run various types of analysis, like this one done by @malsadev.
  • Build a tool to help users discover interesting and relevant communities.

    42 Monthly Active Users … that’s the final answer to life, the universe and a verything 😋
    … i am surprised, i expected the figures to be in the thousands 🤣

    Edit :

    Seriously now, new standard :

    . https://en.wikipedia.org/wiki/Decimal_separator
    .
    The 22nd General Conference on Weights and Measures[27] declared in 2003, “The symbol for the decimal marker shall be either the point on the line or the comma on the line.” It further reaffirmed,[27]

    Numbers may be divided in groups of three in order to facilitate reading; neither dots nor commas are ever inserted in the spaces between groups

    That is, “1 000 000 000” is preferred over “1,000,000,000” or “1.000.000.000”.

    The official join-lemmy.org page problematically includes Hexbear, which would account for 1,553 of the difference between it and fediverse.observer. The remaining 4,281 difference seems to be several servers not listed by fediverse.observer.

    Those above 50 MAU exclusive to the join-lemmy list are aussie.zone (313), jlai.lu (273), lemmy.wtf (164), and lemdro.id (67), whereas those exclusive to the fediverse.observer list are lemmy.dorfrollenspiel.de (79), lemmy.cafe (72), and fosscad.io (59). If the official list selectively excludes those two (as it does lemmy.world and sh.itjust.works), then the remaining difference would be 3,464, otherwise 3,674. The rest can partly be explained the sum of servers with fewer than 50 MAU, though perhaps one list is updated at a different frequency than the other to explain the rest.

    For the sake of Lemmy’s growth, it’s problematic that join-lemmy.org (as an official platform) features Hexbear, Lemmygrad, and Lemmy.ml so prominently. While I dislike Reddit enough to have not tossed away Lemmy as a whole for its tankies and instead blocked those instances, featuring and recommending the use of extremist instances hurts Lemmy’s image (and Piefed and Mbin by association) in the eyes of potential users.
