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.


Most countries in the world use decimal comma IIRC
Number of countries using comma may be more, but as India and China and Nigeria use dot, the number of dot user people may be higher.
