I dont think there are any “main” instances. That’s kind of the point.
I used “main” in terms of popularity.
then at the moment lemmy.world is the largest one. Its run by mastodon.world admins and is still relatively oerformant and reliable given its size. Lemmy is growing rapidly and that could change very suddenly any day now.
https://join-lemmy.org/instances sorts instances by Popular and Recommend.
This is more of a support question, related to using Lemmy. Please see the sidebar for additional resources.
It also runs afoul of rule 1 as it’s not a particularly open question.
You might enjoy poking around here:
