jointhefediverse.net seems to be a commonly linked resource for directing people to join the Fediverse.
Curiously, it does not list Lemmy under the list of Reddit alternatives. Their GitHub README explains why.

Yeah I’ve heard of that, maybe I should look at it more. Hopefully the Lemmy codebase is fine though. I’m just saying it’s possible, even if perhaps unlikely, that something could be lurking in the code which nobody has discovered yet. The XZ Utils backdoor was well-hidden and happened to be discovered, but maybe malicious code isn’t always discovered.
