I’m not sure I completely understand the differences. Are they seperate or somehow connected?
Also I’ve read you can view kbin instances on Lemmy somehow. How does that work if they’re two different things?
I’m using Liftoff is it somehow possible to view kbin instances on there?
They are two separate projects with similar goals (implement a Reddit clone). They both use the activitypub protocol, so they can generally interoperate. Other activitypub based services, such as mastodon, can also interact with either Lemmy or kbin, but in a more limited and clunkier way.
Lemmy was started first so there are more servers and more users, kbin is more recent.
