Reddit Sync will have a full page sign up for his new app, Lemmy Sync, when you open the app on June 30th (also kbin support coming!)

Correction: the pop up for Lemmy should start to appear sometime this weekend

Also apparently confirmed in discord that kbin support will be coming:

Kbin is a different software.

Ah, thank you

But kbin is compatible with Lemmy, as it's also federated via ActivtyPub. Kbin also supports microblogging and can see content in Mastodon.

It also includes microblogging so it's like a mix of lemmy and mastadon (and federates with both)
