Next to Mastodon.world and Lemmy.world I am also running Calckey.world. This was running Calckey, a Misskey fork. That was re-branded to FireFish (that’s the danger of running sites with the software name in the URL… :-) ).
Unfortunately due to circumstances the FireFish software will no longer be maintained. Therefore I was looking for another Misskey fork that could replace it, and I found Sharkey. This looks really nice.
So being who I am, I registered https://sharkey.world and installed it. It still needs some configuring and branding, but it works and you can use it! (As you will see it currently uses the Calckey.world branding)
I will write a brief how-to on migrating from Calckey to Sharkey and hope the calckey.world users will migrate.
I’ve never used it but it is my understanding that it pretty much the same thing with more functionality.
It’s not. It’s a different thing with different functionality. You can’t follow hashtags and it doesn’t work properly.
