Being able to post/interact on Mastodon via Kbin is amazing. Kbin is really the only fediverse account you need as it has access to Lemmy and Mastodon. Perfect for digital minimalists to have an all-in-wonder website to access the fediverse.
I hope the server-side of kbin can get even better in the months to come, because for some things I really like it more than Lemmy, but trying to selfhost it some months ago on my Raspberry Pi 3 was a failure.
I mean, I was able to set it up, it’s a PHP app, it ran … but it was so incredibly slow, like I had to wait 20 seconds at times to load any page (post, community, home, etc). Sometimes the server required so much time to handle requests (more than 60 seconds!) that they failed (especially signup or login requests. By contrast, the Lemmy backend runs considerably smoother, probably because it’s written in a proper compiled language (Rust). You can see the performance tests I did with kbin at the time if you’re curious: https://codeberg.org/Kbin/kbin-core/issues/2#issuecomment-871332
Federation wasn’t working at all btw, so I can only imagine what would have happened if it actually was to work (altough it seems that was a different issue, unrelated to the server slowness).
