Not in the same way, no.

Most of the fediverse is open to all by default and the control admins have is to create a block list of instances they’d rather not federate with. With Peertube it doesn’t federate with anyone until admins on both sides add each other to an allowlist.

One thing that took me a looong time to realize is that Peertube federates weirdly - it’s all under control of the instance admin, not it’s users. Admins decide which instances federate with each other and then all the videos are copied between instances that have agreed to federate with each other.

But there’s no way to see this in the UI, as an ordinary user!

So it’s all super fragmented. Discoverability is atrocious, even by fediverse standards.

If you look at https://instances.joinpeertube.org/instances?sort=-totalInstanceFollowers then that’ll help you find a well-connected instance. Then post onto that one.

If I were blind I’d prefer it if the app just hid all image posts from me. The alt text, when it exists, is going to be trash most of the time anyway.

If you ever need to move instances, go to https://sh.itjust.works/settings and export the settings. Then in your new instance, import the settings. You’ll be following all the same communities as before, same blocks, etc. Settings exported from Lemmy can be imported into PieFed too.

The real bummer is when you invest a lot of time and effort into creating then building up a community on the wrong instance. You can just make a new comm and tell everyone to follow it but making this kind of moving more high-fidelity is high on my list.

PieFed does this.
