Instead of just searching the specific name of a sub what if I want to see every sub that’s contained within an instance such as lemmy.world for example no I’m not part of lemmy.world but as part of the instance I’m a part of I can see every sub under it in a neat list can you only do that if you’re part of the instance?
That’s… Tedious
An easier way is to use http://lemmyverse.net/communities
Set your home instance using the home icon on the right
Select only the target instance with the instance filter
Now you can see only the target instance communities, and clicking on them will open them on your home instance
Also, on most instances NSFW communities are listed only if you are logged in and enable such content on your profile.
So is there a way to see those? A good example is lemming.online, which you can’t sign up for. The only alternative I’ve found is browse by new and just wait to see what communities pop up.
Lemmy isn’t focused on everyone seeing everything but on keeping corporate interests and power tripping admins out. The idea is to encourage as many people as possible to run their own instance of Lemmy both to share the infrastructure costs and limit the power each instance holds. Keeping hosting costs down is why instances don’t pull from communities nobody is subscribed to.

So, from what I can tell anyways, it does seem like the original answer is what you’re looking for. Each instance has a list of its own communities that you can see. You can also see a list of other instances that are federated to an instance by browsing to /instances (ex. https://lemmy.ca/instances shows all the instances lemmy.ca is federated with as well as which ones are blocked). As far as I know, there is no way to see a list of all communities from all federated instances. There are some external sites that seem to have these sorts of lists like https://lemmyverse.net/communities
