This is a service to help communities propagate to other instances and help with discovery of communities. So far tested and working with PieFed & Lemmy Instances - I suspect it should work with Mbin, but need to test it (Any Mbin Instance volunteers?)
Anyone is free to add their community to the list, but only admins can add their instance to receive communities.
This tool is designed to be simple to use, not requiring fiddling with your instances DNS unlike Lemmy-Federate. Verification for authority to register your instance is done via a message that checks to see if the person confirming is an admin account. It also back-propagates, so on joining your instance will subscribe to all previously added rather than only new ones going forward.
This is my first time launching a service like this, and as such it may not work flawlessly - please share any feedback or suggestions.


Other than DNS login, how does this differ from lemmy federate?
My number one concern is that now there are two services providing what appears to be the same service, some instances will use one of them, some will use another. That could harm community discovery unless we sign up to both.
Is there, for example, better piefed support?
Signing up for both causes no harm and provides redundancy.
This one offers adding communities through the Threadiverse via messaging the bot. Meaning it can be used completely independently of ever visiting the site straight from your app of choice.
It also has a PieFed plugin (thanks to the wonder @wjs018@piefed.social) in the works that will auto add new comms on any instance running the plugin to the database. Just waiting for a hook to be merged into a future PF update before that can be finalised.
