How to use:
The url must be the hostname only, NO SLASHES, like this: lemmy.dbzer0.com, don't use https://, don't append a slash afterwards (lemmy.dbzer0.com/), only the hostname including the subdomain if it has it (in this case, lemmy).
If the instance has blocked the IP address from the server, or it is stuck and its API is not working correctly, it returns "Not a Lemmy instance" (I am too busy to fix this right now).
If the url is not formatted in a way it can process it, it will say Invalid URL. Better processing can come in the future. I won't be updating it now.
- URL: https://federation-checker.vercel.app/
- Source code: https://github.com/lemmygod/federation-checker
In the backend, it just scrapes https://fba.ryona.agency/?domain={url} and uses the api https://{instance}/api/v3/federated_instances
PRs welcome.
Honestly it works better when deployed locally in a development environment. I think Vercel's IP address is just blocked by cloudflare and other blacklists that stop automated stuff? Idk. Can check back in a few days.
And I said, the purpose is not to link. Linking is not the purpose. It has nothing to do with the purpose.
The purpose is to interact. This tool checks if you can interact. Sometimes you can, sometimes you can't, simple as that. If you want to interact but the instance you're considering can't, then you put it in your back pocket and keep looking.
Yeah bad example. It's more like you have a sniper's rifle and you wanna see if you can pop a head or whether that head is vaccinated against the exact brand of bullet that you're carrying.
