I’m interested in setting up my own instances for Lemmy, Mastodon, and Matrix.
Can I use the same https://domain.tld for all of them without any subdomains?
For example:
[email protected]
[email protected]
[email protected]
Will this work across all of my self-hosted instances, or do I need to append a subdomain for each, e.g., [email protected]?
Matrix (or even easier XMPP) can coexist on the same domain with Lemmy or Mastodon, but with two ActivityPub services that is AFAIK not possible.
