Are these Discord invite links still active?
Yes. disdex re-checks every invite link continuously, so expired or dead invites are detected and pushed down automatically. The Undertale invites shown here were confirmed working on the most recent check.
How do I add a Undertale Discord server to disdex?
Paste the server's invite link into the “Add” box at the top of any disdex page. We fetch it right away and it joins the listing once indexed — no account or signup needed.
Do I need an account to browse Undertale servers?
