How it works
Paste an invite link or just the code. The checker asks Discord’s public invite API about it, the same way the Discord app does when you open a link, and shows everything it returns: the server’s name, icon, banner, description, member and online counts, boost count, verification level, and server features like Community or a custom vanity link.
It also tells you whether the invite expires or has a use limit, which channel it drops people into, and whether it is a vanity link. If the invite is dead, you’ll see that too, so you can replace it before it costs you members.
Server owners use this to check the links in their bios, ads, and listings. Members use it to see what a server is before joining.
Questions
Why does my invite say it is invalid?
The invite was deleted, reached its maximum uses, expired, or the server was removed. Create a new invite in Discord with “Expire after: Never” and “Max uses: No limit”.
Does checking an invite join the server?
No. It only reads the public preview Discord shows for every invite. Nothing is joined and the server owner isn’t notified.
What is a vanity invite?
A custom, permanent link like discord.gg/yourname. Servers unlock it at boost level 3, and Discord Partner or Verified servers get it too.
