Every listing is a public community with a working invite. Pick a category to filter the list above.
Choosing a Open Source server
They span Programming, Gaming, so the tag covers more ground than a single category would. Member count is the wrong thing to sort by on its own — what matters is how many of those members are online when you are. Use the Activity filter or sort by "Most online now" to put the servers that are actually busy at the top, and check the online percentage on each card before you commit to joining.

Open Source Discord Servers FAQ
How many Open Source Discord servers are listed here?
11 right now, with roughly 69,510 members online across them at the last check. The list only includes servers whose invites still resolve, so it shrinks when a community closes rather than filling up with dead links.
How do I know a Open Source server is still active?
Compare the online count to the member count. Anything above about 4% online is a live community; below 3% you are looking at a large list of names and a quiet chat. Both numbers on every card come from Discord directly.
