Where it goes
Is Debugify required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.
The source does not explicitly classify this release as client-only or server-only.
What else does Debugify extension 'publishMods' property 'version' need?
Debugify extension 'publishMods' property 'version' on 1.21 Fabric. Every mod below is checked against that same setup.
Install YetAnotherConfigLib, Fabric API, YetAnotherConfigLib (YACL) first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match. 2 come through another mod in the chain.
2 extra mods were pulled in by other dependencies. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

What if I want to enable some bug fixes, but not others?
Debugify has a configuration GUI accessible by Fabric's Mod Menu. If you don't want to it, there is always the configuration file located at .minecraft/config/debugify.json

Client, or Server?
Debugify includes many fixes for both the client and server (all server fixes also apply to client). So you should definitely use it on both.
Can I include this in my modpack?
Yes! Of course! I even added a little feature in the mod for you! The constant updates may be exhausting to maintain, so I added a config option that defaults new bug fixes to off, until you get round to looking at it.
