ModGate
ModGate, a Fabric mod, checks on join that every connecting player has exactly the server's required mods at the right versions.
What it does
On a server, ModGate compares each player's installed mods, including their SHA-256 hashes and versions, against a list the server owner sets. A player who joins without the required mods, or with extra mods the server does not allow, is shown a custom disconnect screen that lists each mod with a checkmark or a cross and its current and required version. Players who lack ModGate on the client are kicked automatically after 10 seconds.
The mod is meant for servers that need strict mod synchronization. The server configuration can be reloaded without a restart, and server operators with level 2 permissions or higher can run the modgate commands to reload the configuration, export the current mod list to a config file, import one, or list the required mods. Both the server and every player need the mod, since it is a client and server install. It depends on Fabric API and runs on the 1.20.1 and 1.21.1 game versions, with the latest Fabric file, 1.4.6, built for 1.21.1. It is released under the GNU General Public License v3.0 or later and is not open source.

Use cases
Modpacks on dedicated servers
A server that runs a fixed modpack can use ModGate to make sure every player matches that pack before entering the world.
Who it’s for: Server owners who run a fixed set of mods and want players to match it exactly. Players on such servers need the mod installed on their client to avoid the automatic kick.
