BetterGrim
by CalamityCats
BetterGrim is a Fabric fork of the Grim AntiCheat plugin that adds new checks and reworks several existing ones for server owners who run Minecraft servers.
What it does
BetterGrim is a fork of Grim AntiCheat. Its additions include a NoWeb check, fixes for NoWeb bypasses, a reworked AutoClicker check, new Invalid and Inventory checks, and fixes for tick-based NoSlow bypasses. The NoSlow mitigation resets the item usage state instead of issuing setbacks, which the author describes as safer.
The project runs on proxies such as Velocity and BungeeCord. Geyser and Floodgate need to be installed on the backend server that Grim accesses for Floodgate players, and ViaVersion must be installed on the backend server for Grim to work with it. BetterGrim also supports a proxy that has ViaVersion installed, even when the backend does not.
Installation requires Fabric API. Files target Fabric and cover 1.7.2 – 26.1.2, with 82 release versions. The code is licensed under the GNU General Public License v3.0 or later and is open source. Source code and an issue tracker are public, and the project accepts contributions described in its contributing guidelines.
Key features
NoWeb check
A check that detects movement patterns associated with web cheats, along with fixes for known NoWeb bypasses.
Reworked AutoClicker check
The AutoClicker check is reworked to detect automated clicking more reliably.
Inventory and Invalid checks
New checks cover inventory actions and invalid client packets, extending the detections of the original plugin.
NoSlow mitigation
Tick-based NoSlow bypasses are fixed, and the mitigation resets item usage rather than applying setbacks.

Use cases
Who it’s for: Server owners who want Grim-style checks with additional NoWeb, AutoClicker, Inventory and NoSlow handling. Players do not need to install anything.
How it compares
AutoServer is a server-side only Fabric mod under the MIT License, published for 1.7.2 – 1.21.10, and it manages server startup instead of checking player behavior. PRAXIC AntiCheat is server-side only, open source under the Apache License 2.0, and targets 1.21.1 alone. check client is client-side only, not open source, and covers 1.21.11 – 26.1.2, so it runs on players' machines rather than on the server.

What the author says
If you use a proxy such as Velocity or Bungeecord: - If you use Geyser, Floodgate must be installed on the backend server (where Grim is) so Grim can access the Floodgate API. - If you use ViaVersion, it must be installed on the backend server (where Grim is) ONLY. Grim does not support having ViaVersion installed on…
