PointZero
by ergghur
PointZero is a Fabric anti-cheat mod that checks the mods and resource packs a player runs against a server's allowed list before the connection completes.
What it does
On a server running PointZero, a joining client's mods are compared with a whitelist kept on the server. Hashes of each mod file are validated with SHA-256, so a renamed or altered file does not pass. Connections from players whose active resource packs or mods do not match are refused, and the check waits and times out with error messages where a response never arrives.
The server side creates an allowed-mods folder on first start, where the permitted mod files are placed. Hashes are cached at startup so later joins are checked faster. Server operators can use their mods through an OP bypass. The mod needs Fabric API and runs on client and server, so every player and the server both need PointZero installed. It is published for Fabric only, for 1.21.11, and the code is all rights reserved, so it is not open source.
PointZero is published for 1.21.11 alone, with 2.0.0 as the latest file, dated 2026-03-08 on the alpha channel. The first file went up on 2026-03-07.
Key features
Server whitelist
Only players whose client mods match the server's allowed list can join, keeping out unlisted modifications.
SHA-256 hash checks
Each client mod is verified by its SHA-256 hash, so a changed or replaced file is detected at login.
Resource pack checks
The active resource packs of a joining player are inspected as part of the same validation.
Cached startup hashes
Hashes are computed once at server start and cached, so repeated joins avoid recalculating them.

How it compares
Defixus Anti-Cheat is a Fabric mod for 1.21.4 – 26.3 that also runs on client and server, under All rights reserved, so it is not open source. Remember Url Hashes covers 1.21.1 – 1.21.8 and is client-side only, released under the MIT License, so it adds nothing on servers. XaiAC is client-side only for 1.21 – 1.21.11 under the Apache License 2.0. SentinelClient targets 1.21.8 – 1.21.9 and needs the server, with the client optional.
