Flappy Anticheat

Flappy Anticheat is a cheat protection system for Minecraft servers that I'm developing. Currently it operates on an event-based model, but a transition to packet processing is planned for the future. I'm making every effort to eliminate false positives and potential protection bypasses. The main goal of the project is to create a highly customizable anticheat where all messages and checks can be customized through the configuration file.

Supported Versions

The system should work on Minecraft versions from 1.8 to 1.17, however full testing has only been conducted on 1.13 and 1.17. Version 1.18 may function correctly, while 1.19 is not yet supported.
