LightSirius

LightSirius Anti-Cheat is currently available for use with only the "noweb check" feature. For now, this feature can be used for free. In the future, I might add more checks to the free version. Additionally, perhaps in the coming days, I could release a paid version and include more control mechanisms. LightSirius has been coded to be lightweight and fast.

If you have any errors or suggestions, you can report them through our Discord server.
