No Cheats
A simple mod that disables the use of any cheats in a singleplayer world
About this Mod
A simple mod that disables the use of any cheats in a singleplayer Minecraft world. This disables all commands and also disables the "Open To LAN" functionality. As future versions comeo out, I will make this mod compatible with them. For the time being, however, the only version compatible will be 1.21.11.

No Cheats server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.
Is No Cheats compatible with fabric?
No Cheats officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with No Cheats – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if No Cheats consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
