https://www.curseforge.com/minecraft/mc-mods/mmogs-cheat-menu This mod is on curseforge too! This is for only 1.20.1 and does not work in public servers. It is client sided but I put in safeguards so that you cant cheat in servers without the mod installed. You can still join servers with it on but it doesn't work.
This mod has several features and hacks such as:
Gamemode swapper in no cheat worlds Dimension swapper without portals Turn invincible Turn invisible No hunger Spawn 500 tnt Clear inventory with no cheats Super speed And many more!
