TrueVanilla.org is a server intended to test the limits of vanilla Minecraft servers. We are the only public, non-whitelisted vanilla server without a pre-established community currently running on 1.18.1 There are no gameplay-altering, cosmetic or optimisation plugins just unmoderated vanilla gameplay.
TrueVanilla started off without any modifications to the game at all although within a couple weeks the server was unplayable and constantly crashing due to overuse of packet-based movement hacks. In order to keep the server playable we run a custom patch which prevents extreme abuse of hacks like timer. This was implemented to preserve the vanilla ideals of the server, instead of simply installing a full anti cheat plugin.
