PicoMC Modern Minecraft. Tiny footprint. ⚠️ PicoMC is in early development. Expect bugs, and always back up your server before installing. PicoMC is an optimization plugin built specifically for LeafMC 1.21.11 . It automatically applies hundreds of carefully tuned settings and dynamically manages server resources in real time. The goal is to run modern survival Minecraft on as little as 512mb–1gb RAM for 1–5 players. Other versions may load but won't achieve full performance gains (such as PaperMC, Purpur, or older and newer versions). Still real Minecraft Other projects achieve low hardware usage by rewriting Minecraft from scratch in C or other languages — impressive technically, but you lose everything. No plugins, no mods, no familiar behavior. PicoMC runs on LeafMC which is built on Gale → Purpur → Paper → Spigot → Bukkit. That means: Any Spigot, Paper, or Purpur plugin works alongside PicoMC Vanilla clients connect — no client mods needed Full survival gameplay — nothing gutted, just optimized What's in v1.0.0-beta Automatic Config Optimization On first startup PicoMC backs up all your original configs to a folder in your server root, then replaces them with optimized version
