PicoLimbo is a lightweight limbo server written in Rust, designed primarily as an AFK or waiting server. Its core focus is on efficiency by implementing only essential packets required for client login and maintaining connection (keep-alive) without unnecessary overhead.

When idle, PicoLimbo uses almost no resources: 0% CPU and less than 10 MB of memory, making it extremely lightweight.

While not aiming to replicate every Minecraft server feature, PicoLimbo supports all Minecraft versions from 1.7.2 through 1.21.8, excluding snapshots, with only 28 implemented packets covering over 46 different protocol versions or 74 Minecraft versions.


Highly Configurable

Customize your server using a simple TOML configuration file, including welcome message, spawn dimension, server list MOTD, and more.

Built-in Proxy Support

Seamlessly integrates with major Minecraft proxies:

• Velocity (Modern Forwarding)
• BungeeCord (Legacy Forwarding)
• BungeeGuard & BungeeGuardPlus authentication

Wide Version Compatibility

Supports all Minecraft versions from 1.7.2 to 1.21.8 natively, no need for ViaVersion or additional compatibility layers.

Ultra-Lightweight & Highly Scalable

Uses 0% CPU while idle and under 10 MB RAM, enabling thousands of concurrent players thanks to Rust's asynchronous runtime and efficient design.
