Everything your server needs

From first boot to a running multiplayer world — ZBB handles it so you don't have to.

⚡

Auto-Healing Watchdog

Detects crashes, zombie processes, and TPS lag spikes. Exponential backoff restarts keep your server alive — even when you're offline.

Instant Public Tunnel

Integrated Playit.gg agent gives your server a permanent public address. No router config, no DynDNS — friends just type the address and join.

Playit.gg · No Port Forwarding
☕

Smart Java Management

Reads bytecode from your server JAR to pick the exact Java version. Downloads the right JDK silently — never touches your system installation.

Java 8 · 16 · 17 · 21 · Auto-detect
🧩

Modrinth Mod Browser

Search, install, and update mods directly from inside ZBB. Per-server mod lists, version picker, and one-click update checker.

Command Sanitizer

80+ safe Minecraft commands on an explicit allowlist. Shell injection, pipe operators, and dangerous flags are blocked before reaching the JVM.
