Why Server Owners Choose Zircon

No support tickets. No version conflicts.

Your server dictates the mods, shaders, and configs. Players click PLAY and spawn in synced.

Single-Port Multiplexing

Minecraft protocol (25565) and HTTP/REST manifest delivery run on the same single port. No configuring multiple ports, reverse proxies, or complex firewalls.

CurseForge & Modrinth In Dashboard

Search millions of mods directly from both Modrinth and CurseForge inside the web panel with zero API keys required. Click once to install dependencies automatically.

Idle Sleep & Auto-Wake

When everyone logs off, the server pauses JVM execution to save CPU and RAM. When a player hits PLAY in the launcher, Zircon wakes the server automatically before connect.

Live Web Console & Stats

Execute commands, review colorized Minecraft server logs in real time, and monitor server CPU, memory, and tick rates from any web browser.

Automated Backups

Schedule zip backups of worlds and configurations. Restore full snapshots with a single click if something breaks.

Multi-Instance Management

Host multiple Minecraft servers on different ports or switch active modpacks effortlessly from one centralized web dashboard.

Architecture

How Port Multiplexing Works

Traditional servers require separate ports for the game, web manifests, and admin consoles. Zircon does it on port 25565.

# 1. Start Zircon Server Manager ./zircon-server --port 25565 --admin-port 25564 # Public Address: 25565 (serves Minecraft protocol + REST mod manifests) # Local Admin Panel: http://localhost:25564 (secure dashboard with generated password)
Security by design: The admin dashboard (25564) stays local or behind your VPN/reverse proxy. Only the multiplexed Minecraft port (25565) needs to be forwarded to your players.
