Expose any server port to the internet via ngrok and cloudflared tunnels — no extra port allocations needed.
Expose any local port to the internet via ngrok or cloudflared — no port allocations needed. Includes a full browser-based management dashboard.
TunnelMC is a Bukkit/Spigot/Paper plugin that automatically downloads and manages ngrok and/or cloudflared, creates tunnels for any local port, and broadcasts the public URL to console and online OPs the moment the tunnel is ready.

🌐 Two Tunnel Providers — ngrok and cloudflared, configurable per tunnel. Mix them freely.
🔑 Multiple ngrok Accounts — Each ngrok tunnel has its own authtoken (required for v3). Run different accounts simultaneously.
🚀 Zero-Setup Quick Tunnels — Cloudflared quick tunnels work out of the box with no account.
📌 Custom Domains — Cloudflared named tunnels give you persistent custom hostnames via Cloudflare Zero Trust.
🖥️ Web Dashboard — Full management UI. Create/edit/delete tunnels live, download binaries, change settings — all from a browser.
⚡ Auto-Download — Detects OS and CPU arch, downloads the right binary on first use. Cached forever after.
🔔 Instant URL Broadcast — URL goes to console and all online OPs the moment the tunnel is ready.
🎮 Full Command Support — /tunnel with tab completion for everything.
🔁 Auto-Restart & Crash Loop Protection — Tunnels restart after failure. Stops retrying if it fails too many times in a short window.
🩺 Health Checks — ngrok tunnels get API-level checks; cloudflared tunnels get process-alive checks.
🐋 Pterodactyl Compatible — Tunnels are outbound connections, so no extra port allocations are ever needed.

ngrok free: one active tunnel at a time, random URL on each restart, bandwidth limits. Authtoken is required for all ngrok v3 tunnels. Per-tunnel authtokens let you use multiple free accounts to work around the one-tunnel limit.
Cloudflared quick tunnels: HTTP only, random *.trycloudflare.com URL, no bandwidth limits.
Cloudflared named tunnels: require a Cloudflare account (free), any protocol, persistent custom domain.
No extra port allocations needed — tunnels are outbound connections only. The dashboard also binds locally and doesn't need an allocated port.
Slow download? TunnelMC will warn after 30 seconds with manual install steps. Place the binary at plugins/TunnelMC/ngrok/ngrok or plugins/TunnelMC/cloudflared/cloudflared and restart.

NodeRunner — Run a Node.js Discord bot inside your Minecraft server.
PyRunner — Run a Python Discord bot inside your Minecraft server.
TunnelMC pairs perfectly with both — a cloudflared quick tunnel to port 8080 makes their dashboards publicly accessible with zero port allocation.
