Deploy servers,
not complexity.

Everything you need.

From auto-scaling to API access — Nimbus handles the infrastructure.

Smart Auto-Scaling

Instances scale based on player count — configurable thresholds, idle timeouts, time-of-day schedules, and predictive warm-up.

Multi-Node Cluster

Distribute services across machines with automatic placement, failover, and mTLS cluster transport.

Zero-Config Proxy

Velocity auto-managed — forwarding, server list, MOTD, tab list and chat sync.

Auto-Download

Paper, Purpur, Leaf, Velocity, Forge, Fabric, NeoForge — fetched on demand.

Built-in Permissions

Groups, inheritance, tracks, audit log — no external plugin required.

REST API + WebSocket

Live events, bidirectional console, full programmatic control.

Bedrock Support

Geyser + Floodgate auto-configured — one network, all platforms.

Interactive Console

30+ commands with tab-completion, live logs and setup wizard.

From zero to running network.

Three steps. No panel, no database, no YAML graveyard.

  1. 1Install

    One curl command installs the controller. Java 21 is auto-provisioned.

  2. 2Configure

    Declare groups and dedicated services in TOML. Templates stack and compose.

  3. 3Scale

    Nimbus boots your proxy, spawns lobbies, and scales on player count live.
