Epsilon Cloud

Off-server combat aim ML and artificial latency detection with zero impact on your server TPS.

What Epsilon Cloud adds

A clever combat cheat can stay inside vanilla reach and movement limits, making it invisible to purely physics-based rules. Epsilon Cloud fills that gap on our servers without using your CPU.

  • Combat aim analysis. Evaluates targeting and rotation behavior across fights using machine learning to catch kill aura and aimbots.
  • Artificial latency detection. Catches backtrack and fake lag cheats that abuse artificial latency without punishing high ping or lag spikes.
  • Off-server execution. Heavy machine learning and statistical checks run on Epsilon Cloud hardware rather than your Paper server CPU.
  • Live detection rollouts. New machine learning and behavioral checks deploy directly on Epsilon Cloud without plugin updates or server restarts.

Link a server

Every Paper server generates its own unique identity key file in plugins/epsilon/cloud.key on first boot. Never edit or share that file.

  1. Verify your account email

    Sign in on epsilon.ac and make sure your email address is verified.

  2. Run epsilon link in console

    Type epsilon link in your Paper server console (without the leading slash). Epsilon prints a one-time claim URL.

  3. Confirm in the dashboard

    Open the URL in your browser and name your server. It appears in your live dashboard immediately.

Server console command 
epsilon link

Grouping multiple proxy servers

Behind Velocity or BungeeCord, each Paper backend generates its own cloud.key. Never copy cloud.key between servers, because two machines using the same key overwrite each other.

  1. Link your first backend

    Create your server entry (for example, "NA Practice") by linking your Hub or first Paper server.

  2. Attach additional backends

    Run epsilon link on your next backend (Duels, KitPvP, FFA), open the link, choose Attach to an existing server, and pick "NA Practice".

All attached servers roll up into one shared server view, player roster, and concurrent player count automatically.

Offline safety and privacy

Streaming runs on its own background thread using around 3.5 KiB/s per player, so it never blocks gameplay packets. If the internet connection to Cloud ever drops, Epsilon holds up to 32 MiB in memory, drops silent mitigations safely, and keeps running every local check untouched.

Players chat, command arguments, sign text, and book edits never leave your server.
