The plugin manifest identifies version 0.0.2, author LearXD and API version 2.0.0; the README says APIs at version 2.0.0 or earlier are supported. The project is labeled vAlpha and uses the GPL-3.0 license. The GitHub releases page lists 0.0.2 as latest, dated October 1, with notes about fixing several fly bugs and an anti-auto-clicker issue. The README warns that unchecked feature options may still be in development or testing. It includes a demonstration section identified as a video from the maintainer’s channel. The listed feature set does not include replay analysis.

Nimbus AntiCheat is a free plugin for detecting cheats on Minecraft servers. Its movement prediction and packet inspection power 43 individually configurable checks across movement, combat, world, packet, and inventory categories. The checks account for conditions such as latency, server lag, movement buffs, teleports, knockback, flight toggles, and join grace. Detection and staff alerts are enabled by default; operators configure punishments before they are used. Available actions include configurable commands, kicks, temporary or permanent bans, freezes, setbacks, and cancellation of illegal actions. Staff tools include player reports, an inspection GUI, in-game check controls, violation logs, and commands for testing alerts and punishments. PacketEvents is required; PlaceholderAPI, Discord webhooks, Citizens, LiteBans, and a permissions plugin are optional integrations. Nimbus requires Java 21 and targets Paper 1.21.x; it was built and tested against Paper 1.21.8, while other 1.21.x builds are untested. It supports Java-edition players, not Bedrock or Geyser players.
