Fiw Admin Utilities

by Fi3w0

Fiw Admin Utilities gives server staff one server-side toolset for moderation, performance, bans, reports and join messages, all under a single fiw command tree.

FabricForgeNeoForgeServer-side onlyAll rights reserved1.20.1 – 1.21.11

What it does

Staff can freeze and vanish players, run a lag watchdog, sweep entities, and set a maintenance mode that keeps players out with a custom message. Bans can be temporary or permanent, mutes and per-player history are kept, and an escalation ladder that server admins can edit sets the penalties applied over time. Item bans block specific items, with timed bans supported. Players submit reports, and staff are notified; AFK tagging and auto-kick are configurable.

The mod is server-side only, so players join with vanilla clients and nothing needs to be installed on their side. Files are published for Fabric, Forge and NeoForge, and the Forge line covers 1.20.1 while NeoForge uses the 1.21.11 build. On Fabric, the mod needs Fabric API and Fabric Language Kotlin. LuckPerms is supported, and without it the tools fall back to vanilla operator level 3. The mod is not open source and is released under All rights reserved, with public links to its source code and issue tracker.

Key features

  1. Vanish and freeze

    Staff can hide from other players, suppress their sounds, particles and mob targeting, and freeze a player with a reason that can auto-unfreeze.

  2. Dupe detection

    Heuristic detectors watch item signatures and rates. They only alert by default, and admins can add auto-freeze, kick or ban escalation.

  3. Player reports and AFK handling

    Players file reports that notify staff, and AFK players can be tagged or kicked automatically after a set time.

  4. Join messages and MOTDs

    Custom join and leave texts, rotating server greetings, broadcasts and first-join notices can be set per server.
