ModGUI

ModGUI is a free, self-hosted moderation plugin for Paper servers, with graphical tools for punishing, investigating, and reporting players. Administrators can configure punishment types, icons, permissions, console commands, and durations; actions run as console commands and can work with LiteBans, AdvancedBan, EssentialsX, and other punishment plugins. Its investigation interface can show a player's current-session anticheat flags through GrimAC, which is optional and needed for that tracking. Staff can add notes to a player, and players can file reports using /report with optional severity levels. Discord webhooks can relay punishments, anticheat alerts, reports, and staff notes, with optional role pings. A recovery compass opens the investigation interface on right-click. ModGUI requires Paper 1.21.11 or newer. Installation involves adding the JAR to the server's plugins folder, restarting, configuring files, and running /modgui reload. Configuration covers punishment settings, GUI borders, messages, webhook URLs, GrimAC thresholds, ignored checks, and report cooldowns. The plugin is released under the MIT License.

ModGUI brings punishment, investigation, reporting, and Discord logging into a Paper server plugin. Check the Paper version requirement before installing; GrimAC is needed only for anticheat flag tracking.

ModGUI suits administrators of Paper servers who want configurable moderation tools and Discord logging. GrimAC is relevant only for servers that want anticheat flag tracking.

ModGUI is a self-hosted Paper plugin for server teams that want a shared interface for staff actions and player reports. It works alongside command-based punishment plugins rather than replacing them, but its anticheat investigation tools depend on GrimAC.

Its appeal is a configurable staff workflow with Discord logging at no software cost. The Paper version floor is a firm compatibility check, and the plugin’s usefulness depends on administrators setting up its permissions and configuration to match their process.

Overview

ModGUI combines punishment, investigation, staff notes, and player reporting in one server plugin. Punishments are dispatched as console commands, so teams can connect the GUI to LiteBans, AdvancedBan, EssentialsX, or another punishment plugin while keeping their existing backend. That makes it a staff-facing layer, not a substitute for a punishment system.

Installation means placing the JAR in the plugins folder, restarting the server, configuring the files, and running /modgui reload. Administrators can set punishment types and durations, GUI borders, messages, webhook URLs, GrimAC thresholds, ignored checks, and report cooldowns. The breadth is useful for tailoring a workflow, but it also puts the burden on staff to configure it deliberately.

Key features

Staff actions and investigation

The punishment GUI supports configurable types, icons, permissions, commands, and durations. This suits teams that need different actions or access by staff role; compatibility depends on configuring the console commands for the punishment plugin in use. The investigation GUI shows a player's anticheat flags for the current session through GrimAC. GrimAC is optional for ModGUI overall, but required for this specific view, so teams without it should not expect anticheat flag tracking.

Staff can attach notes to a player, and a recovery compass opens the investigation GUI on right-click. That gives staff a quick route into investigation and record-keeping tools, while the README-documented permissions cover administration, punishment types, investigation, notes, spyglass use, reporting, and player exemptions.

Reports and Discord logging

Players submit reports with /report, with optional severity levels. Discord webhooks can send punishments, anticheat alerts, reports, and staff notes to a staff channel, with optional role pings. These integrations bring several moderation events together, though they rely on configuring webhook URLs and, for anticheat alerts, GrimAC.

Pricing

ModGUI is free: its plan costs free. The MIT License permits use, copying, modification, distribution, sublicensing, and sale without charge, and provides no warranty. There are no paid tiers or seat and quota limits given; the practical requirement is a compatible Paper server.

Platforms

ModGUI is self-hosted and requires Paper 1.21.11 or newer. Modrinth identifies compatibility with Minecraft Java Edition 1.21.11 on Paper. GrimAC is an optional integration, but required to track anticheat flags. Teams on other server platforms or older Paper versions should look elsewhere.

Who it's for

ModGUI is a fit for Paper server teams that want a configurable punishment interface layered over an existing command-based system, along with reports, staff notes, and Discord event logging. It is less suitable for teams that need a standalone punishment backend, anticheat flag tracking without GrimAC, or compatibility with an older Paper release.

Pros and cons

• Pros: Punishments run as console commands, allowing integration with several established punishment plugins rather than forcing a replacement.
• Pros: Reports, notes, punishments, and anticheat alerts can feed into Discord webhooks, with optional role pings.
• Pros: The configurable GUI and documented permissions give administrators control over actions and staff access.
• Cons: Paper 1.21.11 or newer is required, excluding older Paper servers.
• Cons: The investigation GUI's anticheat flags require GrimAC, so that feature is not available on its own.
• Cons: The first release is v1.0.0, and the project's public GitHub page currently shows zero issues; teams seeking an established support discussion should weigh that before adopting it.

Alternatives

Choose LibertyBans if you want a free punishment plugin with API and self-hosted platforms, Java 17 support, and supported Minecraft server platforms. Staff+ is another free self-hosted option if Paper, Purpur, or Folia 1.20–1.21+ and Velocity 3.3.0+ support matters more than ModGUI's particular workflow.

For a broader set of anticheat checks alongside reports, inspection tools, and Discord notifications, consider Nimbus AntiCheat, which includes 43 checks, Paper 1.21.8 support, and per-check punishments. ExtraBan is another free self-hosted plugin. Player Report is a free self-hosted report plugin, while ReportsGUI is free and supports up to 54 unhandled reports.

Pick BanManager if you want a free open-source option spanning API, Linux, self-hosted, and web platforms. AdvancedSensitiveWords is a free self-hosted alternative. Browse Minecraft Moderation Plugins for more options.

Verdict

ModGUI is a strong fit for Paper 1.21.11+ teams that want configurable staff actions, player reports, notes, and Discord logging without replacing a command-based punishment plugin. Its central reason to choose it is that unified workflow; look elsewhere if you need an older Paper version, a standalone punishment backend, or anticheat flag tracking without GrimAC.
