ChatSentinel vs ModGUI

ChatSentinel is a self-hosted moderation plugin for Minecraft Paper servers. Its local trie filter checks chat and can load word lists for 28 languages, with leet-speak normalization and abbreviation expansion. It can also moderate whispers, signs, books, and anvil renames. Flagged content can be blocked or masked, with configurable escalation to warnings, mutes, or staff alerts. Optional moderation API and LLM review layers can add checks; both are disabled by default, so the local filter can operate without API keys. The first layer uses an OpenAI-compatible moderation endpoint. The second accepts compatible chat-completions providers, including Ollama, LM Studio, vLLM, Azure OpenAI, Together, and Groq. SQLite is the default database, with MySQL and PostgreSQL also supported. An optional PlaceholderAPI integration exposes moderation-related player details as placeholders. The README lists Java 21 or later and a Paper server as requirements. It describes a fail-open pipeline: local filtering remains active if APIs are unreachable, with a configurable timeout before messages pass through. ChatSentinel is free and open source.

ModGUI is a self-hosted moderation plugin for Paper servers, with graphical tools for player punishments, investigations, and reports. Server staff can configure punishment types, icons, permissions, console commands, and durations; punishment actions can work with LiteBans, AdvancedBan, EssentialsX, and other punishment plugins. Its investigate screen can display a player’s current-session anticheat flags through optional GrimAC integration. Staff can attach notes to players, and players can submit reports with /report and optional severity levels. Discord webhooks can send punishment logs, anticheat alerts, reports, and staff notes, with optional role pings. A recovery compass opens the investigate GUI when right-clicked. Configuration covers GUI borders, messages, webhook URLs, GrimAC thresholds, ignored checks, and report cooldowns. ModGUI requires Paper 1.21.11 or newer; GrimAC is needed for anticheat flag tracking. Installation involves adding the JAR to the server’s plugins folder, restarting, configuring files, and running /modgui reload. It is free under the MIT License.
