ChatSentinel vs LibertyBans

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.

LibertyBans is a free Minecraft punishment administration plugin designed for large networks as well as single servers with limited resources. It handles bans, mutes, warnings, kicks, temporary punishments, and removal commands for players and IP addresses. Configurable templates can set punishment type, reason, and duration, while exemptions restrict which staff members may punish others. The plugin can identify suspected alternate accounts, apply IP bans to them, show suspected accounts with a command, and notify staff when they join. It supports Bukkit, Spigot, Paper, Purpur, Folia, BungeeCord, Waterfall, Fabric, Sponge, and Velocity. Storage options include local HyperSQL or remote MariaDB, MySQL, and PostgreSQL databases; multiple proxies and server instances can be synchronized. LibertyBans also provides a developer API for other plugins. It requires Java 17, and Fabric installations also require adventure-platform-mod. For mutes on a Velocity proxy, SignedVelocity must be installed on both proxy and backend servers. The project says its dependencies use secure SHA-512 hashes and that builds are reproducible so checksums can be verified.
