ChatSentinel vs SModeration

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.
