ChatLogic
Rule-based chat automation mod for Fabric. Create triggers that react to incoming chat or system messages and respond with configurable messages or commands using randomized delays.
About this Mod
ChatLogic
ChatLogic is a Fabric client-side utility mod for rule-based chat automation. It monitors incoming chat messages and automatically sends configured responses or commands when specific text appears.
When a message matches a rule’s trigger text, a response is scheduled and sent after a random delay within the rule’s defined range. If multiple responses are configured, one is selected randomly.
The mod is fully client-side, server-safe, and focused on precise, predictable behavior.
Configuration
ChatLogic is configured in-game using Mod Menu or via the config file located in .minecraft/config/chatlogic.json
Each rule consists of:
- Trigger text to match in chat
- One or more responses
- A minimum and maximum delay before responding
- Response type (chat message or command)
Rule syntax
match -> resp1|resp2|resp3 @min-max
Examples
apple -> orange @100-500
hello -> hi|yo|sup @200-800
joined the game -> welcome @500-500
If a response starts with /, it is sent as a command instead of a chat message.
Dependencies
- Fabric API
- Cloth Config
- Mod Menu (optional, for UI)
This is the first release, and I plan to add more features as I keep working on it.

ChatLogic server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.
Is ChatLogic compatible with fabric?
ChatLogic officially supports fabric for Minecraft 1.21.11, 1.21.10, 1.21.9. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with ChatLogic – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if ChatLogic consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
