About this Mod
SwearFilter
A lightweight, client-side chat filter that censors inappropriate words in incoming messages — no server installation needed.
Features
- Automatically censors filtered words in chat, replacing them with
#of the same length (e.g.damn→####) - Whole-word, case-insensitive matching —
helloandclassare left alone - Covers both player chat and system/server messages
- Fully configurable in-game through Mod Menu (powered by Cloth Config):
- Toggle filtering on/off
- Add or remove words from the list
- Reset to the default list
- Settings save to
config/swearfilter.json
Requirements
- Minecraft 26.1.2 (Fabric)
- Fabric API
- Cloth Config
- Mod Menu (optional — needed to open the settings screen)
Notes
- Client-side only: safe to use on any server, and not required by other players.
- Censoring replaces the text only; line color/formatting on a censored message isn't preserved.

SwearFilter 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 (26.1.2). You can switch loaders with one click in the panel.
Is SwearFilter compatible with fabric?
SwearFilter officially supports fabric for Minecraft 26.1.2. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with SwearFilter – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if SwearFilter 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.
