Console Filter Next

An improved fork of ConsoleFilter for Minecraft Forge, Fabric, and NeoForge. Filter console output by text, regex, log level, thread, logger/source, and mod id — not just plain text. Reduce noise on the client or dedicated server while debugging modpacks and development environments.

Loaders: Forge · Fabric · NeoForge (separate JAR per loader)
Discord: discord.gg/CcUNTJjPD · Issues: GitHub · Releases: GitHub Releases

Install on either or both sides (optional on client and server): use it only where you read logs.

Features

• Filter types: basic text, regex, log level, thread, logger/source, mod id
• Profiles: default, debug, production — switch in-game, via TOML, or /consolefilter profile (persisted)
• Modes: blacklist (hide matches) or whitelist (show only matches); optional ignoreCase
• In-game editor (Forge/NeoForge Mods → Config; Fabric Mod Menu): paginated lists, regex validation, presets, import/export
• Commands (OP 2): reload, list, status, export, import, profile
• filterLatestLog — apply filters to latest.log and other Log4j file appenders
• skipMessagesWithStackTrace — never hide lines with exceptions or stack traces
• Statistics: per-filter-type hit counts in /consolefilter status
• Hot reload from file, commands, or Save & Apply in the config UI

Configuration

In-game

1. Go to Options → Mods
2. Find Console Filter Next
3. Click Config
4. Edit filters and options; Save & Apply writes consolefilternext-common.toml and reloads filters

Config file

Edit config/consolefilternext-common.toml in your instance folder.

Example — filter INFO messages from the Server thread:

[general]
activeProfile = "default"
ignoreCase = false
whitelistMode = false
filterLatestLog = true
skipMessagesWithStackTrace = false

basicFilters = [] levelFilters = ["INFO"] threadFilters = ["Server thread"] sourceFilters = [] modIdFilters = [] regexFilters = []

More examples (whitelist mode, mod id filters, profiles, regex): README.

## Tips

**Filter all DEBUG messages**

```toml
levelFilters = ["DEBUG"]

Filter messages from a specific package

sourceFilters = ["com.example.mymod"]

Whitelist mode — show only matching messages

whitelistMode = true
basicFilters = ["ERROR", "WARN"]

If any filter matches, the message is filtered out (unless whitelist mode is enabled).
