ConsoleFilterNext

Console Filter Next

An improved ConsoleFilter mod for Forge, Fabric, and NeoForge that filters log messages by text, regex, log level, thread, source, and mod id. Reduce console noise and focus on what matters — ideal for debugging modpacks and dedicated servers.

Works on the client and dedicated server (optional on each side). Download the JAR for your loader (*-forge, *-fabric, or *-neoforge). Do not mix loaders. Each file is Minecraft + loader; tags are {mc}-4.2.0.

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

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).

Compatibility

Not every loader exists on every Minecraft version. Pick the file that matches your game + loader. Tags are {mc}-4.2.0.
