Recommended Server-Side Mods

This guide covers essential server-side mods that can help improve your Minecraft server's performance, stability, and moderation capabilities. These mods are particularly useful for running modded servers like Homestead.

Performance & Optimization

ServerCore

A comprehensive optimization mod that reduces lag and improves TPS through various configurable features.

PurposeStable TPS and server-sided stabilization
PlatformFabric, Forge, NeoForge
DownloadModrinth

Key Features:

  • Optimizations for chunk ticking, mob spawning, and player logins
  • Configurable entity processing limits to reduce lag spikes
  • Dynamic view distance adjustment based on server load
  • Mob breeding caps to prevent animal spam
  • Async player login handling

Useful Commands:

  • /servercore status - View current dynamic settings
  • /servercore reload - Reload configuration
  • /mobcaps - Display current per-player mobcaps

Alternate Current

An efficient redstone implementation that dramatically reduces lag from redstone dust.

PurposeEfficient redstone contraptions
PlatformFabric, Forge, NeoForge
DownloadModrinth

Key Features:

  • Up to 30x lower MSPT (milliseconds per tick) from redstone dust
  • Up to 20x fewer block updates from redstone networks
  • Predictable and intuitive update order (no more location-dependent behavior)
  • Drop-in replacement with minimal code modifications

TT20 (TPS Fixer)

Reduces the feeling of lag by recalculating tick times based on current TPS.

PurposeReducing lag feel when TPS is low
PlatformFabric
DownloadModrinth

How It Works:

TT20 uses the formula ticks * tps / 20 to recalculate how long actions take. For example, when breaking a block at low TPS, it adjusts the break time so players don't notice the lag as much. The end user feels almost no lag even when TPS drops.

Note: TT20 fixes the symptoms of TPS lag, not the underlying cause. Use it alongside other optimization mods for best results.


Connection & Stability

Raknetify

Improves multiplayer experience for players with unstable or rate-limited connections.

PurposeFixing disconnection and ping issues
PlatformFabric, BungeeCord, Velocity
DownloadModrinth

Key Features:

  • Uses RakNet protocol for higher reliability and lower latency
  • Multiple channels with priorities for better packet handling
  • High MTU mode for reduced overhead and improved throughput
  • Streaming compression to reduce bandwidth usage

Requirements:

  • Requires installation on both client and server
  • Needs a UDP port opened at the same port as your server
  • Players connect using the raknet; prefix (e.g., raknet;play.yourserver.com)

Too Fast

Removes the annoying "moved too quickly" warning and rubber-banding effect.

PurposeEliminates speed-related rubber-banding
PlatformFabric, Forge
DownloadModrinth

Key Features:

  • Removes server-side limitations on player speed
  • Eliminates "player XYZ moved too fast" console messages
  • Server-side only - no client installation needed

Warning: Do not use alongside Random Patches as they conflict.


Neruina - Ticking Entity Fixer

Prevents ticking-related crashes from corrupting your world.

PurposeFixing ticking entity crashes
PlatformFabric, Forge, NeoForge
DownloadModrinth

Key Features:

  • Suspends problematic entities instead of crashing the server
  • Entities can still be interacted with but won't cause crashes
  • Block inventories remain accessible even when block entities are suspended
  • Kicks players instead of crashing if a player causes tick errors
  • Tracked issues persist across server restarts

Useful Commands:

  • Copy crash info to clipboard
  • Teleport to problematic entity
  • Attempt to resume ticking
  • Kill/remove the problematic entity
  • Auto-generate GitHub issue reports (1.19+)

Moderation & Anti-Grief

Ledger

A comprehensive logging and rollback system for Fabric servers.

PurposeRollbacks and anti-grief
PlatformFabric
DownloadModrinth

Key Features:

  • Tracks hundreds of in-game events (block placement, item transfers, entity kills, etc.)
  • Easy inspection and rollback for moderators
  • MySQL and H2 database support
  • Fast lookup with database indexing

Action Types Tracked:

  • Block breaks and placements (by players, mobs, or other causes)
  • Item insertions, drops, and pickups
  • Entity kills
  • And many more...

Key Commands:

  • /ledger search - Search through logged actions
  • /ledger rollback - Rollback griefed areas
  • /ledger restore - Undo rollbacks
  • /ledger purge - Delete old log entries

Diagnostics & Debugging

Observable

A profiling mod that shows you exactly what's causing lag on your server.

PurposeFinding what's lagging your server
PlatformFabric, Forge
DownloadModrinth

Important: Observable requires installation on both the server AND client to use.

Key Features:

  • Profiles entities and block entities to show tick time usage
  • In-game GUI with organized performance data
  • 3D overlay that highlights laggy blocks and mobs
  • Copyable teleport commands to jump to lag sources
  • Web-based results list for detailed analysis

How to Use:

  1. Press R (default keybind) to open the profiler GUI
  2. Set the profile duration (default 30 seconds)
  3. Click "Profile TPS" to start
  4. Review results to identify lag sources

Tip: Use Observable alongside Spark for comprehensive performance analysis. Observable finds specific lag sources, while Spark provides overall server metrics.

Requirements:

  • Requires operator permissions to use
  • Needs Kotlin library mod (Kotlin for Forge or Fabric Language Kotlin)

Immersion & Gameplay

Voice Chat Interaction

Makes Simple Voice Chat interact with the Minecraft world through sculk sensors and wardens.

PurposeSkulk sensor and warden voice detection
PlatformFabric, Quilt (Server-side)
DownloadModrinth

Note: Simple Voice Chat is already included in Homestead!

Key Features:

  • Talking in voice chat activates nearby sculk sensors
  • The warden can detect players talking in voice chat
  • Sneaking while talking doesn't trigger vibrations (configurable)
  • Configurable volume threshold
  • Optional support for whisper and group chat vibrations

Configuration Options:

  • group_interaction - Trigger vibrations in group chats
  • whisper_interaction - Trigger vibrations when whispering
  • sneak_interaction - Trigger vibrations while sneaking
  • voice_sculk_frequency - Custom vibration frequency (default: 7)
