Wardline | Crash & Lag Protection v1.0.0

Wardline
Wardline stops the crash commands, redstone clocks, TNT cannons, and mob-stacking builds that bring a server down. It watches every chunk against per-world limits and either flags what it sees or blocks it outright, all from one config.

Built for: Survival and SMP servers, or any owner who wants a safety net against griefers and lag machines without babysitting the console.



5 wards

• Entity limit caps monsters, animals, dropped items, projectiles, and misc entities per chunk, so mob-stacking and item-drop farms stop before they lag the server.
• Falling block limit caps active falling blocks (sand, gravel) per chunk, stopping falling-block generators from flooding a chunk.
• Redstone limit caps redstone updates per chunk in a rolling window, so redstone clocks and lag machines get held flat instead of tanking the tick rate.
• Explosion limit trims how many blocks one explosion can break and caps primed TNT per chunk, stopping giant TNT cannons from wrecking terrain or the server.
• Command guard refuses known crash commands, absurdly long commands (selector bombs), and command spam faster than a person can type.

Every ward can enforce (block it) or just log it, per world.

Per-world profiles

Every world runs a named profile that turns wards on or off and sets their limits. Any world you do not list runs the default profile, and any setting a profile leaves out falls back to the default too, so you only write the differences for a special world. Ship a relaxed profile for a creative or build world and keep survival locked down, all in the same config.

Control panel and incident log

/wardline panel opens a menu listing every loaded world, its profile, and how many wards are active, and clicking a world shows each ward's state and limits. /wardline log opens a paged menu of recent incidents, newest first, showing what was stopped or flagged, in which world, and why. Both menus are read-only, so a click can never race your config file.

Safe mode
Turn on safe mode to trial Wardline on a live server: every ward still watches and records what it would have stopped, but blocks nothing. Watch the log for a few days, confirm it is not catching normal play, then turn enforcement on.

Discord alerts
Paste a Discord webhook URL and Wardline posts one message per incident to your channel. It contacts nothing except that URL and never sends email. Choose whether to alert on everything or only on incidents it actually blocked.

Commands

• /wardline panel opens the per-world control panel. Aliases: /wl, /wards.
• /wardline log opens the incident log menu.
• /wardline list [page] prints recent incidents to chat.

• /wardline world <name> shows ward status and limits for one world.
• /wardline wards lists every ward and what it protects against.
• /wardline clear clears the incident log.
• /wardline reload reloads config.yml and messages.yml.
• /wardline help shows the command list in game.

Every command has full tab completion.

Permissions

• wardline.use opens the control panel and incident log and views ward status. Default: operators.
• wardline.admin clears the incident log and reloads the config. Default: operators.

Configuration
config.yml is fully commented and covers safe mode, the scan window length, Discord webhook settings, incident log size and file logging, GUI sounds, and every profile's ward limits. All player-facing text lives in messages.yml with full MiniMessage support. Run /wardline reload to apply changes without a restart, and an update never wipes settings you already made, it only adds new keys.

Requirements

• Minecraft 1.21 to 26.1.2.
• Paper, Spigot, or Bukkit.
• Java 21.
• No other plugins required.

Installation

1. Put Wardline-1.0.0.jar in your plugins folder.
2. Start the server once to create config.yml and messages.yml.
3. Turn on safe mode first if you want to watch before it enforces, then edit the config and run /wardline reload.

Try it first
Wardline is live on our test server, hosted here on BuiltByBit. Use the test server link on this page to open the panel and the log before you buy.
