Mojang Dev Tools

Unlocks all hidden developer features normally only available inside Mojang's IDE — with an in-game config menu to toggle each flag individually. ALL TOOLS EXIST IN OFFICIALLY RELEASED MOJANG BINARIES, THIS MOD SIMPLY ENABLES THE FLAGS

Sets SharedConstants.IS_RUNNING_IN_IDE = true and MC_DEBUG_HOTKEYS=true at class-load time, enabling debug overlays, internal commands, and dev-mode keybinds that are shipped in the game but never exposed in production.

Requirements

• Minecraft 26.1.2
• Fabric Loader 0.19.2 or later

Key Features

Debug Keybinds (F3 held)

Note: F3+F with this mod enabled toggles fog instead of cycling render distance — this is the dev-mode override.

Renderer Overlays

Toggle any of these in-game via F3 + F6:

• Pathfinding route overlay
• Block neighbor update overlay
• Structure bounding box overlay
• Mob brain & memory overlay
• AI goal selector overlay
• Point of interest (POI) overlay
• Bee hive/path overlay
• Raid state overlay
• Village section overlay
• Entity hitbox overlay (integrated server)
• Block collision shape overlay
• Sculk catalyst spread overlay
• Breeze mob debug overlay
• Experimental redstone wire update order overlay

World Generation Debug

• Cave carver volume overlay
• Ore vein bounds and type overlay
• Aquifer cell boundary overlay
• Per-chunk feature placement count heatmap
• Large dripstone cluster overlay
• Disable individual world gen passes (fluids, aquifers, surface, carvers, structures, features, ore veins, blending, retrogeneration)

Gameplay & QOL Flags

• All villager trade tiers unlocked immediately
• Ignore mob cap on integrated server
• Open worlds from incompatible versions
• Allow simulation distance below the normal minimum
• Keep jigsaw blocks after structure generation
• Structure edit mode
• Save structures as SNBT text files
• Per-tick timing monitor
• Show all sound subtitles
• Suppress outbound Mojang telemetry
• Cursor position in F3 overlay
