I used to wonder what secret buttons the developers had access to until Debug Utils Mod unlocked that reality. For a developer like me who builds modded worlds and experiments with mechanics, being able to visualize entity paths, structure bounds, and point-of-interest (POI) updates in real time feels like seeing the game’s inner workings laid out in neon.

What You Really Can Do with It
According to Modrinth, Debug Utils restores features removed from the public release tools designed initially for Mojang devs for both Fabric and Forge users. It works on both client and server, and the latest version (1.0.9) supports Minecraft 1.21.8 across Fabric, NeoForge, and Forge.
Here’s what you’ll get with /debug_utils <feature>
:
- POI Tracking – see when villagers add or remove POIs.
- Block Updates – watch blocks updating around you in real time.
- Structure Generation – visualize the bounding boxes of generated structures.
- Entity Pathing & AI Goals – follow mob movement paths, inspect their decision logic.
- Raid Detection – quickly find raid centers.
- Other tools – bee hive checks, light levels, heightmaps, chunk ticking info—and more, all togglable.

What Devs and Creators Say
On Minecraft developer forums and subreddits, users praised these tools for making debugging interactive and visual:
“I can instantly verify where structure generation fails or which entity is blocking spawning.”
Platforms like these are golden, especially when you’re diagnosing weird chunk or AI behaviors live.
Whether I’m troubleshooting entity overlap in redstone contraptions or fine-tuning biome generation for a map, the modular debug switches make adjustments feel intuitive.
Why It Has Become Essential for Me
After using this mod and trusting its suite of tools I now build more confidently. Seeing a mountain of data (such as entity brain states or chunk load info) laid bare right in-game saved me hours of guesswork. Plus, toggling these features off cleans up the screen again. It’s like switching between ‘developer goggles’ and a normal view with a flick.
