Two things you need first

Pedro Debug is a Meteor Client addon — it requires Meteor Client to load. OpSec Mod is mandatory to protect your account from DonutSMP's anti-cheat.

⚠

Install order matters

Install Fabric API and Meteor Client first, then OpSec Mod, then drop in Pedro Debug. Joining DonutSMP without OpSec Mod risks your account getting flagged.

Required base client

Meteor Client

The client Pedro Debug runs on top of.

Anti-ban — mandatory

OpSec Mod

Protects your account from DonutSMP's anti-cheat.

Modrinth
Required dependency

Fabric API

Needed by Meteor Client and Pedro Debug both.

⚠ Do not skip OpSec Mod — it's what keeps your account from getting flagged on DonutSMP.

MODULE 01 — DEEPSLATE BYPASS

See through the nether's deepslate layer

Pedro Debug renders the terrain DonutSMP normally hides behind its deepslate protection layer, so you can navigate restricted areas without triggering a flag.

MODULE 02 — SPAWNER NOTIFIER

Never walk past a spawner blind

A bright vertical beam marks every detected spawner, visible through walls and from a distance — know it's there before you see it.

MODULE 03 — ESP GRID OVERLAY

FAQ

Common questions

Is Pedro Debug detected on DonutSMP?
Pedro Debug is currently undetected when used alongside OpSec Mod. Modules are patched within 24 hours of DonutSMP server updates, but no client can guarantee permanent detection avoidance.
What does the deepslate bypass do?
It renders terrain normally obstructed by DonutSMP's deepslate protection layer, allowing navigation through restricted areas without triggering server-side flags.
Does Pedro Debug work with my launcher?
Yes. Pedro Debug runs on Fabric, which is supported by Modrinth App, Prism Launcher, Feather Launcher, Lunar Client, and most other major launchers.
Do I really need OpSec Mod?
Yes — it's mandatory. OpSec Mod protects your account from DonutSMP's anti-cheat. Running Pedro Debug without it puts your account at risk.
How does the spawner notifier work?
It scans the loaded world for mob spawners and marks each one with a vertical beam visible through terrain, updating in real time as you move.
