Redstone Debugger v1.0.0 — the real thing, not a mockup

No demo video — run it yourself

We do not publish mockups as proof of working software. This page describes build 1.0.0: launch it, follow the tutorial step by step, or read the docs — every claim links to something you can execute today. Recorded walkthroughs are tracked on the roadmap.

Why it exists

Purpose

Redstone is the most complex thing you can build in Minecraft, yet debugging it means staring at torches. Redstone Debugger records circuit activity, replays it, and analyzes it — turning redstone engineering into something you can inspect, not guess.

Who it's for

Technical builders, map makers, redstone engineers, educators teaching redstone logic, and automation designers.

Key capabilities

Circuit recorder

Records redstone events into a timeline with atomic tick ranges.

Diagnostic engine

A heuristic analyzer that identifies signal paths, problems, and scoring.

Replay & analysis

Step through recorded timelines to understand exactly what happened.

AI-assisted insights

Optional AI providers (including local Ollama) help explain circuit behaviour.

Features

Redstone Debugger — feature registry

12 features across 4 categories — all real, all working.

Recording 3 features

Circuit Recorder

Records redstone events into a timeline with atomic tick ranges.

25 Event Types

Wire, lever, repeater, comparator, observer, torch, button, piston, pressure plate and more.

Auto-Stop

Recording auto-stops at extreme event counts to protect performance.

Analysis 4 features

Diagnostic Engine

Heuristic analyzer that identifies signal paths, problems, and scoring.

12 Analysis Algorithms

Signal tracing, dependency chains, root cause, SCC cycles, critical path, clock detection.

Timeline Replay

Step through recorded timelines to understand exactly what happened.

AI-Assisted Insights

Optional AI providers (including local Ollama) explain circuit behaviour.

Visualization 3 features

World Overlays

Visual overlays showing signal states directly in the world.

HUD Overlays

In-game HUD showing recording status and diagnostics.

Export

Export recordings for later analysis or sharing.

Commands 2 features

/rdebug Suite

Recorder, timeline, clear, export and perf commands.

Performance Manager

Profiler, metrics, caching and memory monitoring.

Quick start

Get started with Redstone Debugger in minutes

Follow these steps — most installs take under five minutes.

Step 1

Install Fabric and drop the Redstone Debugger JAR for your Minecraft version into your mods folder — best-tested on 1.21.11.

Step 2

Launch the game and open a single-player world; stand near the circuit you want to understand.

Step 3

Run /rd help to explore the command suite: recorder, timeline, clear, export and perf.

Step 4

Press R near the circuit to start recording, then R again to stop — events land in a timeline with atomic tick ranges.

Step 5

Open the timeline and step through recorded events one tick at a time; world overlays highlight the corresponding blocks.

Step 6

Run diagnostics to surface problems in the recorded activity — /rd explain or /rdebug diagnose <n>.

Step 7

Optionally configure an AI provider (including local Ollama) for AI-assisted insights — all core diagnostics work without one.

Step 8

Export a recording to share it — the recipient can replay and re-diagnose without your world.

FAQ

Questions, answered

Does it slow the game down?

The recorder is lightweight and auto-stops at extreme event counts, backed by a performance manager with profiler, metrics, caching and a memory monitor.

Do I need an AI provider?

No — all core diagnostics work fully offline. AI insights are an optional add-on, including local Ollama.

Is it server-side or client-side?

It operates client-side; recording is single-player oriented.

What can it record?

25 event types via mixins — wire, lever, repeater, comparator, observer, torch, button, piston, pressure plate and more — captured into a timeline with atomic tick ranges.

Is there a command interface?

Yes — /rdebug covers recorder, timeline, clear, export and perf, plus world and HUD overlays. /rd explain and /rdebug diagnose <n> run the diagnostics.

Can it explain my circuit?

Yes — the AnalysisEngine runs 12 algorithms (signal tracing, dependency chains, root cause, SCC cycles, critical path, clock detection) and can call an optional AI provider (including local Ollama).

Which Minecraft version should I use?

Best-tested on 1.21.11 — some advertised versions lack version-specific compat code, so verify before relying on them. 26.x builds are newer with bundled mappings; keep the build matched to your Minecraft version.

Can I share a recording?

Yes — export a recording from the command suite. The recipient can replay and re-diagnose the event timeline without your world.
