SignalMap — Godot 4 Signal Dependency Visualizer

SignalMap scans your entire Godot project — both .gd scripts and .tscn scene files — and maps every signal definition, emission, and connection. Generates an interactive HTML graph where hovering a node highlights only its signal connections. Finds orphan signals nobody listens to and dead handlers connected to functions that don't exist.

Single Python file. Zero dependencies. 100% local.

Scans .gd scripts AND .tscn scene connections

Interactive SVG graph with hover highlighting
