Signal Lens

A Visual Debugger for Signals
Supports Godot 4.3 and 4.4.

Features

• Click on a node in the remote scene tree and instantly view all its signals' connections.
• View signal emissions in real-time as they are emitted in-game.
• Select and rearrange a graph view to inspect your signal connections.
• Keep signal emissions so you can inspect them later.
• Modify the signal emission speed so you can fine-tune the experience for your debugging purposes.
• Supports inspection of built-in and custom signals.
• Supports inspection of built-in, custom and autoload nodes — if it's in the remote tree, you can inspect it.
• Draws both anonymous and named callables that are connected to a signal.
• Inspection of Object, RefCounted and Resource types not supported (yet!)
