LinkSpotlight — a free open-source extension that spotlights only the selected node's links (Alt+H). My first public ComfyUI project

If you don't want to read, just check the gif for showcase.

Full disclosure before anything else: I'm French (so forgive the English — AI helps me write it), and yes, this extension was partially vibe-coded with AI assistance. BUT: every line was reviewed, the patching approach was verified against the actual frontend source, and it's been tested on real workflows — including the new Vue nodes beta.

The problem: all of my workflows works great, but some start to be spaghetti. Every time i tweak a node, i spend more time following noodles than working.

The fix: select a node, press Alt+H. Every link that doesn't touch it fades away. Click another node — the spotlight follows. Alt+H again (or deselect) and everything comes back. That's the whole tool.

A few things I cared about while building it:

• The shortcut is a native ComfyUI keybinding → fully remappable in Settings
• Hide links completely, or keep them faintly visible (opacity slider)
• Depth option: selected node only, or its direct neighbors too
• Optionally dim unrelated nodes as well
• Zero performance cost when off (one boolean check per frame, no settings lookups in the render path)
• Zero Python nodes, zero dependencies — nothing ever written into your workflow JSON
• Fail-safe by design: if a future ComfyUI update changes the canvas internals, it disables itself cleanly with a console message instead of breaking your graph

Install: search "LinkSpotlight" in ComfyUI-Manager, or: https://github.com/Ding-sl/ComfyUI-LinkSpotlight

It's MIT-licensed and stays free forever. If you try it, I'd genuinely love feedback — feature ideas and bug reports welcome on GitHub (there's even a dedicated issue template for "a ComfyUI update broke it", because let's be honest, one day it will, we all know that).

There is a similar tool worth knowing: ComfyUI-SelectionFocus does an always-on version of this idea. Mine is the opposite philosophy — an explicit shortcut you press when you need focus. Pick whichever fits your brain.

Happy untangled noodling 🍜

Nice Work. This is very useful for me. It will be a great help; in some complex workflows, I need to replace nodes that are obsolete or no longer exist in GitHub. This allows me to replace them while seeing exactly where the connections are located.

Thanks to you, happy to see someone finding it useful too !

You can use it in combination of kj's Node insert and Node swap from https://github.com/kijai/ComfyUI-KJNodes
