Display Everything

Display Everything is a debug node: plug anything into it, run the graph, and it shows you what's actually flowing down that wire. No type restrictions, no conversion step - you drop it on any connection you're unsure about and it tells you what's there.

Why you'd reach for it

Every ComfyUI user eventually hits the same wall: a value looks wrong three nodes downstream and you have no idea where it went sideways. Did the LoRA loader actually pick up your strength value? Is that string node emitting what you think it's emitting? The normal fix is dropping a Preview Image or a Show Text node, but those are type-specific - you need a different node depending on what you're inspecting. Display Everything is the type-agnostic version: one node, works on anything, wherever your graph goes wrong. It plays the same role rgthree-comfy's Display Any does in that pack, for people who already lean on that kind of "just show me the value" node when debugging.

How it works

It's an output node, meaning it can sit at the dead end of a wire the way Preview Image or Save Image does - you don't need to route anything out of it for it to do its job. Feed it a value, run the queue, and it renders whatever landed there back onto the node.

Inputs and outputs

There's one input, source, typed as a wildcard so anything can plug into it - an image, a string, a number, a whole conditioning object. The output slot mirrors that as a wildcard too, so if you do need to keep the value flowing rather than dead-ending the wire, you can chain something after it. On simple values (strings, ints, floats) the display is genuinely readable at a glance; on something dense like a full CONDITIONING or MODEL object, expect a much less friendly dump - it's built for spot-checking, not for browsing a data structure comfortably.

Installing it

Ships with ComfyUI SKBundle, u/skbphy's personal node pack - built with help from Cursor AI, by their own account, and inspired by rgthree and mxToolkit. Through ComfyUI Manager, search ComfyUI SKBundle. By hand:

cd ComfyUI/custom_nodes
git clone https://github.com/SKBv0/ComfyUI_SKBundle.git
pip install -r requirements.txt

Restart ComfyUI. Pure debug plumbing - no models, no heavy dependencies beyond whatever's in the pack's requirements.txt.

Common issues

The main friction is just knowing it exists - a lot of people debug with a chain of Preview Image / Show Text nodes because that's what ComfyUI ships by default, and don't realize a single universal display node saves the type-matching hassle. Once you're using it, the only real gotcha is on big objects: if the node renders a wall of text you can't parse, that's not a bug, it's just not the right tool for that particular value - swap in a type-specific viewer (Preview Image for images, a proper JSON viewer for anything structured) once you've narrowed down where the problem is. Use Display Everything to find which wire is wrong, then reach for something more specialized to see why.
