I kept doing the same annoying thing in ComfyUI: wanting to try a different model's variations or a different model altogether, or a different resolution, and ending up either rewiring a tangle of noodles or keeping five slightly-different copies of the same workflow around just so I could run A/B tests on something. These two nodes exist so I could stop doing that. Pick from a dropdown, keep working.

Nodes

Hot Lazy Switch

Plug in up to 10 things of any type - models, images, conditioning, whatever

give each one a name, and pick which one feeds downstream from a single dropdown. The unpicked branches don't just get ignored, they don't run at all, so you're not paying the load/compute cost for every option every time, only the one you're actually using.

Sockets show up one at a time as you connect them, so the node isn't a wall of ten empty inputs on day one. Unplug something and its socket stays put rather than shuffling everything below it around.

Hot Resolution Mode Switch

For when you want the convenience of an aspect-ratio + megapixel resolution picker most of the time, but still want to drop in exact numbers sometimes. One dropdown flips the node between:

Resolution Selector - pick an aspect ratio and a target megapixel count, it does the math (same formula as ComfyUI's own built-in Resolution Selector node).
Manual Resolution - just type the width and height yourself.

Only the controls for whichever mode you're in are shown, so the node isn't cluttered with fields you're not using.

Installation

Clone into your ComfyUI custom_nodes folder and restart ComfyUI:

cd ComfyUI/custom_nodes
git clone https://github.com/Bloodwolfb/ComfyUI-HotSwitches.git

No extra Python dependencies required.

Requirements

Both nodes use ComfyUI's V3 node schema (comfy_api.latest.io), so they need a reasonably current ComfyUI build that ships that API.
