A ComfyUI node pack focused on workflow organisation and flexibility. The centrepiece is a Bundle system for passing arbitrary named values through a single wire, alongside smart media loaders with built-in resize, a multi-LoRA loader, a full set of logic and switch nodes, image processing tools, latent utilities, and various quality-of-life helpers.

Installation

Clone the repository into your ComfyUI custom_nodes folder:

cd ComfyUI/custom_nodes
git clone https://github.com/Stibo/comfyui-nifty-nodes

Then restart ComfyUI. Optional dependencies for certain nodes:

pip install kornia        # reinhard_lab_gpu and perceptual_crossfade in Image Color Match
pip install color-matcher # additional color transfer methods in Image Color Match

Features

ComfyUI v3 native — built entirely on the comfy_api.latest API with proper define_schema, lazy evaluation, fingerprint_inputs caching and async execution where applicable
Bundle system — pass any number of named values through a single BUNDLE wire, with dot-notation support for nested structures
Smart media loaders — load images, videos or both with an integrated resize pipeline and optional frame rate control
Multi-LoRA loader — manage an entire LoRA stack in one node with per-row enable/disable and strength controls
Full logic suite — lazy and eager input switches, output routers, boolean operators, string/number comparisons and more
Image Color Match — 10 color transfer methods including GPU-accelerated options, batch multithreading and selective channel transfer
Search aliases on every node for fast discovery via the node search

Nodes

Bundle

The Bundle system lets you pack multiple values of any type into a single BUNDLE wire and unpack or access them wherever needed. This keeps graphs clean when many values need to travel together.

Bundle Pack

Packs up to 32 values of any type into a Bundle. An optional incoming Bundle can be merged — new values are added to it or overwrite existing keys.

Inputs

Name	Type	Required	Default	Description
bundle	BUNDLE	No	—	Existing bundle to merge into. New slot values overwrite keys with the same name.
value1 … value32	ANY	No	—	Values to pack. Controlled by `count`.
count	INT	No	1	Number of value slots to show (1–32).
hide_links	BOOL	No	False	Hide the connection wires going into this node to reduce visual clutter.

Outputs

Name	Type	Description
bundle	BUNDLE	The resulting bundle containing all packed values.

Bundle Unpack

Unpacks a Bundle back into up to 32 individual outputs. Output labels are set by renaming the slots, matching the keys used when packing.

Inputs

Name	Type	Required	Default	Description
bundle	BUNDLE	Yes	—	The bundle to unpack.
count	INT	No	1	Number of output slots to show (1–32).
hide_links	BOOL	No	False	Hide the connection wires going out of this node to reduce visual clutter.

Outputs

Name	Type	Description
bundle	BUNDLE	The original bundle, passed through unchanged.
value1 … value32	ANY	Unpacked values. Slots beyond `count` output `None`.

Bundle Get

Reads a single value from a Bundle by key.

Inputs

Name	Type	Required	Default	Description
bundle	BUNDLE	Yes	—	The bundle to read from.
key	STRING	Yes	`value1`	Key to read. Supports dot notation for nested keys, e.g. `settings.width`.

Outputs

Name	Type	Description
value	ANY	The value at the given key, or `None` if the key does not exist.

Bundle Set

Writes or overwrites a single key in a Bundle.

Inputs

Name	Type	Required	Default	Description
bundle	BUNDLE	Yes	—	The bundle to update.
key	STRING	Yes	`value1`	Key to write. Supports dot notation for nested keys, e.g. `settings.width`.
value	ANY	Yes	—	Value to store at the given key.

Outputs

Name	Type	Description
bundle	BUNDLE	Updated bundle. The original is not modified — a new copy is returned.

Slot Labels and Key Names

When you rename a slot in Bundle Pack or Bundle Unpack (double-click the slot label), the new name becomes the key used inside the bundle. The same label must be used on both ends for values to align correctly.

Dot Notation and Nesting

Keys use . as a path separator, allowing you to read and write into nested structures. For example:

Bundle Pack  →  slot label: "camera.fov"   →  value: 90
Bundle Get   →  key: "camera.fov"          →  returns: 90

You can nest arbitrarily deep: "render.output.format", "lora.0.strength", etc. Bundle Get and Bundle Set both support full dot-path access.

Merging Bundles

Bundle Pack accepts an optional incoming Bundle. Any values you pack are merged on top of it — existing keys are overwritten, other keys are preserved. This makes it easy to incrementally build up a shared parameter object across multiple nodes.

Media Loader

Load & Resize Media

The most versatile loader — accepts images and videos in a single node, with a built-in resize pipeline. A is_video boolean output lets you route the result differently depending on what was loaded.

Inputs

Name	Type	Required	Default	Description
file	COMBO	Yes	none	File to load. Supports image formats (jpg, png, webp, …), animated formats (gif, apng, webp, avif) and video formats (mp4, mkv, webm, …).
force_frame_rate	INT	No	0	Enforce a specific frame rate. 0 = keep original. Values like 24, 30 or 60 resample the video during loading.
resize	DYNAMIC	No	off	Resize mode to apply after loading — see Resize Modes.

Outputs

Name	Type	Description
IMAGE	IMAGE	Loaded frames as a batch tensor. `None` if file is `none`.
frames	INT	Total number of frames (1 for still images).
width	INT	Output width after any resize.
height	INT	Output height after any resize.
frame_rate	INT	Frame rate of the source (or the forced rate if set).
audio	AUDIO	Extracted audio track. Silent if the file has no audio.
is_video	BOOL	True if the loaded file is a video or animation, False for still images.

Load & Resize Video

Same as Load & Resize Media but restricted to video and animation file types.

Inputs / Outputs

Same as Load & Resize Media, minus the is_video output.

Load & Resize Image

Same as Load & Resize Media but restricted to image and animation file types. No frames, frame_rate or audio outputs.

Outputs

Name	Type	Description
IMAGE	IMAGE	Loaded image as a tensor. `None` if file is `none`.
width	INT	Output width after any resize.
height	INT	Output height after any resize.

Resize Modes

All three loaders share the same resize pipeline, available via the resize dropdown:

Mode	Description
off	No resize — load at original dimensions.
scale dimensions	Scale to exact `width × height`. Optional center crop to avoid stretching.
scale by multiplier	Scale both dimensions by a float multiplier.
scale longer dimension	Scale so the longer side equals the given size, preserving aspect ratio.
scale shorter dimension	Scale so the shorter side equals the given size, preserving aspect ratio.
scale width	Scale to a specific width, preserving aspect ratio.
scale height	Scale to a specific height, preserving aspect ratio.
scale total pixels	Scale to a target megapixel count.
make divisible by	Round dimensions to the nearest multiple (e.g. 16 for WAN).

All modes include a divisible_by option and separate scale method selectors for upscaling and downscaling:

Scale Method	Best for
nearest-exact	Fastest, pixel art / sharp pixel edges
bilinear / bicubic	General purpose
area	Downscaling — sharp, minimal aliasing
lanczos	Upscaling — smooth, good detail retention
mitchell-netravali	Sharp upscaling with minimal ringing
bilinear (antialias) / bicubic (antialias)	Smooth downscaling with anti-aliasing
nvidia-rtx-vsr	AI upscaling — requires an NVIDIA RTX GPU and the nvidia-vfx package

Subgraph Labels

Assigns display labels to up to 10 subgraph ports. Experimental — requires subgraph support in your ComfyUI version.

Simple Title

A display-only node showing a text label in the graph. Useful for annotating sections of a workflow.

Debug Any

Displays any value as a text preview below the node. Primitives are shown as-is; complex types are serialized to JSON.

Preview Any

Displays up to 16 values simultaneously as inline text previews. For image tensors, shows a summary (N images, WxH) rather than rendering the images.
