FunPack is a UI that unlocks novel conditioning and sampling enhancements, wires cutting-edge techniques and allows simple non-linear video montage - all while using regular ComfyUI backend. Graphs replaced with neat cards, get/set replaced with Linked inputs, and simple text fields leveled up to Composer - prefix, prompt, postfix, $variables, Ideas button, shortcuts and splits - for your prompting comfort.

[!IMPORTANT] FunPack is a hobby project maintained by a single person. It's crafted for my personal needs mostly, and I can't test every single possible variant of usage to confirm it's bug-free and working as intended. If you had found a bug or you want to request a new feature, feel free to add an entry to Issues - that would be the most appreciated.

v4 update and migration/seize of support notice

Preparation for the next milestone update v4.0.0 has been started and it is in progress.

Since v4.0.0 all updates will target ONLY Cutting Room editor. Nodes will receive updates but their compatibility and proper display inside regular ComfyUI frontend won't be guaranteed and/or tested.

Feel free to test and leave feedback regarding v4.0.0 by switching branch to "v4" via internal feature inside "Settings" -> "Updates and ComfyUI" -> "Switch branch".

Installation

FunPack is available on Comfy Registry and can be installed in any of these ways:

With comfy-cli: comfy node install ComfyUI-FunPack
With git, inside your ComfyUI/custom_nodes directory: git clone https://github.com/digital-garbage/ComfyUI-FunPack
With ComfyUI-Manager: Open Custom Nodes Manager, search for ComfyUI-FunPack, and click Install.

Dependencies

FunPack includes a requirements.txt file for its Python dependencies.

Install them with:

pip install -r requirements.txt

FunPack uses your existing ComfyUI/PyTorch install. The expected baseline is transformers >= 5.0.0

Intent

FunPack is provided under GNU General Public License V3, which gives you broad rights to use, modify and distribute the original/modified version of it as long as the original license text is included. FunPack places no limitations on types of content you can generate by using it, meaning both SFW and NSFW content are fine as long as you don't violate your local laws. GPLv3 does not grant you rights for such violations.

However, I do not endorse using FunPack and/or demonstrating it alongside morally and legally questionable/prohibited content, including:

Non-consensual explicit depiction of a real person;
Explicit depiction of minors;
Depiction of violence and gore targeted at a real person.

I do not provide support to users who use FunPack in such cases, and in case I detect it, any support will be immediately ceased.

Thanks for understanding.
