I’m looking for a library or tool that can facilitate the **conversion of models/pipelines between Hugging Face Diffusers and ComfyUI** formats.

Does anyone know of any actively maintained projects or methods that achieve this conversion?

Something that seems like it should exist, but doesn’t.😅  
As far as I know, I’ve never heard of a library or framework-level Diffusers ↔ ComfyUI / WebUI converter…  
ComfyUI → Diffusers is easy though… (using `from_single_file()` and such)

[For some architectures (SDXL, SD 1.5, SD 2), there are official Diffusers → ComfyUI conversion scripts you can use, but in most cases, you’ll end up having to create or find your own conversion script](https://huggingface.co/datasets/John6666/forum2/blob/main/convert_diffusers_comfyui_single_safetensors_1.md).
