ComfyUI
Node-based workflow engine for Stable Diffusion and modern image/video generation models
Overview
ComfyUI provides a graph/node-based interface for building and running Stable Diffusion pipelines with fine-grained control over every step. It supports SDXL, SD3, Flux, ControlNet, IP-Adapter, and video generation models. Its modular design and API make it popular for production automation and as a backend for other tools.
Where it falls short of OpenAI API
- Steep learning curve; node graphs become complex quickly
- No user management or auth out of the box
- Community custom nodes can conflict and break workflows
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
