Summary
In ComfyUI, every step of a generation pipeline, from loading a model to sampling and upscaling, is a node you connect on a canvas, and the whole graph can be saved as JSON and reused. The README lists broad native support for image, video, audio, 3D and text models, a local API, and installs for Windows, Linux and macOS across NVIDIA, AMD, Intel and Apple Silicon hardware. The core software is free and, per the README, runs offline. Comfy Cloud is a separate paid hosting service with plans from $20 a month, and optional API nodes for closed models consume credits. Model weights you load keep their own licenses.
Bottom line: Pick ComfyUI for detailed, reusable control over generation pipelines on your own hardware; expect a node-graph learning curve and check each model's license.

Pros
- Free GPL-3.0 software that runs locally on Windows, Linux and macOS across several GPU vendors.
- Every pipeline step is a visible node, and workflows save as reusable JSON.
- A local API lets applications run saved workflows.
Cons
- The node-graph interface takes time to learn for people new to diffusion pipelines.
- Model weights and third-party custom nodes carry their own licenses to check separately.
- Local use depends on your own hardware; hosted Comfy Cloud and API nodes cost extra.

What ComfyUI is
ComfyUI is a node-graph application for building generative media pipelines. Its GitHub README describes a visual canvas where model loaders, samplers, conditioning and post-processing steps are wired together as nodes, for image, video, audio, 3D and text workflows. Workflows save as JSON, and the README says a complete workflow can be recovered from supported generated media. It also documents a local API for calling workflows from other applications.
Free local software
The application is released under the GPL-3.0 license. It runs on Windows, Linux and macOS through a desktop app (Windows and macOS), a portable Windows build or a manual install, and the README lists support for NVIDIA, AMD, Intel, Apple Silicon and Ascend GPUs. According to the README, the core runs offline and downloads nothing unless you ask it to. Optional paid API nodes reach closed hosted models; an --offline flag disables them.
Optional paid hosting
Comfy Org also sells Comfy Cloud for people without suitable local hardware. On October 17, 2026, its pricing page listed Standard at $20/month, Creator at $35/month, Pro at $100/month on monthly billing, with lower yearly rates. Team pricing varies by a shared credit commitment, with five tiers from $200 to $2,500 per month; $700 is one slider setting. Enterprise pricing is custom, and new users can try five GPU runs. Partner node usage draws on the same credit pool.
Licenses are layered
GPL-3.0 covers ComfyUI itself. The models you load, such as Stable Diffusion, Flux or Wan, have their own licenses, and third-party custom nodes may carry their own terms. Check those separately before commercial use.
Who it suits
ComfyUI suits people who want detailed control over each step of a generation pipeline and are comfortable working in a node graph, plus developers who want to run workflows locally through an API.
