node-based visual workflowComfyUI: uses, limits and practical trial
ComfyUI is an open-source generative workflow engine organized into nodes. Comfy also provides cloud execution: a visual workflow does not necessarily compute on your own machine.

Suitable tasks
Build repeatable processing chains, reuse settings and understand how generation steps connect. It fits a need for control more than a one-off request.
Limits and checks
Models, additional nodes and versions are dependencies. Check origins, licences and memory requirements. Downloaded workflows can require components your installation lacks.
A repeatable trial
Start with a simple workflow and an authorized image. Save the graph, versions and parameters. Run it again, then change one parameter to observe its effect. Check a colleague can reproduce the steps.
How to decide
Choose it when reuse and control justify setup time. A simpler interface can reduce dependency management for a single task.
Frequently asked questions
Are ComfyUI and Comfy Cloud identical?
The engine and hosting service are distinct. Check where your workflow executes.
What should I retain for reproduction?
The workflow, inputs, parameters, model and node versions. Some operations may remain nondeterministic.
