Stable Diffusion Workflows: Turning ComfyUI into an Image API

Mon, 02 Jun 2025 08:00:00 +0000

ComfyUI is usually sold as a node editor — a sprawling graph of boxes and wires you drag around to build a Stable Diffusion pipeline. That’s how most people meet it, and it’s genuinely the most flexible front end for local image generation. But the canvas is the boring part. The interesting part is that everything you build on it is just a JSON document, and ComfyUI happily executes that JSON over an HTTP API. Once you realise that, ComfyUI stops being a toy you click and becomes an image-generation service you can call from anything — a cron job, a build pipeline, a webhook handler.

The first time you open ComfyUI, you will hate it. There’s no friendly prompt box waiting for your words, no big orange Generate button — just a tangle of boxes connected by coloured spaghetti, like someone wired up a modular synthesiser and walked off. I closed it the first time too. Then I went back, because the people producing the most consistent, repeatable, genuinely controllable images locally were all using it, and there’s usually a reason a difficult tool refuses to die.
