ComfyUI online without installing or a GPU
ComfyUI is an open-source app: you build a graph of nodes, but you run it on your own computer with a suitable GPU and install Python, models and nodes. The official Comfy Cloud costs from $20 a month. If you need results rather than your own setup, Mixer AI has the Canvas node board: it runs in the browser and you pay per generation.
