When to use ComfyUI

Use this adapter when local control, private inputs, or a custom graph justify the maintenance work. It is not a shortcut to finished pixel art. The tested SDXL plus Pixel Art XL graph can establish a composition, but its output still needs native-grid recovery, a final palette, and human review.

If the main goal is the shortest path to usable pixel art, compare PixelLab and Retro Diffusion first. Choose ComfyUI when owning the workflow is worth the extra model testing and cleanup.

Quality-first workflow

1. Generate two to four candidates at the model's normal working size.
2. Reject missing subjects, weak silhouettes, and bad composition before doing any cleanup.
3. For isolated art, remove the background at full resolution.
4. Run pixelkiln refine to recover one native pixel per detected cell and apply the final project palette. Start with 16–32 colors and no dithering.
5. Review the native file at 1× and an integer zoom, then record it with pixelkiln refine approve.
6. Run pixelkiln refine check before packaging or release.
7. Keep the smallest clear result. Start with 48–128px native components and compose larger scenes from accepted parts.

Stop after step 2 when the image misses the brief. Background removal, pixel-grid recovery, and palette reduction cannot restore a missing building or repair a weak composition.

PixelKiln automates generation, candidate review, cache recovery, grid reconstruction, palette checks, and the approval record. Background removal stays in the ComfyUI graph. A person still decides whether the image is good. Do not package it until pixelkiln refine check passes.
