Fully offline

Krita plugin that wires ComfyUI into a real digital-art workflow. Inpaint, outpaint, upscale.

What it is

For digital artists who already live inside Krita and want Stable Diffusion as a native brush, not a separate chat interface. This plugin bridges to a local ComfyUI server, letting you inpaint, outpaint, and region-generate directly on your canvas with full layer and mask support. It works with SD1.5, SDXL, or Flux.1 on Linux, macOS, or Windows, requiring at least 8 GB VRAM. The tradeoff: you need ComfyUI running separately, and the setup assumes familiarity with Krita’s existing tools. Best for artists who want SD integrated into a real painting workflow, not a wrapper.

✓ Strengths

  • +First-class integration with Krita's brush + layer system
  • +Inpaint / outpaint / live workflow
  • +Plays nice with custom ComfyUI nodes

△ Caveats

  • −Requires a separately-installed ComfyUI server
  • −Steep learning curve if you don't already know Krita
