Powerful node-based UI for Stable Diffusion
Pros
- ✓ Node-based workflow editor enables complex multi-step image pipelines
- ✓ More memory-efficient than A1111 WebUI; runs with less VRAM
- ✓ Active custom node ecosystem (ControlNet, IPAdapter, AnimateDiff, etc.)
- ✓ Workflow JSON files are portable and shareable
Cons
- ✗ Steeper learning curve than form-based UIs like A1111
- ✗ Node graph interface can become unwieldy for very complex workflows
