ComfyUI
A node-graph interface for local image generation, where you build a workflow by wiring together nodes. It is the most flexible and powerful local image tool, quick to support new models, and it saves workflows as reusable JSON.
Strengths
- Extremely flexible node-graph workflows, reusable and shareable
- Fast to support new models, including FLUX and video
- A huge ecosystem of custom nodes
Weaknesses
- The node graph has a real learning curve
- Powerful but not the gentlest tool for casual, occasional use
- Results depend heavily on building a good workflow
