When to stay with ComfyUI
Documented strengths from our ComfyUI review — switching isn't always the right call:
- Core engine is GPL-3.0 open source and free forever on your own hardware, with no feature gates or trial period
- The node graph exposes the full inference pipeline — sampler, scheduler, CFG, model chain — instead of hiding it behind a prompt field
- 5,000+ community extensions totaling 60,000+ nodes, and new open models typically get support shortly after release
