Why hasn't ComfyUI been completely replaced by a more "modern" graphical interface until now? The reason is simple: instead of a few fixed buttons, it gives you a set of node workflows that can be freely disassembled, connected, saved, and reused. The official README always puts the graph / nodes / flowchart interface at the forefront, and clearly emphasizes that only the changed parts will be re-executed, and the generated results can also bring the full workflow back to the PNG. This idea determines that it is not the same thing as many "one-click image generation tools" at all.
Its real moat is not whether the interface is good or not
ComfyUI's interface is not very beginner-friendly, and everyone knows this. But once you start doing complex processes such as multi-model combination, local redrawing, upscaling, ControlNet, video, audio, and 3D links, the benefits of node workflows become more and more apparent. You can't just use the developer's preset operation path, but you can really build the process into your own production line.
Why do many people not want to change after learning?
Because its "degree of freedom" will slowly become an "asset". The workflows you have built, the PNGs you have saved, and the node links you have called up are not one-time results, but work results that can be repeatedly reused and continuously modified. The official also explicitly supports reloading workflows from generated PNG / WebP / FLAC, which is particularly attractive to heavy users.
But it's also not the best entry point for all
If you just want to quickly generate a few graphs, don't want to understand nodes, and don't want to deal with models and custom nodes, then the learning cost of ComfyUI will be high. It is more suitable for people who are willing to use the graph generation process as an "orchestrable system" rather than those who just want to produce results in a few clicks.

The official repository is currently GPL-3.0. For those who really value controllability in image workflows, ComfyUI is still an open source project that is difficult to bypass.
