ComfyUI and verl share 3 technologies: einops, transformers, and av. Both are written in Python.

- [Comfy-Org/ComfyUI](https://seerepo.com/r/Comfy-Org/ComfyUI): The most powerful and modular diffusion model GUI, api and backend with a graph/nodes interface. The fastest local inference engine in the world.
- [verl-project/verl](https://seerepo.com/r/verl-project/verl): verl/HybridFlow: A Flexible and Efficient RL Post-Training Framework
