Open-source HEISS UI v0.18 lets you run ComfyUI without workflows: built-in MOSS Image and Flux3 support (with a Flux3 prompt enhancer), auto-install of missing VAEs/text encoders/nodes, zero-setup video gen, reference images and inpainting, custom aspect ratios, Docker support, and a phone-friendly LAN UI with favorites, search, prompt history and LoRA stacks. Setup takes about 2 minutes.
