Free image first Comfy frontend: HEISS UI | New Release today
Now with Inpainting, run grouping and native upscale!
What it is:
- Image first-generation studio
- Works without workflows with almost any model (no setup)
- Support for custom workflows
- Video gen, reference images, and inpainting all work without setup
- Smart grouping of your images by similar prompts
- Automatically installs missing components (VAE, text encoders, nodes) it knows
- Use it from your phone over LAN, with a fully custom mobile UI
- Favorites, search, prompt history, LoRA stacks, and advanced settings
- Built to be graceful and not scream at you with errors 24/7
It’s built by me, and in my opinion it’s the best way to use Comfy 80% of the time.
Setup is about 2 minutes: give it a try.
New in v0.17:
- Inpainting + Custom-built in-painting workflows (Beta)
- Auto-grouping. Pictures from similar prompts stack themselves into a photo stack or cover flow once you stop working on them.
- Within-generation Native upscale
- Phone View improvements
- Discord to discuss Heiss and AI generation (join pls; I need feedback)
