ComfyUI-RMBG
Advanced ComfyUI background removal and segmentation custom node.
Precision background removal and object segmentation using multiple state-of-the-art models.
ComfyUI-RMBG is a specialized suite of custom nodes designed for complex image masking, background removal, and segmentation tasks directly inside ComfyUI. It suits photographers, compositors, and AI artists needing fine-grained control over subject isolation.
What it is
The node pack integrates multiple heavy-duty segmentation models like RMBG-2.0, SAM3, BiRefNet, and GroundingDINO to handle complex tasks like fashion, hair, transparent objects, and text. It includes tools for image stitching, mask overlaying, resolution selection, and instant GPU VRAM release.
Who it's for
It suits experienced ComfyUI users and digital retouchers who require granular masking capabilities beyond standard tools. It does not suit beginners unfamiliar with node-based workflows or those without dedicated GPU hardware.

Our honest verdict
What's great
- Combines numerous leading segmentation models into a single ComfyUI interface
- Includes dedicated VRAM unloading toggles to prevent out-of-memory crashes
- Supports native Apple Silicon (MPS) GPU acceleration for macOS users
- Features specialized BiRefNet fine-tunes for transparent objects and text
Where it falls short
- Requires an existing working installation of ComfyUI to function
- Downloading and running multiple heavy models like SAM3 and BiRefNet demands substantial VRAM
- Steep learning curve due to the vast array of node parameters and model options
Pricing & license
The tool is entirely free to use under its open-source license. The only cost is running it yourself on local GPU hardware capable of handling deep learning segmentation models.
