Rembg

Rembg is an open-source tool for removing image backgrounds, made by Daniel Gatis. It can be used as a command-line tool, a Python library, an HTTP server or a Docker container. The README lists several options: choice of model (including u2netp, SAM with point prompts, and custom ONNX models), mask-only output, alpha matting, and colour decontamination for soft edges. It also supports batch folder processing with a watch mode, and a pixel-stream mode intended for use with FFmpeg on video frames. Optional cloud backends (withoutBG and Atlas Cloud) are available, and CPU, NVIDIA CUDA and AMD ROCm installs are supported through ONNX Runtime. It needs Python 3.11 to below 3.14. The project is MIT-licensed with 25,379 stars; the latest release is v2.0.87 (6 November 2026). No benchmark results are given in the text.
