withoutBG Open Weights as a free, open-source remove.bg alternative
remove.bg is a paid cloud service. withoutBG Open Weights is open weights under Apache-2.0, so commercial use is allowed. It runs on your own machine (pip install withoutbg), offline, with no upload and no per-image cost. On Bench v0 it ranks #3 of 14 by accuracy (MAE).
remove.bg is not in Bench v0, so there is no score against it. See withoutBG Open and remove.bg side by side, or compare all remove.bg alternatives.
Quick take
- Best for: General product and portrait cutouts when you want a maintained open stack
- Avoid when: You need the absolute hardest hair/fur cases — try Pro Model API
- Notes: Same kit as the managed Pro Model API shape when you upgrade later.
