unbagrnd

Overview

unbagrnd is a background-removal app that processes images locally on desktop, with manual editing tools and a self-hosted API for image workflows. It suits people who want open-source software and control over where their images are processed. Its trade-off is practical: platform install warnings and API defaults deserve attention before you build it into a workflow.

Key features

The desktop app uses ONNX Runtime to remove backgrounds on-device. It says its only network request is a one-time model download; images, filenames and metadata are not sent anywhere, and it has no analytics, update checks or telemetry. That is a strong fit for privacy-conscious editing, though the model download means the app is not entirely network-free from first install.

You can process one image or a folder, with live before-and-after previews as files finish. Settings offer several models to balance speed and accuracy, beginning with a 43 MB default. This flexibility is useful when throughput or output quality matters, but the choice also asks users to decide which trade-off suits their work.

Editing tools let users brush to erase or restore parts of a subject, undo and redo changes, then add a solid-color background and an on-device drop shadow. The app predicts a foreground mask on the CPU, composites it with the original pixels and saves a PNG. That covers straightforward cutouts and simple replacement backgrounds; the described output is PNG rather than a broader set of formats.

The maker also documents a Docker-capable self-hosted REST API with single-image and batch endpoints. Images are processed in memory and discarded rather than written to disk or logged; SQLite stores API-key metadata only. Defaults cap uploads at 20 MB per image, batches at 10 images and each API key at 60 requests per minute, so larger or busier jobs may need a different workflow.

Pricing

unbagrnd costs nothing. Its sole plan includes batch processing, API access, background replacement and manual editing tools, with no paid tiers or usage limits. That makes it a clear option for individuals and teams who can run the software themselves and do not need a metered service. There is no free trial because the product is free; the meaningful constraints are operational, including the API's default request and upload limits.

Platforms

unbagrnd is available for Android, Linux, macOS and Windows, alongside API and self-hosted options, with desktop and mobile supported. Installation calls for extra care: the macOS build is not notarized, the Windows installer is not code-signed, and the Android APK is not on Google Play. Those caveats may make it a poor fit for users who require store distribution or signed installers.

Who it's for

Choose unbagrnd if local image processing, open-source licensing and freedom from usage charges matter more than a polished, centrally hosted service. It is especially compelling for users processing folders or building a self-hosted API workflow. Look elsewhere if you need a signed installer, a Google Play app, or API defaults that accommodate larger uploads or batches without adjustment.

Pros and cons

Pros

• Local desktop processing: Images, filenames and metadata stay on-device, with no analytics or telemetry.
• No usage charges or quotas: The MIT-licensed product has no paid tiers or usage limits.
• Useful workflow coverage: Folder processing, live previews, manual mask corrections and background replacement serve more than one-off cutouts.
• Self-hosted API: Single-image and batch endpoints offer an option for integrating background removal into a controlled setup.

Cons

• Installer caveats: macOS is not notarized, Windows is not code-signed, and Android distribution is outside Google Play.
• API defaults constrain jobs: Uploads are capped at 20 MB, batches at 10 images and requests at 60 per minute per key.
• PNG output: The described save format may not suit workflows that require other export formats.

Verdict

unbagrnd is the right choice for users who want local, open-source background removal with batch processing and a self-hosted API, all without usage fees. Its strongest reason to choose it is the combination of on-device privacy and unrestricted use; its strongest reason to look elsewhere is the combination of unsigned or non-notarized installs and API defaults that may need checking against your workload.
