Argos

Argos provides an open‑source platform for visual regression testing that integrates with modern development workflows. It captures screenshots of UI components during automated runs, compares them against baseline images, and reports pixel‑level differences so teams can detect visual bugs early in the pipeline. The system is designed for engineering groups that need to maintain consistent, pixel‑perfect interfaces across browsers and devices.

The tool offers a web dashboard where test results are visualized, allowing developers and designers to review changes, approve updates, or reject unintended modifications. Collaboration features let team members comment on findings and track the history of visual diffs, supporting coordinated quality assurance without leaving the CI environment.

Argos is distributed under a stable release, includes documentation and example integrations, and welcomes contributions via its public repository. It targets projects that already use continuous integration and want a lightweight, self‑hosted solution for automated UI verification.
