Visual Regression Tracker
Visual Regression Tracker compares submitted screenshots with accepted baselines to flag unexpected visual changes. It keeps baseline history and lets teams exclude image regions from comparisons. Projects can choose among Pixelmatch, Looks-Same, Odiff, and a VLM comparison provider. The review dashboard supports side-by-side, diff, scrubber, and onion-skin views, with one-click approval. Feature branches inherit the main branch baseline until a change is approved, and builds can post commit status to GitHub or GitLab. The project lists agents for Playwright, Cypress, CodeceptJS, and Robot Framework, plus JavaScript, Java, Python, and .NET SDKs; its REST API supports other languages. A standalone JAR can compare PDFs as well as images. Deployment is self-hosted using Docker images, and the project says this keeps data inside the user's intranet. The documented screenshot upload payload limit is 20 MB. Each project has one owner; members can view snapshots and approve changes, while some actions are owner-only. It is open source under Apache-2.0.
