Screenshotbot vs Visual Regression Tracker

Screenshotbot collects screenshots from existing screenshot tests and reports visual changes without requiring teams to re-record screenshots manually. It accepts outputs from Android, iOS, React Native, Flutter, Selenium, Cypress, PDFs, Kotlin Multiplatform, games, and other image-generating sources. Reports include image comparison tools, screenshot history, and a bisecting tool to help locate regressions. Masks let teams exclude selected image areas, such as timestamps or animations, from comparisons. Integrations update pull request or merge request checks and build statuses for GitHub, GitLab, Phabricator, Bitbucket, and Azure DevOps. It works with any CI framework and identifies context for services including GitHub Actions, GitLab CI, CircleCI, Bitrise, Netlify, and Azure DevOps. Slack notifications and task creation for Jira, Asana, Trello, Pivotal, and Todoist are also listed. Pay-as-You-Go costs $0.01 a month, billed per screenshot, and includes 10,000 free screenshots per month. Platforms include web, API, self-hosting, and desktop and mobile systems.

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.
