Roborazzi vs Screenshotbot

Roborazzi is an open-source library for screenshot testing in JVM-based Android integration tests. It records images, compares them with saved baselines and can fail verification when a screenshot differs. Through Robolectric, Android tests can run as JVM tests without a device or emulator. Capture options include Jetpack Compose nodes, Espresso views, Android Views and Compose lambdas; the library can also create screenshot tests for Compose previews and common Compose Multiplatform previews. It supports Compose Desktop and JVM preview tests, rendering images with the host’s Skia, while Compose Multiplatform iOS support is experimental. Gradle tasks cover recording, comparison and verification, and the project documents GitHub Actions workflows for screenshot checks in CI. An IDE plugin shows test screenshots in IntelliJ IDEA and Android Studio. Optional capabilities include UI-tree JSON output, accessibility checks, animated GIF or APNG capture, and experimental AI image assertions. Roborazzi is free, available on Maven Central and licensed under Apache License 2.0. It has no direct Bazel support, and graphics may render differently across operating systems.

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.
