Roborazzi review
A focused, free open-source choice for Android screenshot regression testing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Roborazzi is an open-source screenshot-testing library for Android and Kotlin projects. It is designed for teams that need visual regression checks for Jetpack Compose, Espresso views, Android views, or Robolectric-based JVM tests. Screenshot capture also extends to composable lambdas and selected Kotlin Multiplatform targets. Its strongest fit is an Android engineering workflow where screenshot baselines belong alongside source code and automated tests, rather than in a hosted visual-testing dashboard.
The core workflow is organized around Gradle tasks for recording, comparing, verifying, and updating reference images. Roborazzi creates generated diff images, JSON results, and HTML reports, giving teams several ways to inspect visual changes. Robolectric support enables JVM screenshot testing with configurable device, locale, night-mode, and screen-size qualifiers. GitHub Actions workflows support storing, verifying, and comparing screenshots in continuous integration. Optional GIF and video recording, UI-tree JSON dumps, annotated images, and accessibility checks add useful debugging context around a failing visual test.
Roborazzi follows a free open-source model rather than paid tiers, which suits teams comfortable maintaining testing workflows through Gradle, Robolectric, and GitHub Actions. Its focus is also its main boundary: the product is specialized for Android and Compose UI instead of general cross-browser visual regression. Teams building Android applications and wanting code-centered baseline comparison should consider it a strong fit. Teams seeking a hosted service, broad browser coverage, or a wider visual-testing ecosystem should choose a tool aimed at those requirements instead.
