Paparazzi review
Open-source golden-image checks for Android Views and Compose, run through tests.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Paparazzi is an open-source Android library for rendering application screens in tests without a physical device or emulator. It is aimed at developers checking UI changes in Android Views and Jetpack Compose, with rendered screenshots saved as golden snapshot files that can be source-controlled. Tests can then compare later renders with those baselines, making the library relevant to teams that want visual regression checks in their Android test workflow. It supports both solo development and larger teams, but its scope remains Android UI rather than browser testing.
The snapshot workflow is its central strength. Paparazzi can configure device characteristics and themes for rendering, record screenshots, and verify subsequent output against existing snapshots. When verification fails, it generates image diffs to show the visual discrepancy, and an HTML report brings test runs and snapshots together for review. JUnit 5 test setup is supported as well. These features make it a fit where teams want visual checks attached to tests and source-controlled baselines, rather than a separate hosted service. The project description does not present a hosted testing service or paid tiers; the product is open source.
Paparazzi fits Android projects that can incorporate its Gradle tasks to run tests, record snapshots, and verify them. Teams should expect to manage the golden files and review diffs when output changes; the value depends on keeping those baselines aligned with intended UI updates. It is not the right choice for teams seeking cross-browser coverage or a hosted testing platform. Choose it for Android-focused screenshot verification and local test reporting; consider a broader visual testing product if browser testing is a core requirement.
