| Security | The AI assertion documentation advises passing API keys through environment variables rather than hard-coding them in code. | The privacy policy says Screenster uses encryption, firewalls, and SSL technology as security measures, while noting these do not guarantee against breaches. |
| Visual verification | Its Gradle tasks record, compare, and verify screenshots, and verification fails when an image differs from its saved baseline. | The service compares screenshots and page content against baselines to detect new, deleted, and changed UI elements. |

In their own words
Roborazzi
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.
Screenster
Screenster is a UI regression testing tool for automating tests of web interfaces. Its no-code recorder captures actions on web pages without requiring code, element IDs, checks, or assertions. Test runs can be compared with a baseline to identify new, deleted, or changed visual and page content. Smart selectors can find page elements after they move or change and adjust timeouts automatically. Users can also write JavaScript or Java tests against the Selenium API within Screenster. The locally installed server can run offline. Screenster says it stopped running its online servers after August 1, 2023, and made local use free without restrictions. The installation guide requires Windows and lists Windows 8, 8.1, 10, Server 2012, and Server 2016; local browser documentation lists Chrome, Firefox, and Internet Explorer. Plans include Free at free, Basic at $25 a month, Standard at $45 a month, and Premium at $75 a month, each billed per tester per month.
