What AyeSpy is

AyeSpy is a self-hosted visual regression tool that checks web pages for visual changes. It captures screenshots and compares them with baseline images; differences fail the build and produce a report. The README lists Firefox and Chrome support, and Amazon S3 storage integration. It recommends Selenium Docker images for browser automation and provides an example using a Selenium Grid URL. Scenario settings can crop captures to a selector, hide or remove elements, wait for elements, set cookies, and run scripts before capture. The `--branch` option stores branch screenshots in a separate S3 subdirectory; the README recommends setting a lifecycle policy to remove them when they are no longer needed. Mobile emulation accepts a device name but works only with Chrome. The README says 40 comparisons can run in under a minute with the correct setup. AyeSpy is open source under a BSD 3-Clause license and is maintained by The Times Tooling team. It is most suited to loading a page and capturing it; complex journeys such as checkout flows reduce its value. Switching contexts to iFrames is not supported. The listed plan is free, with no paid plans or usage limits stated.

Good

  • Screenshot differences fail builds and generate a report.
  • Supports Firefox and Chrome.
  • Scenario settings offer several capture controls.
  • Screenshots can be stored through Amazon S3.
  • Open source under a BSD 3-Clause license.

Watch out

  • Switching contexts to iFrames is unsupported.
  • Mobile emulation works only with Chrome.
  • Complex journeys reduce its value.

Who it suits

AyeSpy suits teams that want self-hosted screenshot comparisons in a build workflow, especially for pages with straightforward loading and capture. It is less suited to complex setup journeys or pages that require iFrame context switching.

Verdict

AyeSpy focuses on screenshot-based checks and offers configurable capture scenarios for build workflows. Its stated limits around iFrames and complex journeys matter when choosing it for a site.
