AyeSpy review
A practical self-hosted choice for Selenium teams comparing browser screenshots.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AyeSpy is a command-line visual regression testing tool for teams that need to compare web interface screenshots across repeatable browser runs. It captures pages through Selenium WebDriver, compares new images with baselines, generates visual-difference reports, and can fail builds when differences are detected. Its strongest fit is a self-hosted Selenium team that wants an open-source workflow rather than a hosted visual testing service.
The testing surface is broader than simple screenshot comparison. AyeSpy supports Chrome and Firefox, Selenium Grid, configurable viewport sizes, and mobile device emulation through Chrome. Teams can prepare pages before capture with scripts, waits, cookies, and selectors, while element cropping, hiding, and removal help focus comparisons on relevant content. Branch-specific screenshot runs also support parallel development workflows. Docker integration and the npm package format fit environments that already standardize browser automation around those tools.
Storage and execution remain part of the team’s infrastructure responsibility. Optional Amazon S3 remote image storage can support shared baseline and screenshot handling, while Docker and Selenium Grid can provide repeatable execution environments. AyeSpy is a focused choice for engineering teams comfortable maintaining self-hosted browser testing and wiring visual checks into CI/CD. Teams looking for a managed service, a broader ecosystem beyond Selenium, or a documented approval workflow should consider a different product.
