Wraith is a Ruby CLI tool from BBC News that takes screenshots of webpages with a headless browser across different environments or points in time, then generates image diffs highlighting changed areas. It outputs diff PNGs, a change-percentage report, and an HTML gallery, and can fail CI builds when diffs exceed a threshold.
Use cases
- compare screenshots of staging vs production sites
- visual regression testing for responsive web pages
- detect unintended CSS changes after a deploy
- compare a website against itself over time
- screenshot specific components via CSS selectors
- run screenshot comparisons in CI pipelines
When to choose
- you need automated visual diffing of web pages at multiple screen widths
- you want a simple Ruby gem for screenshot comparison with CI exit codes
- you're maintaining a legacy setup already built around Wraith
When to avoid
- starting a new project - the repo is explicitly unmaintained and issues/PRs are not monitored
- you rely on PhantomJS/CasperJS, which are themselves deprecated
- you need actively supported visual regression tooling like Percy, BackstopJS, or Playwright screenshot tests
