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
