Delta-QA — All Articles & Tutorials

This page gathers articles directly focused on Delta-QA: release announcements, step-by-step tutorials, feedback from teams that have deployed it, in-depth posts explaining our technical choices (engine architecture, capture via embedded Chromium, perceptual diff algorithm, deterministic comparison). The goal is not to convert, but to document — for current users who want to get the most out of the tool, for evaluators who want to understand how it actually works, and for the QA community following the evolution of the visual testing market.

You will find the getting-started guides for macOS and Windows, recipes for specific use cases (testing an SSO-authenticated site, managing a suite of several hundred pages, automating a weekly UAT run), honest comparisons against Percy, Chromatic, Applitools or Playwright snapshot, and posts that explain the trade-offs — why we set aside certain requested features, what the free beta covers and what it leaves out, how we shape the roadmap. Delta-QA is in active beta, and this page reflects its evolution week by week rather than a frozen narrative. Feedback submitted via the feedback page directly shapes the topics covered here.
