- Run a check
Test automation readiness
Selector Checker
Paste a URL and get a 0–100 readiness score against the 10 selector strategies Lastest uses (data-testid, id, role, aria-label, text, css, OCR, and more). See which selectors work, which are brittle, and what to fix.
- Start practicing
Practice environment
QA Automation Playground
Eighteen hands-on exercises for Playwright, Selenium and Cypress - forms, dynamic waits, iframes, shadow DOM, drag & drop, deliberately flaky selectors and full e2e flows. Train your team or your framework on a site that fights back.
- Compare two URLs
Visual + DOM + a11y diff
URL Diff
Compare any two URLs side-by-side. Get a pixel-perfect visual diff (four variants), DOM, network, accessibility (axe-core + WCAG) and page-text differences in one report.
