QALens — Discover APIs & Page Locators

About

QALens helps QA Engineers and Business Analysts understand what APIs a web
application actually uses — without needing to read code or operate
DevTools, Burp Suite, or Postman.

WHAT IT DOES
• Captures every API call (fetch/XHR) made by the page you're testing:
  method, full URL, status code, response time, headers, and bodies.
• Generates ready-to-use Playwright and Selenium element locators for any
  interactive element on the page, so you can drop them straight into your
  test scripts.
• Exports captured endpoints as CSV or JSON — handy for building a data
  mapping document or sharing findings with developers.

PRIVACY, BY DESIGN
• 100% local. QALens has no backend — nothing it captures is ever sent
  anywhere. Everything lives in your browser's local storage.
• Sensitive values (Authorization/Cookie headers, password/token-like body
  fields) are automatically redacted before they're ever stored.
• Pause anytime, clear data anytime, and data auto-clears when you navigate
  away or close the tab.

WHO IT'S FOR
QA Engineers, Business Analysts, and anyone who needs to map an application's
API surface but isn't comfortable with developer tooling.
