A lightweight Chrome extension for fast, deterministic web automation setup (Open Source & Free).
It records a filtered network HAR while letting you right-click to save labeled XPaths for clicks, inputs, selects, extracts, and waits — even on messy UIs. When you're done, it exports the HAR alongside a structured JSON step list ready to wire into Playwright or Selenium.
Useful as a fallback when browser agents get flaky, and handy for reverse-engineering unfamiliar web apps.
