Dom Change Diff

DOM diff for two HTML snapshots of the same page or component, built for browser-automation scripts whose CSS selectors quietly break after a site redesign.

Overview

DOM diff for two HTML snapshots of the same page or component, built for browser-automation scripts whose CSS selectors quietly break after a site redesign. Send before_html and after_html plus the selectors your workflow watches, and get back per-selector added/removed/moved/attribute-changed status, stale DOM detection for targets that vanished, and selector stability hints: replacement selectors built from an element's id, data-testid, or aria-label so a broken automation step can self-repair. Use it as a browser workflow repair tool, a selector-stability checker, or a pre-flight check before re-running a scraping or RPA script against a site that may have changed.
