AX Tree Exporter

Extract and export the complete Computed Accessibility Tree of any webpage into a clean, parseable JSON file with a single click. What does it do? While standard JavaScript only has access to the standard DOM, screen readers and search engines (like Google Bot and AI Answer Engines) rely on the browser's Computed Accessibility Tree (AX Tree). "AX Tree Exporter" connects directly to the Chrome DevTools Protocol (CDP) to capture the exact accessibility node hierarchy of your current tab—including roles, ARIA attributes, computed names, and states—and instantly downloads it to your local machine as a structured JSON file. Why should you install it? Deep Accessibility (A11y) Audits: Stop inspecting nodes one by one in the browser console. Get a bird's-eye view of the entire page structure to easily spot missing <h1> tags, ghost links, or redundant Alt texts. SEO & AEO Optimization: See your website exactly how Answer Engines and AI crawlers see it. If your semantic structure is clean and well-labeled in the AX Tree, your content is primed for better ranking and AI-generated answers. Ready for QA & Reporting: Use the exported JSON files to feed your automated testing scripts, track accessibility compliance over time, or attach definitive proof to bug reports for your engineering team. Lightweight & Secure: Zero bloat, no background tracking, and runs strictly locally. It only requests DevTools access the moment you click the extension icon. Who is this for? Frontend Developers, Accessibility Specialists, QA Engineers, and Technical SEO Experts who need raw, accurate data to improve web experiences.
