DOM Lens: Web Inspector

Understand the webpage you can see—by tapping it.

DOM Lens is a visual web inspector for iPhone and iPad. Open a URL, tap an element, and move from appearance to DOM and CSS without a Mac. It is made for designers, frontend developers, QA testers, and anyone learning how interfaces are built.

INSPECT BY TOUCH
• Live DOM, attributes, CSS selector, and XPath
• Matched CSS rules, specificity, and computed styles
• Box model for margin, border, padding, and content
• Page-wide CSS selector search with multi-element highlighting
• Live CSS editing with undo and redo
• Console logs and errors, plus JavaScript execution
• Network request metadata without collecting request or response bodies
• Page Audit for metadata, headings, Open Graph, JSON-LD, and missing alt text

BUILT FOR IPHONE AND IPAD
The touch-first element picker and tracking highlight make real pages easy to inspect. Use the stepped panel on iPhone or the spacious split view on iPad. A visible progress indicator shows page loading and analysis status. An included sample page lets you try the workflow offline. The interface is available in English, Japanese, Korean, Spanish, Brazilian Portuguese, French, German, and Italian.

AI DESIGN PACK — OPTIONAL ONE-TIME PURCHASE
Package the selected element’s annotated screenshot, DOM, CSS, box model, design tokens, Page Audit, and implementation brief as a searchable PDF, Markdown, and JSON. The files are structured for handoff to AI tools or teammates. Exports are generated on device with no usage limit.

PRIVACY BY DESIGN
Web sessions are non-persistent. Form values, cookies, storage, credentials, and network request or response bodies are excluded from exports. The websites you open still receive the ordinary web requests needed to load their pages.

Core inspection tools are free. AI Design Pack requires an optional one-time in-app purchase. There is no subscription.
