HyHover | All-In-One Developer Toolkit

The world’s most powerful, privacy-first developer extension. Replace 10 disjointed, resource-heavy add-ons with one unified, SaaS-grade toolkit. HyHover brings you a suite of elite diagnostic and design utilities that you won't find grouped together anywhere else—even in paid tools. Built for frontend developers, UI/UX designers, and QA engineers who demand speed, privacy, and zero bloat. ★ WHAT MAKES HYHOVER UNMATCHED? (Features Paid Tools Don't Have) Bypass Frame Restrictions: Our Responsive Simulator temporarily strips header blockers (X-Frame-Options & CSP) strictly in your active tab. Preview any site side-by-side without proxy servers or proxy fees. DNS & WHOIS Lookup On-Page: Run nameserver, IP registry, and domain age analysis directly from the sidebar. No need to open third-party lookup sites. Offline-First Security: Zero telemetry, zero cloud uploads. Your screenshots, code injections, and metrics stay local on your machine. ★ 10 ELITE TOOLS IN A SINGLE WIDGET 1. DOM Inspector: Read dimensions, layouts, and styles with a simple point-and-click overlay. 2. Color Picker: Extract exact HEX/RGB/HSL values from any pixel on your viewport. 3. Assets Extractor: View and download all active images and SVGs in one clean list. 4. Smart Screenshots: Capture visible areas, selections, or full-scroll pages. Export to PNG or PDF. 5. Layout Rulers: Measure layouts and align elements with drag-and-drop guides. 6. Web Vitals Monitor: Check LCP, FCP, TBT, CLS, and connection timings in real time. 7.
