Website Inspector

Website Inspector v1.2 — The Ultimate Developer Toolkit.

Stop juggling five different extensions. Website Inspector combines the best features of CSS visualizers, tech sniffers, and SEO analyzers into one lightning-fast, beautifully designed tool.

Built with a premium Material Design 3 (M3) Dark Theme and hardware-accelerated animations, it feels like a native, high-end part of your browser.

✨ KEY FEATURES:
