Hey Product Hunt! 👋 I built Web Developer Tools because I was tired of opening a different website every time I needed to format JSON, decode a JWT, inspect headers, test CSS, generate a UUID, check accessibility, analyze SEO, or debug a page. So I started putting those utilities into one Chrome extension. Today, WDT has 500+ tools across HTML, CSS, JavaScript, Network, SEO, Accessibility, Security, Performance, Images, Storage, Data & more. The part I'm especially proud of: the tools run locally on your device — no server-side processing and no tracking. I'd love to hear from developers here: 👉 What's the developer utility you use most often? And if you try WDT, I'd genuinely love to know which tools you find useful — or which ones are missing. 🚀
