Hey Product Hunt! 👋 I built DevNestTools because I was tired of the same thing happening every time I needed a quick dev tool: search "json formatter," click a link, and end up clicking through three cookie banners and a newsletter popup before I even see the input box. So I built something simpler. Each tool does one thing: 🔹 JSON Beautifier — formats messy JSON, shows you roughly where it broke if it's invalid 🔹 QR Code Generator — no watermark, no account needed 🔹 Image Compressor — shrinks JPG/PNG/WebP without visible quality loss 🔹 Image to Base64 — for embedding small icons/logos 🔹 Device Dashboard — screen resolution, browser, OS — great for bug reports 🔹 Code Minifier — quick HTML/CSS/JS minification without spinning up Webpack The thing I care about most: everything runs entirely in your browser. Nothing gets uploaded anywhere — you can open your network tab and check for yourself. If you're pasting a JSON payload with API keys, or compressing an image with unreleased product shots, that data never leaves your machine. No signup, no ads-clutter, no "coming soon" placeholders — if a tool isn't built yet, it's just not listed. Would love your feedback — especially if there's a tool you keep needing and can't find a decent free version of. A few of the existing ones started exactly that way.
