Hey Product Hunt 👋 I’m Manoj, the maker of Dev Utility Toolkit. As a developer, I kept jumping between multiple tools just to handle simple tasks like formatting JSON, decoding JWTs, encoding URLs, or comparing text. It was slow, cluttered, and sometimes risky when working with sensitive data. So I built a fast, minimal, privacy-first toolkit where everything works instantly in your browser — no login, no tracking, no server calls. 🧰 What you can do with it: 🧹 JSON Formatter 🔗 https://tools.manojcoder.in/json... Beautify and format messy JSON instantly Makes nested data easy to read and debug Perfect for API responses and logs 🔐 JWT Decoder 🔗 https://tools.manojcoder.in/jwt-... Decode JWT tokens (header & payload) View claims like exp, iat, iss, etc. Helpful for debugging authentication flows 🔗 URL Encoder / Decoder 🔗 https://tools.manojcoder.in/url-... Encode special characters safely for URLs Decode encoded strings instantly Useful for query params & API requests 🆚 Text Compare (Diff Tool) 🔗 https://tools.manojcoder.in/text... Compare two texts side-by-side Highlights differences clearly Great for debugging configs, responses, or code changes ⚡ What makes it different? 🔐 100% client-side → your data never leaves your browser ⚡ Instant performance (no API calls) 🎯 Clean, distraction-free UI 🧰 Multiple essential tools in one place 🙌 Who is this for? Developers working with APIs QA engineers & testers Backend & DevOps engineers I’d genuinely love your feedback 🙏 What tools should I add next — Base64, Regex tester, API tester? Thanks for checking it out ❤️
