Hey Product Hunt 👋 As a developer I was tired of bookmarking five different random sites just for JSON formatting, Base64 encoding, UUID generation, and hashing — each with different UX, ads, and unclear privacy practices. Developer Tool Box brings these into one place: JSON Formatter, Base64 Converter, UUID Generator, URL Encoder, and Hash Text so far, all running locally in the browser with no account needed. Every tool has a permanent URL, and I'm shipping new ones regularly (converter, web, crypto, and network categories are already live or in progress). It's open source (GPL-3.0) and part of the same free-tools family as EasyPDFNex, Easy Calculator Nex, and Easy Converter, built under Nexora Creation. This is still early — would love feedback on what dev utility you reach for most that deserves a spot here.
