Top comment
Hey everyone 👋 — I'm the maker of SmartDevBox, and I'm really excited to share it here today. The idea came from a simple frustration: every time I hit a JWT, a Base64 blob, a timestamp, or a minified JSON in a log, I'd open a different tab for each one. jwt.io here, jsonlint.com there, some random Base64 decoder somewhere else. It added up to dozens of bookmarks and constant context-switching. So I built SmartDevBox — a single box where you just paste and it figures out the format for you. 91 tools across encoding, formatting, conversion, generation, inspection, and text utilities. Auto-detection runs in under a second with a two-tier confidence system, so it either fires automatically or shows you a smart suggestion chip. A few things I'm particularly proud of: 🔒 100% client-side — your tokens, certs, and secrets never leave your browser 🧩 Plugin system — you can register your own custom tools with a detector + transformer function ✈️ Works offline — it's a PWA, so once loaded it runs without internet (minus the optional AI mode) 🆓 Completely free — no sign-up, no rate limits, no paywall Happy to answer any questions — and would genuinely love your feedback on what tools are missing or what could feel snappier. Thanks for checking it out! 🙏
