TurboUtil: A Free, Offline-First Collection of Dev Tools That Run Entirely in Your Browser

Hey dev community! 👋 If you're tired of online tools that: Require uploading your sensitive JSON/JWT/data to some random server Track you with ads or analytics Break when you're offline (airplane mode, spotty Wi-Fi, remote work) ...then I built something for you. I created TurboUtil — a completely free, browser-based suite of developer utilities. Everything runs client-side in your browser — no data leaves your device, no servers involved, no sign-up, no limits. Why I Built This As a developer, I use JSON formatters, JWT decoders, regex testers, and ID generators daily. But most popular tools (jwt.io, jsonformatter.org, etc.) send your payload to their servers. Privacy concerns + occasional offline needs pushed me to create an alternative that's fast, secure, and always available. TurboUtil is 100% offline-capable (after the initial page load) and privacy-first by design.
