https://dev.to/toolbox4devs/i-got-tired-of-pasting-json-into-sketchy-websites-so-heres-one-that-doesnt-log-anything--172i <p>Every dev has that moment where you paste something sensitive into an online formatter and immediately think "wait, does that server just... keep that?"<br> I built toolbox4devs.com to solve exactly that. It's a set of everyday dev utilities that run 100% in your browser — nothing is sent to any server, ever.<br> What's there right now:<br> 🔧 JSON Formatter — validate, format, minify. Syntax errors highlighted instantly.<br> 🔄 JSON → Model — paste JSON, get C# classes or TypeScript interfaces out. Huge time saver.<br> 🔐 Base64 Encode/Decode — boring, essential, now private.<br> 🔗 URL Encoder/Decoder — query string wrangling without the guesswork.<br> 📋 Text Diff — compare two blocks line by line.<br> 🆔 UUID Generator — v4 UUIDs, single or bulk up to 100.<br> ...and a few more. No login, no sign-up, no ads, no paywall. Just open it and use it.<br> I'm adding tools regularly based on what devs actually reach for — would love feedback on what's missing.<br> 👉 toolbox4devs.com</p> privacy productivity showdev tooling toolbox4devs Wed, 11 Mar 2026 02:44:17 +0000 https://dev.to/toolbox4devs/a-browser-based-dev-toolbox-that-never-sends-your-data-anywhere-1i61 https://dev.to/toolbox4devs/a-browser-based-dev-toolbox-that-never-sends-your-data-anywhere-1i61 <p>Tired of pasting JWT tokens into random online decoders, so I built my own.</p> <p>Everything runs 100% in your browser — JWT decoder, JSON formatter, Base64 encoder, UUID generator.
