Your offline developer Swiss Army knife — Base64, JWT decoder, URL encoder, JSON formatter, UUID generator, regex tester, hash calculator, and more. 100% private. 🔗 Try it free: https://microsaas-lab.vercel.app/devUtils The Problem Every developer has a browser bookmark folder of single-purpose tools: one site to decode JWTs, another to format JSON, another for Base64, another for UUID generation. Every time you use them, you're pasting potentially sensitive data — tokens, credentials, API responses — into third-party servers. And every one of those sites has ads, paywalls, or tracking. There's no reason any of these operations need to touch a server. Introducing DevUtils DevUtils bundles all the tools you reach for ten times a day into a single offline-first page. Every operation runs locally in your browser — Base64 encode/decode, JWT decode, URL encode/decode, JSON format/minify, UUID generation, regex testing, hash calculation, and more. No servers, no ads, no tracking. DevUtils is
