A growing collection of 32+ free online tools that run entirely in your browser. Nothing is uploaded, stored, or sent to a server. Open DevTools → Network tab → use any tool → zero outbound requests. That's not a privacy policy — it's architecture. Formatters, converters, security tools, and utilities — all client-side. No accounts, no cookies, no tracking, no paywalls. We're starting with dev tools, but any utility that can run privately in a browser belongs here. More coming.

Hey PH! 👋 I'm Bharat.
I built ZeroData Tools because I was tired of pasting sensitive data into online tools that quietly send everything to a server.
The fix: every tool runs 100% in your browser. No backend, no uploads, no accounts. Verify yourself — open Network tab, zero requests.
32+ tools today: JSON formatter, JWT debugger, password generator, cron builder, hash generator, secret scanner, and more.
This isn't just a dev toolkit — any utility that can work privately in a browser belongs here. More categories coming.
Would love your feedback:
→ What tools should we add next?
→ Any UX improvements?
Thanks for checking it out! 🙏
