HandyTools is a collection of 15 free developer and productivity tools — JSON formatter, regex tester, base64 & URL encoders, UUID & password generators, unit & color converters, and more — all wrapped in a nostalgic Windows 95 interface. Everything runs 100% in your browser: no signup, no ads, no tracking, nothing uploaded to a server. Just open a tool and go.
Hey Product Hunt 👋
I built HandyTools because I was tired of googling "json formatter," landing on a bloated site covered in ads, dismissing three cookie banners, and waiting for 40 trackers to load — just to indent some JSON.
So I made the opposite: 15 tools I reach for constantly, all in one place, all running entirely in your browser. Nothing is uploaded anywhere, so it's safe to paste sensitive data. No signup, no ads, no tracking.
And because building yet another minimal flat-design tool site felt boring, I wrapped the whole thing in a Windows 95 interface — beveled buttons, a tree sidebar, a working taskbar and clock, the whole thing. It made it genuinely fun to build, and hopefully fun to use.
What's inside:
• Developer — JSON formatter, base64, URL encoder, regex tester, UUID generator, markdown preview
• Text — word counter, case converter, lorem ipsum
• Generators — password generator, color converter (HEX/RGB/HSL)
• Math & dates — unit converter, percentage calculator, age calculator, unix timestamp converter
It's vanilla HTML/CSS/JS with zero dependencies, and it's open source: https://github.com/Novaro1/handy...

Would love your feedback — and I'm taking requests for which tool to add next!

love the win95 vibe, super charming and the no signup thing is honestly such a relief. one thing though, could you add a diff tool for comparing two json or text blocks side by side? would make it way more useful when i'm debugging api responses

The Windows 95 aesthetic is genuinely charming and makes these boring utilities feel fun again. Loved that the JSON formatter works instantly with no account or upload.

The Windows 95 styling is such a fun touch for something that otherwise could have looked like every other dev tools page. Love that it actually works offline too, not just pretending to.

the Windows 95 skin is such a charming touch, especially for tools that usually feel sterile. love that everything just runs locally with zero friction.
