   Tooly▲5

   I kept opening online JSON formatters and getting buried in ads and popups. So I made a clean version with a few tools I actually use daily – JSON formatter with syntax highlighting, Base64 encoder/decoder, JWT decoder, text diff, and timestamp converter. Everything runs client-side. No tracking, no server calls, no signup walls. Built with React 19 and TypeScript. It's open source: https://github.com/chken007/tooly My 5-year-old helped name it. She insisted on "Tooly" and I couldn't argue with that logic. Open to feedback – especially if you spot bugs or have…

    JSONXMLKit▲13

    I built this because I was constantly switching tabs to format JSON or XML, or decode Base64 — and many of the tools I found were either bloated, sent my data to a server, or just didn’t support things like XPath or JSONPath. JSONXMLKit runs 100% in-browser, and includes: JSON and XML formatters Path search with JSONPath and XPath File-based Base64 encoder/decoder (images, PDFs, etc.) No login, no uploads. Just a set of quick, client-side tools I needed and decided to share. Feedback welcome!
