About

Full stack engineer with a few years' experience building web apps. I care about developer tools that respect privacy building JSON Workbench, a browser-based suite of JSON/JWT/data tools where everything runs locally and nothing gets sent to a server. Always exploring new tool ideas and open to feedback from other builders.

JSON Workbench - Privacy-first JSON & JWT tools that run in your browser

JSON Workbench started because I kept hitting the same wall: pasting real data (tokens, configs, payloads) into random online tools felt risky, and I never knew where that data actually went. So I built a set of dev tools, JSON formatter, JWT debugger, CSV to JSON converter, Excel compare, and more, that run fully in your browser. Nothing gets uploaded, nothing touches a server. If you handle sensitive JSON or JWTs at work and can't paste them into cloud tools or LLMs, this is built for you.
