JSON Workbench
Privacy-first JSON & JWT tools that run in your browser
What it does
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.
A professional-grade suite for formatting, validating, anonymizing, and comparing JSON and data files. Secure, browser-based, and local-first.

I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up.
