Every time I want to format a JSON blob, decode a JWT, or convert a Unix timestamp, I end up on a different random site — each covered in ads, popups, and "click here to install our extension" banners. Half of them upload my data to their server for no reason.
So this weekend I built DevKits — a single site with 31 developer tools that all run 100% in the browser. No uploads, no accounts, no tracking.
What's in it
Right now, 31 tools across 9 categories:
JSON: formatter, validator, JSONPath tester
