Like many developers, I was frustrated with JSON tools that were full of ads, slow to load, and worst of all — silently sending my API data to their backend servers.
So I built BestOfTool.com — a unified suite of 15+ JSON tools (formatter, validator, minifier, compare, CSV/XML/YAML converter) that run 100% inside your browser. Your data never leaves your machine.
Currently available at bestoftool.com — completely free for core tools. Would love feedback from this community!
