I compared JSON Formatter Pro and ReqBin for working with JSON in Chrome

Full disclosure: I built JSON Formatter Pro as part of Zovo, a collection of Chrome extensions I maintain. Take my perspective accordingly. That said, I will be as honest here as I would want someone to be with me. JSON Formatter Pro wins this comparison for pure JSON formatting tasks, while ReqBin serves better for comprehensive API testing workflows. After testing both extensions extensively, JSON Formatter Pro delivers superior performance with a 4.8/5 rating versus ReqBin's 3.8/5, plus more recent updates and dedicated JSON optimization. The debate really comes down to whether you need specialized JSON tools or broader HTTP testing capabilities.
