Compared on batch processing, jq and JSONPath querying, JSON diff and compare, and schema validation, the entries also show available platforms, free-plan status, and paid-from pricing. jsonfmt.dev starts the ranking, followed by JSONZen and BracketView; JSONLint and JSON Crack are also among the first entries.
