JSONaire

Fast JSON viewer for big files

JSONaire is a JSON viewer for macOS that opens the files other viewers can't. Drop in a document that makes your current tool freeze, beachball, or give up. JSONaire parses around 430 MB of JSON per second, so a hundred-megabyte API dump is on screen in well under a second, and multi-gigabyte documents take seconds rather than minutes.

Worldwide Release Date: August 26, 2026
