### What we like

Terminal UI for exploring JSON files, streams, or piping JSON through pre-processing. Interactive mode for searching JSON and visually expanding the structure. Has Vim compatible keybindings. Includes built-in functions e.g. for fetching data, sorting, counting, etc. Open source & available as a single (Go) binary.

### Tradeoffs

Missing some Linux packages e.g. Debian, Yum, etc.
