## What it is
fx is a terminal JSON viewer and processor written in Go, offering an interactive TUI for exploring JSON and JavaScript-expression-based transformation in non-interactive mode. It also supports YAML and TOML, streaming JSON, and ships as a single self-contained binary.

## Use cases
- explore large json files in the terminal
- transform json with javascript expressions from the command line
- view curl api responses interactively
- process line-delimited json streams
- convert or inspect yaml and toml files
- extract fields from json in shell scripts

## When to choose
- you want a jq alternative with JavaScript syntax instead of a custom DSL
- you need an interactive TUI to navigate and search large JSON documents
- you need a single static binary with no runtime dependencies
- you work with streaming or line-delimited JSON

## When to avoid
- you need jq's mature ecosystem or existing jq scripts
- you need programmatic JSON manipulation inside an application rather than a CLI
- you rely on the interactive viewer on Windows, where only the Go-installed non-interactive mode is supported
