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
