## What it is
jql (pronounced 'jackal') is a fast, lightweight JSON Query Language CLI tool written in Rust for selecting and manipulating JSON data. It supports array indexes, ranges, lenses, and group separators, and is available via many package managers.

## Use cases
- query and filter  from the command line
- extract specific fields from a  file
- slice and reorder  arrays
- pipe  between shell commands
- alternative to jq for  manipulation

## When to choose
- you want a fast, lightweight jq alternative written in Rust
- you need meaningful error messages when querying JSON
- you want a tool installable via brew, cargo, apk, dnf, and more

## When to avoid
- you need jq's mature ecosystem and scripting features
- you need to query non-JSON formats like YAML or CSV
- you need complex transformations beyond selection

## Facets
- artifact type: cli-tool
- maturity: active
- function: cli, parser, developer-tools
- domain: developer-tools, files
- platform: windows, cli, cross-platform
- tags: -query-language, -processing, jq-alternative, rust, command-line, linux, macos
