## What it is
jwt-cli is a fast command-line tool written in Rust for decoding and encoding JSON Web Tokens (JWTs). It supports custom headers, arbitrary JSON claim bodies, and any signing secret, with prebuilt binaries for Linux, macOS, and Windows.

## Use cases
- decode a jwt token from the command line
- encode a jwt with custom claims and secret
- debug jwt headers and payloads in a terminal
- generate signed json web tokens for testing apis
- inspect jwt claims quickly without a web tool

## When to choose
- you need fast, scriptable JWT encode/decode in shell scripts or CI
- you want custom claim bodies and headers beyond typical JWT tools
- you need a portable cross-platform binary with no runtime dependencies

## When to avoid
- you need a GUI or web-based JWT debugger
- you need full JWT library features inside an application rather than a CLI
- you're on a 32-bit or unsupported platform without a Rust toolchain

## Facets
- artifact type: cli-tool
- maturity: active
- function: cli, security, serialization, json
- domain: developer-tools, security, apis
