crux

A small single binary Crystal CLI for everyday DevEx and operations workflows.

Crux is an opinionated but transparent single-binary CLI that consolidates utilities used in the day-to-day. It favors convention over configuration, and tells you exactly what it is doing whenever it touches your system.

See AGENTS.md for the architecture and conventions for adding new commands.

Installation

Homebrew:

brew install lowkeyliesmyth/tap/crux

Or grab a binary for your platform from the releases page.

Usage

crux --help
crux kube
crux kube helmsplit

Every command accepts --help, --debug, and --no-color.

Development

Requires Crystal >= 1.16.3.

shards install
crystal spec
crystal build src/main.cr -o crux
