history

Project history and usage

Cassowary is a Go HTTP/S load-testing CLI for developers, testers, and sysadmins. Its README positions it as a cross-platform tool inspired by k6, ab, and httpstat.

Project history

The official README emphasizes a single binary, Go implementation, and importable module design. The project packages both a CLI and a library surface, with release binaries and a documented Go module path.

Adoption history

Adoption is niche and developer-tool focused. The README documents installation through GitHub releases, Homebrew on macOS, Docker, Arch/Manjaro AUR, Nix/NixOS, and RPM-building support, and it advertises an Awesome Go mention.

Homebrew analytics show 119 installs in the last 365 days in the formula API.

How it is used

Typical use is `cassowary run` with a URL, concurrency, and request count. The README documents standard load tests, file slurp mode, JSON/CSV metrics export, Prometheus Pushgateway export, CloudWatch metrics, histograms, boxplots, POST data, durations, custom headers, x509 authentication, and distributed load testing.

Why package nerds care

Cassowary is package-nerd interesting as a compact Go alternative to older HTTP benchmark tools: it offers one static-ish cross-platform binary, modern metrics outputs, and package-manager distribution without a service runtime.

Timeline

  • v0.10.0 and earlier: File slurp mode used its own command, according to the README note.
  • 2026: Homebrew formula packages v0.19.0 from the official GitHub release archive.

Related projects

  • The README names k6, ab, and httpstat as inspirations.
  • Prometheus Pushgateway and AWS CloudWatch are documented metrics export targets.
