krane is a command line tool that helps you ship changes to a Kubernetes namespace and understand the result. At Shopify, we use it within our much-beloved, open-source Shipit deployment app. Why not just use the standard Kubectl apply mechanism to deploy?

Gitlab CLI is a Ruby gem and CLI tool that wraps the REST API of GitLab (including self-hosted GitLab instances) to make automation, scripting and integration simpler. It provides a Ruby DSL that abstracts away direct HTTP calls, letting developers interact with GitLab’s API in idiomatic Ruby (creating projects, merge requests, listing users, etc.). In addition to the Ruby library, there is a command-line interface which enables many GitLab operations from the terminal (or scripts) without needing to manually craft API requests. The gem supports customization of endpoint URL, private tokens, proxy and HTTP options, making it suitable for self-managed GitLab instances as well as gitlab.com. It is test-covered and built to be simple to integrate into Ruby projects or CI scripts. Being open-source under a BSD-2-Clause license, it invites reuse in organizational tooling or internal DevOps workflows. Overall, it is a useful tool for teams working with GitLab who want to automate tasks.

puppet-reportprint is a utility for rendering Puppet reports into human-readable output that operators can scan quickly. It takes structured report data and formats it as concise summaries, highlighting changed resources, failures, and metrics that matter during triage. The goal is to help teams move from raw report artifacts to actionable insights without opening a full dashboard or writing ad-hoc parsing scripts. It is designed to fit naturally into existing Puppet workflows, making it easy to drop into pipelines or scheduled jobs that review infrastructure drift. By focusing on clear, consistent formatting, it reduces cognitive load when comparing runs across environments. It’s a pragmatic tool for teams who want faster visibility into configuration management outcomes with minimal overhead.

scrum.rb is a tool for managing scrum projects. It offers a command-line tool, a GUI and a web application for managing and publishing the artifacts of the scrum process.
