A Commander for modern Go CLI interactions
What it does
Cobra is a toolkit that helps software developers build command-line applications — the text-based interfaces that technical users interact with via a terminal or command prompt — quickly and consistently. It powers the command-line tools for some of the biggest platforms in tech, including Kubernetes, GitHub, and Hugo.
Why it matters for PMs
When your engineering team ships a developer-facing product or internal tool, the quality of its command-line interface directly affects adoption and satisfaction among technical users — Cobra is the de facto standard for building those interfaces in Go, meaning teams using it benefit from a proven, widely-trusted foundation. Its widespread adoption across major platforms signals that any product built with it is following industry best practices, reducing risk and speeding up development.
