📚 Collaborative cheatsheets for console commands
What it does
tldr-pages is a community-built library of simplified, example-focused guides for command-line tools — think of it as a 'quick reference card' for the thousands of commands that developers and system administrators use daily, replacing dense technical manuals with short, practical examples. With over 61,000 stars and contributions from 408 people, it has become one of the most popular open-source reference resources in the world.
Why it matters for PMs
The massive adoption of this project signals just how painful developer onboarding and tool discovery remains — there is a clear, proven market demand for making technical workflows more accessible and reducing the time people spend hunting through documentation. For product teams building developer tools or documentation products, this project is a benchmark for what 'good enough to go viral' looks like in the developer productivity space.
