Quick reference guides for the tools you use every day

Print-friendly, searchable cheatsheets for developers. Each guide covers the most essential commands and concepts you need when working with these tools. Use the search box on each page to quickly find what you're looking for, or reference them while coding.

All cheatsheets are designed to be printable and optimized for quick lookup in the terminal or browser. For free dev tools, public API docs, and code recipes alongside these references, see the Developer Hub.
