Design Principles

Design Principles is an open source library of design principles and example write ups you can pull into a deck or a design system. The site collects hundreds of documented rules and case examples so you can see how other teams phrased trade offs and how they solved real product problems. It is a quick place to find wording or inspiration when you need a short, argument-ready line about why you chose an approach.

The interface is minimal and the content is pragmatic. You get searchable examples, contributor notes, and links to original sources so you can read the context. The project is maintained by Ben Brignell and accepts community contributions on GitHub, which keeps the collection growing. Because it is open source, you can adapt items to your team’s voice, copy them into pattern libraries, or use them as alignment prompts during crits.
