Design systems streamline development, communication, and consistency – but often rely on dedicated teams and extended budgets. We wanted a tool that helps create and maintain living style guides & pattern libraries in an agile process, and on a budget. Herman helps you keep your development process simple – and your UX consistent – as you scale over time.

OddBird’s Accoutrement tools help keep design tokens meaningful to both humans and machines – opening the door for automation, while improving readability. These tools also integrate with Herman, our automated pattern-library generator.

True is the only full-featured unit-testing framework designed specifically for the Sass language. Write your tests in Sass, compile them with Sass, and then (optionally) pass the results to a Javascript test-runner for command-line control and reporting.
