Summary

Terrazzo is a set of open-source tools for creating and managing design systems, with token workflows centered on a command-line interface. The CLI reads design-token JSON following DTCG and generates code for outputs including CSS, Sass, and JavaScript or TypeScript; it can run manually or within continuous integration. Lint rules can check token formatting, naming consistency, duplicate values, color gamut, and accessibility criteria such as minimum contrast and font size. Documented integrations cover CSS, JavaScript, JSON or native output, Sass, Tailwind, and Vanilla Extract. Its Tailwind plugin creates a Tailwind v4 theme from DTCG tokens. The CLI can export Figma Variables and Styles to resolver JSON, with a Figma account and authentication token required for import. Configuration accepts JSON, JSONC, and YAML. The Swift plugin creates Swift asset catalogs but is experimental. Terrazzo began as Cobalt in 2021, and its MIT-licensed tools are free to use. Design Lab is listed as coming soon.

Who it is for

Terrazzo suits design-system teams that manage design tokens and want generated code, linting, and documented integrations. It may fit teams working with DTCG tokens, Figma, or one of the supported starting systems.

What is good
