Introducing Parlance: the contract layer for design systems

After years of watching the same problems repeat — tokens lost in handoff, accessibility flagged too late, component specs scattered across six tools — I built the thing I wish I'd had.

Parlance is the contract layer between design and development. It lets you define component contracts — props, tokens, accessibility requirements, usage rules — in a structured, versionable format. Then it enforces them.

How it works

Every component gets a contract. That contract specifies what the component accepts, which tokens it uses, and what accessibility criteria it must meet. Parlance validates these contracts against W3C specifications automatically.

Integrations

Parlance connects to the tools teams already use. Figma for design. VS Code and Xcode for development. GitHub Actions for CI. The API is open for custom workflows.

What's next

Parlance is live at parlance.business. I'm actively building new features — including richer audit reports, team collaboration, and deeper Figma integration.

If you're tired of the handoff gap, give it a look.
