The contract layer between design and development.

What is Parlance

One platform for design-development contracts.

Parlance is a platform for creating, managing, and verifying component contracts between designers and developers. Every contract defines exactly what a component is — its props, states, variants, accessibility requirements, and design tokens — validated against W3C standards.

Where design systems document intent, Parlance enforces it. Contracts are precise, verifiable agreements that either pass or fail. There is no ambiguity, no interpretation, no “close enough.”

The glossary translates design tokens to 10+ frameworks automatically — Tailwind, CSS variables, SwiftUI, UIKit, Jetpack Compose, and more — so everyone speaks the same language.

The problem

Design handoff is broken.

Designers design one thing. Developers build another. QA catches the mismatch weeks later. Design tokens get lost in translation. Accessibility requirements get forgotten. Component specs live in Figma comments that no one reads.

The design system is “maintained” in a Notion document that's three months out of date. Every team we've spoken to has this problem. Parlance exists to solve it.

How it works

Define. Validate. Reconcile.

The company

A product by the pace.

Parlance is built by the pace — a design and technology studio focused on building tools that bridge the gap between design intent and technical implementation.

the pace builds products at the intersection of design systems, accessibility, and developer tooling — for product teams who care about the gap between what was designed and what gets shipped.
