Four surfaces. One contract. Not four disconnected tools.
Most teams check their design system with a different tool for each surface — and none of them agree. Parlance holds design, code, live and native to a single contract, with severity triage and accessibility standards built in.
Every surface is checked by a tool that can’t see the others.
A screenshot diff watches the rendered component. A token sync pushes variables into code. A scanner audits one live page. Docs describe how it should look. Each is useful, and none of them knows what the others expect — so design and code quietly drift apart.
Not a screenshot diff. Not a token sync. Not a scanner.
Each of those solves one slice of the problem. Parlance holds the whole system — design, code, live and native — to a single contract, with severity triage and accessibility standards built in.
Screenshot diffs
They flag when a rendered component changes shape.
Parlance checks the component against the contract it must meet — across design, code, live and native at once.
Token sync
It pushes design tokens from one place into your code.
Parlance holds every surface to those tokens and catches the moment one drifts off them.
Accessibility scanners
They scan a single page for issues on demand.
Parlance makes each standard a clause every surface is measured against, continuously.
Design-system docs
They describe how a component is supposed to look.
Parlance enforces that description everywhere your product actually ships.
One tool, or the whole set.
Neighbouring categories each cover a slice — credited fairly below. Parlance is the one that holds every surface to the same contract.
| Capability | Screenshot diffs | Token sync | A11y scanners | DS docs | Parlance |
|---|---|---|---|---|---|
| Audits design files | No | No | No | No | Yes |
| Audits code | Partial | Partial | Partial | No | Yes |
| Audits live URLs | Yes | No | Yes | No | Yes |
| Audits native apps | Partial | No | No | No | Yes |
| Enforces design tokens | No | Yes | No | No | Yes |
| Severity triage | No | No | Yes | No | Yes |
| Maps to accessibility standards | No | No | Yes | No | Yes |
| One shared contract, every surface | No | No | No | No | Yes |
Categories describe kinds of tool, not specific products, and are credited wherever they genuinely apply.
Teams shipping one design system in more than one place.
If your product lives across design files, a codebase, a live site and native apps — and all of them are meant to tell the same story — Parlance is the layer that keeps them honest to each other, not just to themselves.
