Enterprise Design Systems for
Speed, Consistency, Governance.

Move beyond “UI kits.” We build token-driven design systems and component libraries that scale across products—backed by accessibility QA, documentation, and versioned governance for predictable evolution.

Beyond the UI Kit.
Systems, Not Screens.

Most “design systems” fail because they stop at components. Without tokens, accessibility gates, and governance, the UI drifts and teams fork patterns. We build design systems that survive Day 2.

The Design System Failure Pattern

What most “build teams” ship:

  • No Token Architecture

    Spacing, color, and typography become hard-coded and drift fast.

  • Component Sprawl

    Teams fork variants; maintenance cost explodes with every release.

  • Zero Governance

    No contribution model, no versioning discipline, no adoption feedback loop.

The Coretus Design System Standard

Production-grade UI infrastructure:

  • Token-Driven Foundations

    Design tokens for theming, density, typography, color, and motion across platforms.

  • Composable Component Architecture

    Accessible primitives + consistent patterns built for long-term maintainability.

  • Governance + QA Gates

    Contribution model, versioned releases, and automated checks to prevent regressions.

Less Drift. More Shared UI Truth.

Frequently Asked
System Questions.

Service Identity
Enterprise Design Systems

Do we need tokens before components?

Yes. Tokens prevent drift across products and themes—components become stable consumers of shared foundations.

How do you prevent component sprawl?

We define composable primitives, constrain variants, document usage, and enforce gates through governance.

Accessibility coverage included?

Yes. We build keyboard and ARIA patterns, contrast rules, and regression checks aligned to WCAG principles.

Figma ↔ code workflow support?

Yes. We set library structure, token sync strategy, and guardrails so design and code stay aligned.

How do releases and governance work?

Versioned releases, changelogs, RFCs, and migration playbooks—so evolution is predictable.

Design System Audit?

We can deliver a rapid audit to map token needs, component sprawl, a11y gaps, and governance requirements.
