Design System Services that hold one interface together, however many teams ship it.

Three things: design tokens (color, type, spacing) defined once, a component library that exists in code, and the documentation and rules that keep the two in sync. A component library is one of the three rather than a synonym for the whole: the library is the parts, the system is the parts plus the names and the rules that keep them in step. If it only lives in Figma it is a style guide, not a design system, because developers cannot ship a Figma frame. The working test is simple: can a team build an on-brand screen without pinging a designer? When the answer is yes, the system is doing its job.

It pays when several teams, brands, or sites draw from the same UI and inconsistency or duplicated component work is costing real time. It does not pay yet for one small team on a single product: a well-organized component file plus a shared CSS layer gets you most of the benefit for a fraction of the cost, and if that is your situation we will say so on the call rather than sell you a system. In our delivery experience, the tipping point shows up when the same component gets rebuilt slightly differently for the third time.

It depends on scope, so we scope it with you rather than publish a headline price that would be wrong for most projects. Four things drive it: how many surfaces and frameworks the system serves, how much of your current UI has to migrate onto it (usually the largest share of the work), whether accessibility compliance is required, and whether we build once or stay and own it. The audit is deliberately small and produces the estimate for everything after it, so you can stop there. A team that keeps owning the system is team extension, billed monthly per team member.

Not one number, because it is not one deliverable. The audit is the short front end and produces the schedule for everything after it. The build then runs in slices: tokens and a core component set, then the first production screens migrated onto them, then the next slice, so you have working components inside your own product early rather than at the end. What stretches a timeline is almost never the components; it is the number of existing screens to migrate and how many teams have to agree on naming.

Both, and the code side is the point. We build component libraries in React, Vue, or Angular that match the Figma source one to one, with design tokens flowing from design into code and Storybook documentation on top. We do not sell a design system as a Figma library with no code counterpart, for the reason in the comparison above. On one estate of more than 15 warehouse applications the same modules were reused everywhere, so we built universal components in Storybook and integrated them into each application rather than rebuilding per app.

Yes, and we usually should. We start with an audit: token coverage, drift between design files and shipped code, duplicate and orphaned components, accessibility gaps. Then we fix and extend rather than rebuild, unless the audit shows the foundation cannot carry what you need, and we show you the evidence either way. In practice that means working inside what you run: an off-the-shelf UI library you have themed, an older framework version, your CI and release process, and legacy screens nobody will migrate this year. On one training-software platform the whole job was that seam, because the modern components already existed and every legacy implementation had to be mapped onto its equivalent without losing functionality.

Governance, which means an owner, a contribution process, versioning, and a review step for new components. Rot happens when extending a component is harder than forking it, so we set up the tooling and rules that make the right path the easy path. Documentation lives next to the components, and drift between Figma and code gets checked, not assumed. The last piece is honest pruning: components nobody uses get removed, because a bloated system stops being trusted.

Every full-service vendor can offer the tokens, the component library and the governance, this page included, so a comparison only gets useful below the category. Four things are checkable from the outside, and put all four to us as well. A design system is the rare deliverable you can inspect before you sign, so ask to open a Storybook the vendor has shipped, read the props, tab through the states, and check whether accessibility is handled inside the component or in a document beside it. Ask for each review's own URL rather than a star rating: the five quotations under "Our clients say" above each open their own Clutch review. Ask who employs the engineers, because that decides whether the people who named your tokens are reachable when you need the next component; ours are unicrew employees across six countries. And ask what a vendor does not hold. We hold ISO 27001:2022 and ISO 9001:2015, audited by Quay Audit UK, and we do not hold SOC 2, and we would rather say so than let you assume otherwise.
