One button component,
not five slightly different ones
Most teams without a design system end up with a dozen slightly different buttons and three shades of the same blue. Nobody decided that on purpose. They just never had one shared library to pull from. We build the system from your actual product: its real screens, tokens, components and usage rules. The next feature reuses what exists instead of adding one more variant.
What a design system actually is
A design system is a set of design tokens, colors, spacing, typography, all defined once. It also includes a component library (buttons, inputs, cards, modals) built from those tokens and documented with its variants and states. The code version is what actually enforces consistency. A developer reaching for a button component gets the one correct button. They’re not copying an old one and tweaking it slightly, which is how most products end up with a dozen near-identical variants nobody can tell apart.
When it earns its cost (and when it doesn’t)
It earns its cost once more than a couple of people build frontend features, or once your brand spans more than one product or surface. Think a web app and a Mini App, a marketing site and a dashboard, maybe a desktop app too. One of our clients runs a large content product that generates 973 SEO pages from a single core template. Consistent components across a surface that size are not realistic without a shared system underneath them.
It’s the wrong tool for a single small product built by one or two developers. Building and maintaining a formal design system there can cost more than the inconsistency it prevents. We tell teams this directly when a lighter shared stylesheet would do the same job for less.
How we actually build it
We start with an audit, not a blank slate. We screenshot your existing screens and catalog every color, spacing value and button variant actually in use. This is usually the first moment a team sees how much drift has happened without anyone deciding it should. Tokens get defined from that audit: five near-identical blues become one, and the type scale covers the sizes you actually need instead of some arbitrary preset.
The component library gets built in code, in whatever framework the product already runs, React, Vue, or plain web components where a team needs framework independence. Each component is documented in Storybook or an equivalent. That covers what variants exist, what states it handles (loading, error, disabled), and when to use it instead of a similar-looking component. Accessibility, focus states, contrast, keyboard navigation, gets built into each component by default rather than fixed later. It’s far cheaper to get right once in the library than to patch every screen that used the old version.
Migration happens gradually. We don’t propose rebuilding every existing screen on day one. We prioritize the screens that change most often or cause the most visible inconsistency. The system proves its value as it rolls out, instead of asking for a full rewrite up front.
Where design systems tend to rot
A design system that’s too rigid gets forked or ignored the first time a real feature needs something it doesn’t support. So we build in deliberate escape hatches, a way to extend a component without breaking its contract, instead of a system that fights every edge case.
Ownership matters too. A design system with no clear owner drifts back into inconsistency within a year. We recommend naming one person, or a small group, responsible for approving new components, even on a small team. And a system built once and never revisited ages out as the product grows. We hand over the audit process itself, not just the output, so your team can re-run it on its own.
What it costs and how long it takes
| Option | Price | What it covers | Timeline |
|---|---|---|---|
| Tokens and core components | from $3,500 | Audit, tokens, buttons/inputs/cards/typography, documentation | 3 to 4 weeks |
| Full system with migration | from $7,000 | Everything above plus complex components and a phased migration plan | 5 to 8 weeks |
Running cost is close to zero once it’s built. The real ongoing cost is a maintainer’s time reviewing new component requests.
What this pairs with
This pairs with micro-frontends for large teams when several teams need to share one component library across separately deployed apps. It also pairs with accessibility-compliant web app, since accessibility is easiest to fix at the component level. See the development service page for our full build process. For real examples, see the AI persona business’s large-scale site and the multi-vendor marketplace platform.

FAQ
How much does a design system cost?
From $3,500 for tokens and a core component set (buttons, inputs, cards, typography) built from your existing product. That's 3 to 6 weeks. A full system covering complex components like data tables and forms, plus migrating existing screens, runs $6,000 to $12,000.
Do we need a design system if we are a small team?
Maybe not yet. If one or two people build one product, a design system's main benefit, consistency across many contributors and surfaces, has less to prove itself against. It starts paying off once you have more than a couple of frontend developers, or more than one product sharing a brand. That's when inconsistency actually starts compounding.
Is this a Figma file or real code?
Both, ideally, but the code library is what we insist on. A Figma file that isn't wired to what developers actually import drifts out of date within a quarter. We build the component library in code first, in whatever framework your product already uses. We keep a Figma reference in sync wherever design and engineering both need it.
What happens to our existing screens?
They don't get rebuilt overnight. We build the library alongside the existing product and migrate screens gradually, starting with the ones that change most often. The system proves its value before you commit to a full rewrite.
Who owns it?
You. The component library lives in your own repository, usually as a shared package your other repositories import. The documentation is handed over so your team can extend it without us.
