One button component,
not five slightly different ones
Most teams without a design system end up with a dozen slightly different buttons and three different shades of the same blue, not because anyone decided that, but because nobody had a shared library to pull from. We build the system from your actual product's real screens, tokens, components and usage rules, so the next feature reuses what exists instead of adding one more variant.
What it is
A design system is a set of design tokens, colors, spacing, typography, defined once, and 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, instead of 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 you need it (and when you do not)
It earns its cost once more than a couple of people are building frontend features, or once your brand spans more than one product or surface, a web app and a Mini App, a marketing site and a dashboard, a desktop app alongside both. An AI persona product with a 973-page site needed consistent components across a huge surface area precisely because manual consistency at that scale is not realistic without a shared system underneath it.
It is the wrong tool for a single small product built by one or two developers; the overhead of building and maintaining a formal design system can cost more than the inconsistency it prevents at that scale. We tell teams this directly when a lighter shared stylesheet would do the same job for less.
How we build it
We start with an audit, not a blank slate: screenshotting your existing screens and cataloging every color, spacing value and button variant actually in use, which is usually the first moment a team sees how much drift has happened without anyone deciding it should. Tokens get defined from that audit, consolidating five near-identical blues into one, choosing a type scale that covers the sizes you actually need rather than an arbitrary preset.
The component library is built in code, in whatever framework the product already runs (React, Vue, or plain web components for teams that need framework independence), with each component documented in Storybook or an equivalent: what variants exist, what states it handles (loading, error, disabled), and when to use it versus a different component that looks similar. Accessibility, focus states, contrast, keyboard navigation, gets built into each component by default rather than retrofitted later, since it is far cheaper to get right once in the library than to fix in every screen that used the component before the fix.
Migration happens gradually: we do not propose rebuilding every existing screen on day one, we prioritize the screens that change most often or cause the most visible inconsistency, and let the system prove its value as it rolls out rather than asking for a full rewrite up front.
What to watch
A design system that is too rigid gets forked or ignored the first time a real feature needs something it does not support, so we build in deliberate escape hatches, a way to extend a component without breaking its contract, rather than a system that fights every edge case. Ownership matters: a design system with no clear owner drifts back into inconsistency within a year, so 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 periodically.
Price and timeline
| 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 built; the real ongoing cost is a maintainer’s time reviewing new component requests.

This pairs with micro-frontends for large teams when several teams need to share the same component library across separately deployed apps, and 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, 3 to 6 weeks. A full system covering complex components like data tables and forms, plus a migration of existing screens, runs $6,000 to $12,000.
Do we need a design system if we are a small team?
Maybe not yet. If you have one or two people building one product, a design system's main benefit, consistency across many contributors and surfaces, has less to prove itself against. It becomes worth it once you have more than a couple of frontend developers, or more than one product sharing a brand, since that is where inconsistency actually starts compounding.
Is this a Figma file or real code?
Both, ideally, but the code library is what we insist on, since a Figma file that is not 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, and keep a Figma reference in sync where design and engineering both need it.
What happens to our existing screens?
They do not get rebuilt overnight. We build the library alongside the existing product and migrate screens gradually, prioritizing the ones changed most often, so 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, and the documentation is handed over so your team can extend it without us.
