Design token set
Named values for color, spacing, type, radius, and motion, structured to be consumed directly by code, not manually copied.
Infrastructure
Design systems built to be implemented in code, not admired in a file
A design file full of components nobody built is not a design system. We build tokens and components that ship, with documentation and a handoff model that keeps design and engineering on the same page after launch.
A lot of what gets called a design system is a well-organized component library in a design tool with no coded equivalent. It looks complete right up until an engineer has to build a new screen and discovers the spacing values were never actually defined, just eyeballed to look consistent. The system falls apart at the exact moment it needed to hold up.
We build design systems as a shared contract between design and engineering, not a design artifact that engineering interprets from screenshots. That means starting with tokens, the actual values for color, spacing, type scale, and elevation, defined once and consumed by both the design file and the codebase. When a token changes, it changes everywhere, instead of triggering a manual audit of every screen.
Components are built the same way: designed and specified with real states, including error, loading, disabled, and empty states, then built in code to match, not approximated afterward. We are direct about scope here. A design system that only covers the happy path is not finished, it is a demo.
The documentation is what makes the system survive contact with a team that is not us. Every component gets usage guidance, do and don't examples, and accessibility notes, so a new engineer or designer can use it correctly without pulling someone into a meeting to explain it.
What it is
What the system actually contains
Tokens first, then components, then the documentation that keeps them from drifting apart over time.
Design tokens are the foundation: named values for color, spacing, typography, radius, shadow, and motion, structured so they can be consumed directly by code rather than copied by hand from a design file. This is the layer most teams skip, and it is the layer that causes the most drift once a system is in real use.
Component specifications cover every meaningful state of a component, not just its default appearance. A button needs a defined disabled state and a loading state before it ships, not after a support ticket points out it is missing one. We document these states alongside the visual spec so nothing gets lost in translation to code.
The coded component library is where the system becomes real. We build components using the front-end stack your product already runs on, so there is one source of truth instead of a design version and a separate, slightly different coded version maintained independently.
Governance is the part most systems never plan for: who can propose a new component, how changes get reviewed, and how the system version gets communicated to teams consuming it. Without this, even a well-built system degrades within a couple of product cycles as teams quietly diverge from it under deadline pressure.
Fit
Who this is for, and who it is not for
We would rather say no early than sell a program that cannot work.
Right fit
- Your product has grown past the point where a shared component library in the design tool alone is enough.
- Design and engineering are visibly drifting, with the coded product no longer matching the design files.
- You are building a new product from the ground up and want to avoid accumulating inconsistency from day one.
Not the right fit
- You have a single small product with no near-term plans to add more screens or a second product surface.
- You want a system built purely as design-file components with no coded implementation. That is a partial solution and we say so.
- You need a brand identity established first. See brand identity, since a design system without a settled brand foundation gets rebuilt twice.
Deliverables
What you receive
A system that lives in your codebase, not just a design tool file.
Component specifications
Every component defined with its default, hover, disabled, loading, error, and empty states, not just the happy path.
Coded component library
Components built in your product's actual front-end stack, so design and engineering share one source of truth.
Usage documentation
Do and don't guidance, accessibility notes, and real usage examples for every component in the system.
Contribution and governance model
A defined process for proposing, reviewing, and versioning changes so the system does not quietly drift after launch.
Accessibility and QA pass
Components checked for contrast, keyboard navigation, and screen reader behavior before they are marked as ready to use.
How we run it
How a design system gets built
Tokens before components, components before governance.
Step 1: Audit existing patterns
We inventory what already exists across the product, flagging where the same pattern has quietly diverged into three versions.
Step 2: Define tokens
Color, spacing, type, and motion values get named and structured for consumption by both design files and code.
Step 3: Design and spec components
Components are designed with every meaningful state defined, not just the default appearance shown in a mockup.
Step 4: Build in code
Components are implemented in your actual front-end stack, verified against the design spec, and checked for accessibility.
Step 5: Document and hand off
Usage documentation and a governance model ship alongside the library, so the system survives beyond the initial build.
What is a design system, in practical terms?
A shared set of design tokens, coded components, and documentation that design and engineering both consume from the same source, so a product stays visually and behaviorally consistent as more people build on it.
Why do design systems fail after launch?
Most fail because they exist only as design-file components with no coded equivalent and no governance model, so engineering approximates them under deadline pressure and the two versions quietly drift apart within a few product cycles.
Where this connects
Where design systems connect
A design system sits between the brand foundation and the product it gets built into.
A design system should express an already-settled visual language, which is why it usually follows brand identity rather than being built in parallel with it.
Once components exist, they get applied to actual product screens through UI design which uses the system rather than reinventing patterns per screen.
Systems that include motion tokens or interaction patterns coordinate directly with motion graphics so animated transitions stay consistent across the product.
The most common place a coded component library actually ships is inside a SaaS frontend since that is where the same components get reused across dozens of screens and the drift problem is most expensive to leave unfixed.
