An intelligent design system, and the engineers behind it
Ship faster because the system does the checking.
bun add @fusion.dev/helixCustom elements, built on Lit. Works in React, Vue, Svelte, or no framework at all.
An interface is cheap to start and expensive to keep
The first screen is a morning. The second brand, the framework migration and the accessibility audit are the rest of the year, and none of them is visible on the day you start. Helix is built for that year, not the morning.
Derived, not picked
It survives the second brand
- One brand color in, a full palette out
- The engine refuses a palette it cannot make readable
Standards, not bindings
It survives the framework
- Custom elements, so they upgrade in any framework or none
- Typed for React, Vue and Svelte from one manifest
Measured, not claimed
It survives the audit
- Contrast is measured on every release, not asserted once
- Twelve generators judge the tree and fail it when it drifts
Readable, not scraped
It survives the agent
- Every tag, property and event as one manifest, at a URL
- Every page answers as Markdown, every component family as JSON
Derived, not picked
What happens between the color and the page
The first of those three, drawn out. One value goes in, the whole token layer comes out, and every pair it produces is measured against the ground it lands on before any of it reaches a page.
Standards, not bindings
Every control here is the real one
Not a screenshot and not a video. These are custom elements from the package, upgrading in your browser on the page you are already reading.

How it arrives
Three ways to get Helix into your product
Every price is published, because an offer you cannot compare is not an offer.
AI capability audit
Design system sprint
Conversational build
The engagement
How the work goes
Helix is the system. This is what it is like to have the people who built it working in your codebase.
The system already exists
It is faster because of that
You keep all of it
We tell you what is not done
Insights
The arguments, written down
Design, engineering and business decisions, with the reasoning kept in.
