[ 01 / How it works ]

A domain in. A themed interface out.

Three calls end to end, and the middle one is ours. Nothing to collect from the customer, nothing to hand build per tenant.

Resolve

Work out whose brand to load

A subdomain, a work email domain, or a tenant record you already store. All you need is a domain.

const domain =
  tenant.domain ??
  req.hostname.split('.')[0];

Fetch

Ask for the design system

One call returns colours by role, the type scale, corner radius, button styling and contrast ratios, read from a real browser.

const style = await hf.styleguide({
  domain,
});

Apply

Set the variables and move on

Write the values onto the root element. Every component that reads your tokens restyles itself.

root.style.setProperty(
  '--accent',
  style.colors.accent,
);

[ 02 / The demo ]

Change the domain. Everything else follows.

Switch tenant below and watch the logo, name, industry, palette, typeface, corner radius and light or dark mode all move together. Four real captures, one set of markup.

Same markup, four tenants. The logo, name, tagline, palette, typeface, corner radius, button shape, switch colour and light or dark mode all arrive from the domain. Nothing in the panel is written per brand, and the bar chart is coloured from that company's own ranked palette rather than from a scale we picked.
