Kestrel — homepage, docs, design system
Kestrel is a developer-first observability tool. Their homepage had a 74% bounce rate and a docs site that nobody on the product team wanted to touch. We rebuilt both on a shared design system.
.
The brief.
Kestrel wanted the homepage to convert engineers on first read and the docs to actually earn the product. They also needed a shared component library so the product team could ship landing pages without a design bottleneck.
What we did.
Shipped a token-driven component library with Storybook coverage. Rebuilt the homepage as a server-rendered Next.js app that does the heavy lift in markup, not JS.
Rewrote the first three docs pages alongside the product team so the voice travelled from marketing into docs without a seam.
Outcome.
Bounce rate dropped from 74% to 27% on the homepage. Docs sessions went from 1.1 pages to 3.5. The VP of Product now ships landing pages without a design review.
