What slows teams down

Weeks rebuilding primitives that still don’t match Figma.
Brand drift across web, mobile, and components.
Auth rabbit hole: DIY is slow, hosted means lock-in & surprise fees.
Design → Dev mismatch: tokens & states never line up 1:1.

How Etesie flips it

Theme-aware primitives that mirror production UI.
Real design-dev parity: Editor → Figma → code stays in sync.
Auth you own: no per-user/org pricing. Self-host your data.

How Etesie works

1 — Create your Theme

Use the Theme Editor (free) to define colors, typography, surfaces—even multiple brands. Explore community themes and push tokens to Figma & GitHub.

2 — Design with Parity

Use the Figma Design System Kit (Primitives) and Auth UI Kit. States map 1:1 to code with dark/light & brand variants.

3 — Ship Auth you Own

Add Auth to SvelteKit or Nextjs. Built on Better Auth + Convex. Self-host, no per-user pricing, full code ownership.

“...the Figma is very well put together and the most robust that I could find out of all the UI kits so our company chose to go with Skeleton 🙂”
