Catch design drift
before it ships.

Design systems drift over time. Buoy watches every PR for hardcoded colors, token violations, and rogue components. โ›ต

Or scan any public GitHub repository for design drift, free, in about a minute.

๐Ÿ’ง Design systems leak.

Hardcoded values creep in. Drift compounds.

What AI generates Card.tsx
const Card = () => (
  <div style={{
    background: "#ffffff",
    padding: "16px",
    borderRadius: "8px",
    boxShadow: "0 2px 4px rgba..."
  }}>
    {children}
  </div>
)
What you want Card.tsx
import { Card } from "@/components"

const MyCard = () => (
  <Card variant="elevated">
    {children}
  </Card>
)


๐Ÿ›Ÿ Buoy plugs the holes.

What Buoy catches:
โš 
Hardcoded colors
#ffffff โ†’ var(--bg)
โš 
Magic numbers
16px โ†’ var(--space-4)
โš 
Duplicate components
Use <Card> instead
