A serene ark, sailing to runtime

ArkType

TypeScript's 1:1 validator, optimized from editor to runtime.

What awaits

Unparalleled DX

Type syntax you already know with safety unlike anything you’ve ever seen

Faster. Everywhere.

100x faster than Zod with editor performance that will remind you how autocomplete is supposed to feel

Clear and concise

Schemas are half as long and twice as readable with hovers that tell you just what really matters

Better errors

Deeply customizable and composable messages with great defaults

Deeply introspectable

ArkType uses set theory to understand and expose the relationships between your types at runtime the way TypeScript does at compile time

Smarter by default

Every schema you define is internally optimized to provide the clearest, fastest validation possible
