/02

Feels like you’ve used it before.

Already know Zod? You already know VLD. Familiar schemas, familiar methods, one new import.

Make the switch
/03

Speaks your users’ language.

Helpful errors in 27+ languages, with lazy loading. Because clarity shouldn’t get lost in translation.

Meet the locales

Life’s complicated. Your validation doesn’t have to be.

LESS GUESSWORK. MORE BUILDING.

See certainty
in action.

A familiar API. An unfamiliar amount of speed.
Give your data a little reality check.

REAL VLD. RIGHT IN YOUR BROWSER.

Your schema is your type. Always in sync.

No setup. No server. Just your data.
FAST IS A FEATURE.

Your app has
places to be.

Validation shouldn’t be the thing slowing it down.
Less waiting. Less memory. More room to build.
