NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar.

Valibot is a schema validation library in TypeScript. Like other popular TypeScript validation libraries such as Zod and Ajv, it provides type inference, but its modular design sets it apart. This architecture allows bundlers to perform effective tree shaking and code splitting, including only the validation functions actually used. Valibot can reduce the bundle size by up to 95% compared to Zod in optimal scenarios. It’s an appealing choice for schema validation in environments where bundle size is critical, such as client-side validation or serverless functions.
