Valibot is a modular, type-safe schema library for TypeScript that validates and parses unknown structural data at runtime while inferring static types. Its modular API design keeps bundle size extremely small, starting at under 700 bytes.
Use cases
- validate api request bodies at runtime
- parse and validate form input in a react app
- infer typescript types from a schema
- validate json config files
- validate unknown data from external sources
- small bundle size schema validation for frontend
When to choose
- you need runtime validation with static type inference in TypeScript
- bundle size matters, e.g. for frontend or edge deployments
- you want a modular, tree-shakeable alternative to Zod
When to avoid
- your project is plain JavaScript without TypeScript
- you need a schema library with a very large ecosystem of prebuilt plugins
- you only need compile-time type checking with no runtime validation
