# Why migrate to Valibot?

**[Valibot: The modular and type safe schema library](https://daily.dev/sources/valibot)** · 8 min read · 0 upvotes · 0 comments

## Summary

Valibot is presented as a compelling alternative to schema validation libraries like Zod, offering a small bundle size (1.91 kB gzipped vs Zod v4's 16.57 kB), 16x faster initialization, a clear mental model built around schemas/methods/actions, precise type inference for validation issues, a composable pipeline design, 46 schemas and 118 actions out of the box, and an architecture designed to work well with AI coding agents through predictable, inspectable code structure and llms.txt routes. Migration from Zod is framed as straightforward, with a migration guide and codemod available.
