A lightweight TypeScript library for assertion-based runtime data validation

It would be nice to provide some benchmarks comparing it to Zod, arktype, etc. Comparing it across different runtimes (Node.js, Bun, web browsers, etc.) would be great, too.

Hey, I did some benchmarks if you're interested - benchmarks results are in the README.md.

https://github.com/nimeshnayaju/zod (Fork of Zod's repo which already included benchmarks comparing Zod 4 against Zod 3, so I simply integrated my validation library)

https://github.com/nimeshnayaju/valibot-benchmarks (An unofficial benchmark from another user comparing Valibot against Zod)

Thanks, I appreciate that you added them. :)

They show a lot of potential and promising results. Any guess why Valley is slower for parsing objects with primitive values?
