Thank you, this is quite helpful. Will take a detailed look very soon!

How do you know you're tool is more performant?

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 suggested in another comment comparing Valibot against Zod)

Hey, thanks for the link! I was able to add the library to the benchmark quite easily. Here's the fork if you're interested:

I have included the results I obtained from running the benchmark in the README.md. I'd love for you to also take a look at the changed code to see if I may have missed something with the integration. Curious to hear your feedback too!

Nicely done, and thanks for following up!
