schemabenchmarks.dev is an open source project aiming to provide detailed and transparent comparisons of schema validation libraries.

It measures many aspects of schema libraries, including:

  • Bundle size (and thus download time)
  • Initialisation time
  • Validation time
  • Parse time

Visually, it's heavily inspired by my personal site (which you're currently on), though it uses React and Tanstack Start, whereas this site uses Lit and Greenwood.
