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.

Created in collaboration with Open Circle, an open source organisation led by Fabian Hiller.
