xsschema

xsschema is an extra-small, Standard Schema-based alternative to typeschema, providing a unified schema validation layer for multiple validation libraries (Zod, ArkType, Effect, Valibot) with JSON Schema generation. Current version is 0.5.0-beta.5 (pre-release). It has no release cadence yet. Key differentiators: standardized adapter interface (Standard Schema), lightweight footprint, and seamless integration with the xsai ecosystem. Ships TypeScript types.
