Philosophy

Built for the
way you work

Developer tools should adapt to your stack — not the other way around.

Core + Adapters

Business logic is framework-agnostic. Adapters connect to your stack. Switch from Next.js to Remix without rewriting.

Type-safe by default

Full TypeScript coverage with Standard Schema. Validate at runtime with Zod, Valibot, or ArkType — your choice.

Tested extensively

Comprehensive test coverage ensures reliability. Not toy examples — real solutions built for production.
