Type-safe API client generator from OpenAPI

A code generator that turns OpenAPI specs into fully typed, tree-shakeable API clients. Outputs zero-runtime-dependency SDKs in TypeScript and Python.

The work spanned the full lifecycle — from the initial architecture decisions and prototype through to performance tuning, documentation, and the small DX details that make a tool feel finished. The result is something other engineers reach for without thinking about it, which is the highest compliment a tool can get.

Outcome

Adopted across multiple teams and open-sourced under a permissive license. Continues to receive contributions and informs the design of follow-on projects.
