**APIs profiled:** 2

Kubb Studio is the web IDE for Kubb, the open-source code generator maintained by Kubb Labs (kubb-labs on GitHub). It turns an API specification (OpenAPI 2.0, 3.0 and 3.1) into TypeScript types, API clients, TanStack Query and SWR hooks, Zod schemas, MSW/Faker mocks, Cypress tests and MCP servers, and lets teams review every generated change as a diff before shipping from CI. Generation runs on the customer's own machines via a self-hosted agent (Docker image kubblabs/kubb-agent) and a GitHub Action, with skills for Claude Code, Cursor and Codex; the service is hosted in Europe and is free to start.
