Kubb Studio

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.

Kubb Studio is listed with 2 APIs on the APIs.io network. Tagged areas include Company, Code Generation, OpenAPI, TypeScript, and SDK Generation.

Kubb Studio’s developer surface includes CLI, changelog, sandbox, authentication, getting-started guide, documentation, pricing, and 33 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/kubb-studio/apis.yml: open an issue on github.com/api-evangelist/kubb-studio to ask a question or point us at an artifact you publish.
