generated: '2026-08-15' method: searched source: >- npm registry (registry.npmjs.org), PyPI (pypi.org/pypi//json), and the github.com/23andMe organization repository listing via api.github.com note: >- 23andMe publishes NO first-party API client SDK. The Personal Genome API it once wrapped was closed to general third-party developers in September 2018, and no replacement client library has been published to any registry since. No `SDKs` pointer is emitted in apis.yml for this reason — the packages below are real, first-party, currently-maintained open-source libraries, but none of them is a client for a 23andMe API, so crediting them as SDKs would assert an API client surface that does not exist. sdk_count: 0 official_package_count: 3 packages: - language: javascript registry: npm name: styledot url: https://www.npmjs.com/package/styledot install: npm install styledot official: true api_client: false kind: design-system version: 3.15.0 published: '2026-05-06' repository: https://github.com/23andme-private/style note: >- 23andMe Design System. First-party — the npm maintainer list includes the `23andme` org account alongside named 23andMe engineers. The backing repository (23andme-private/style) is private, so the component surface is not publicly documented; this is an internal design system published to npm, not a public embeddable component library, and no Components artifact is emitted for it. - language: javascript registry: npm name: styledot-docs url: https://www.npmjs.com/package/styledot-docs install: npm install styledot-docs official: true api_client: false kind: design-system-docs version: 1.0.7 published: '2021-12-03' repository: https://github.com/23andme-private/style note: >- 23andMe styleguide docs. Sole npm maintainer is the `23andme` org account. Last published 2021-12-03 — nearly five years stale against styledot 3.15.0 (2026-05-06), so the published docs no longer track the design system itself. - language: python registry: pypi name: yamale url: https://pypi.org/project/yamale/ install: pip install yamale official: true api_client: false kind: developer-tool version: 6.1.0 published: '2025-11-20' repository: https://github.com/23andMe/Yamale note: >- A schema and validator for YAML. 23andMe's most widely adopted open-source project (771 stars) and the org's most recently active repository (pushed 2026-08-13). General-purpose tooling — unrelated to any 23andMe API. unmaintained_first_party: - language: python registry: pypi name: seqseek url: https://pypi.org/project/seqseek/ official: true api_client: false kind: bioinformatics-library version: 0.4.2 published: '2021-10-01' author: 23andMe Engineering repository: https://github.com/23andMe/seqseek note: Human reference genome sequence access.

Actively maintained on GitHub but absent from PyPI — pypi.org/pypi/yhaplo/json returns 404, so there is no registry metadata to read a version or release date from. - name: phasedibd repository: https://github.com/23andMe/phasedibd registry: null version: null published: null official: true api_client: false note: >- Identity-by-descent inference (47 stars, pushed 2026-02-23). Absent from PyPI; installed from source only, so consumers cannot pin a published version. - name: bonsaitree repository: https://github.com/23andMe/bonsaitree registry: null version: null published: null official: true api_client: false note: Pedigree reconstruction.
