# Porsche > Porsche AG is a German luxury sports-car manufacturer and a Volkswagen Group brand. It > operates a developer estate, but almost none of it is public: the Porsche ID Developer > Portal states plainly that Porsche offers no public APIs, and both it and the Porsche > Developer Hub are restricted to Porsche AG and approved Porsche Partner Companies. The > one substantial public developer surface is the Porsche Design System — an open web > component library with its own documentation site, npm packages and CDN. Generated by the API Evangelist enrichment pipeline on 2026-08-27 from probed Porsche surfaces. Porsche does not publish an llms.txt of its own; /llms.txt returns 404 on porsche.com, developer.porsche.com, developerhub.porsche.io, designsystem.porsche.com, opensource.porsche.com and identity.porsche.com. ## What is and is not callable - There is **no public Porsche API**. No OpenAPI, Swagger, GraphQL SDL, AsyncAPI, WSDL or Protobuf contract is published on any anonymously reachable Porsche host. - API access requires becoming a **Porsche Partner Company** through the VW Group Supply Portal, then being onboarded by Porsche's integration team. - There is **no A2A agent card** and **no publicly reachable MCP endpoint**. ## Developer surfaces - [Porsche ID Developer Portal](https://developer.porsche.com/): landing page, terms, privacy policy and FAQ are public; everything else requires partner access. - [Porsche ID API portal (gated)](https://portal.developer.porsche.com): redirects to a Microsoft Entra ID login. - [Porsche Developer Hub](https://developerhub.porsche.io/): APIs plus "Streamzilla" real-time streaming. Public landing page only; /docs redirects to a sign-in offering Entra ID or KUMS MFA. - [Developer Portal FAQ](https://developer.porsche.com/faq): the authoritative statement of the access policy. - Integration contact: touchpoint-integration-porsche-id@porsche.de - [VW Group Supply Portal](https://www.vwgroupsupply.com/one-kbp-pub/en/kbp_public/homepage/homepage.html): where partner status is applied for. ## Identity (public and machine-readable) - [Porsche ID OpenID Connect discovery](https://identity.porsche.com/.well-known/openid-configuration): issuer https://identity.porsche.com/. Supports authorization_code, client_credentials, refresh_token, device_code, token-exchange and jwt-bearer grants; PKCE S256; DPoP (ES256); CIBA backchannel authentication; dynamic client registration; back-channel logout. Credentials are still partner-gated. - [Porsche CIAM discovery](https://login.porsche.com/.well-known/openid-configuration): a thin second document; authorization delegates back to identity.porsche.com. ## Porsche Design System (the public surface) - [Documentation](https://designsystem.porsche.com/v4/) - [Changelog](https://designsystem.porsche.com/v4/news/changelog) - [Repository](https://github.com/porsche-design-system/porsche-design-system) - [Agent context (AGENTS.md)](https://raw.githubusercontent.com/porsche-design-system/porsche-design-system/main/AGENTS.md) - [Security policy](https://github.com/porsche-design-system/porsche-design-system/blob/main/SECURITY.md): supported versions, response-time targets, safe harbor, npm provenance. - Packages, all at 4.6.0 published 2026-08-20: `@porsche-design-system/components-js`, `components-react`, `components-angular`, `components-vue`. - CDN: https://cdn.ui.porsche.com/porsche-design-system/components/ (version-pinned files) - 78 web components across layout, typography, actions, forms, overlays and data display. ## Open source - [Porsche Open Source Platform](https://opensource.porsche.com/) - [porscheofficial on GitHub](https://github.com/porscheofficial): cookie consent banner, technology radar, ESLint/Prettier configs, Terraform modules, research code. - [porsche-design-system on GitHub](https://github.com/porsche-design-system) ## Security - [security.txt](https://www.porsche.com/.well-known/security.txt): contact security@porsche.de, expires 2027-03-31. - [Information security policy](https://www.porsche.com/international/information-security/) - Note: the copy at https://identity.porsche.com/.well-known/security.txt expired 2025-12-31 and names a different contact (vulnerability@porsche.de). ## Optional - [Newsroom](https://newsroom.porsche.com/) - [Terms of use](https://developer.porsche.com/terms) - [Privacy policy](https://developer.porsche.com/privacy-policy)
