Episerver

Episerver is a digital experience platform (DXP) vendor that rebranded to Optimizely in 2021 after Episerver acquired Optimizely; the developer surface now ships under the Optimizely brand. The platform combines content management (CMS / Content Cloud), a headless Content Delivery and Content Management REST API, the Optimizely Graph (Content Graph) GraphQL API, Commerce (Configured Commerce and Commerce Connect), Feature Experimentation and Web Experimentation, the Optimizely Data Platform (ODP), the Content Marketing Platform (CMP), and Opti ID for unified OIDC identity. Developers integrate via first-party SDKs for JavaScript, React, Python, Java, C#/.NET, Ruby, PHP, Go and Swift, the EPiServer.CMS .NET libraries on NuGet, REST and GraphQL APIs, and webhooks. This profile was seeded as a portfolio lead and enriched by the API Evangelist pipeline from Optimizely's public developer documentation.

Episerver publishes 3 APIs on the APIs.io network. Tagged areas include Company, Enterprise, Content Management, Digital Experience Platform, and CMS.

The Episerver catalog on APIs.io includes 1 event-driven AsyncAPI specification.

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.

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 github.com/api-evangelist/episerver: open an issue to ask a question, or submit a pull request to add artifacts.
