Styra

Styra is the company that created Open Policy Agent (OPA), the Cloud Native Computing Foundation graduated policy engine, and commercialized it as Enterprise OPA and Styra DAS (Declarative Authorization Service) for policy-as-code authorization across Kubernetes, microservices, APIs, and data. Styra was acquired by Akamai in December 2024; the styra.com and docs.styra.com properties no longer resolve, but OPA remains the de facto standard for cloud-native authorization and the open-source technical surface (GitHub, published SDKs, the OpenAPI spec, and gRPC protobufs) is active. The Enterprise OPA / OPA REST API evaluates Rego policy decisions, batch decisions, and partial-evaluation "data filtering" that compiles authorization into UCAST or SQL conditions. Backed originally by Accel and Battery Ventures.

Styra publishes 5 APIs on the APIs.io network, including Batch API, Compile API, Data API, and 2 more. Tagged areas include Company, Cybersecurity, Authorization, Policy as Code, and Open Policy Agent.

Styra’s developer surface includes documentation, API reference, authentication, CLI, changelog, and 18 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Insurance 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.
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/. This rating is computed from github.com/api-evangelist/styra: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
