Exoscale vs OpenAPI Generator
A side-by-side editorial comparison of Exoscale and OpenAPI Generator — release velocity, themes, recent moves, and the top alternatives to consider.
Exoscale vs OpenAPI Generator: at a glance
What is Exoscale?
Exoscale lets customers keep their own encryption keys outside its cloud.
Exoscale, a European cloud provider, opened a private preview of KMS External Key Store on 3 November: customers connect Exoscale KMS to their own HSM or key manager through a proxy they host, and Exoscale never sees the key material. It implements the AWS KMS XKS proxy API, so existing proxies work unchanged. This follows a free VPC in every zone in October, object-storage lifecycle rules, asymmetric KMS keys and cheaper IPv6 load balancing.
What is OpenAPI Generator?
OpenAPI Generator keeps a 240-change release cadence across dozens of languages
OpenAPI Generator ships stable releases every few weeks to two months, each with 150 to 240 changes across generators for C#, C++, Go, Java, Kotlin, Dart and many more. 7.26.0 fixes nullable allOf handling in OpenAPI 3.1, exposes schema tracking in the Gradle plugin, adds .NET 10 support for aspnetcore and a Boost.Beast HTTP/1.1 server generator for C++. 7.25.0 before it added vendor override injection and splitOperationsByContentType.

Exoscale lets customers keep their own encryption keys outside its cloud.
◆ Current state
Exoscale, a European cloud provider, opened a private preview of KMS External Key Store on 3 November: customers connect Exoscale KMS to their own HSM or key manager through a proxy they host, and Exoscale never sees the key material. It implements the AWS KMS XKS proxy API, so existing proxies work unchanged. This follows a free VPC in every zone in October, object-storage lifecycle rules, asymmetric KMS keys and cheaper IPv6 load balancing.
◆ Where it's heading
KMS has moved fast: asymmetric keys in early October, external keys four weeks later. Together with VPC and lifecycle rules, Exoscale is closing gaps against the hyperscalers, and XKS points its pitch at sovereignty-bound customers who need to prove the provider cannot decrypt their data.
◆ Prediction
XKS will likely widen from private preview to general availability, and the next steps are probably more services encrypting with KMS keys; the entries don't say which services or when.
OpenAPI Generator
2.5DEVOPS
OpenAPI Generator keeps a 240-change release cadence across dozens of languages
◆ Current state
OpenAPI Generator ships stable releases every few weeks to two months, each with 150 to 240 changes across generators for C#, C++, Go, Java, Kotlin, Dart and many more. 7.26.0 fixes nullable allOf handling in OpenAPI 3.1, exposes schema tracking in the Gradle plugin, adds .NET 10 support for aspnetcore and a Boost.Beast HTTP/1.1 server generator for C++. 7.25.0 before it added vendor override injection and splitOperationsByContentType.
◆ Where it's heading
The core keeps absorbing OpenAPI 3.1 semantics while each language generator takes fixes from its own maintainers. New generators and framework versions arrive steadily, and breaking changes ship with fallbacks.
◆ Prediction
OpenAPI 3.1 normalisation fixes have appeared in every recent release, so expect them in the next one too.
