OpenAPI Generator vs Scalingo: at a glance
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.
What is Scalingo?
Scalingo is back to routine runtime updates after its October router incident.
Scalingo is a European PaaS that keeps runtimes close to upstream. After a week of incident response that included router filters for Brotli and multipart requests, the changelog is back to buildpack updates: new Node.js versions, two rounds of JDK releases, Composer 2.11, fresh Python defaults and, on November 2, nginx 1.31.8 mainline. Python 3.11 is now deprecated.

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.
Scalingo
5.0DEVOPS
Scalingo is back to routine runtime updates after its October router incident.
◆ Current state
Scalingo is a European PaaS that keeps runtimes close to upstream. After a week of incident response that included router filters for Brotli and multipart requests, the changelog is back to buildpack updates: new Node.js versions, two rounds of JDK releases, Composer 2.11, fresh Python defaults and, on November 2, nginx 1.31.8 mainline. Python 3.11 is now deprecated.
◆ Where it's heading
The changelog has returned to its normal rhythm of runtime currency. The Python 3.11 deprecation is the one item that will require customer action.
◆ Prediction
Expect more buildpack updates weekly and, at some point, a removal date for Python 3.11; whether the Brotli block on existing Node.js apps is lifted is unclear.
