When Microsoft bought GitHub they cancelled GitHubs own early CI effort and rebranded the existing Azure DevOps as GitHub Actions.

The GitHub Actions runner source code is all dotnet. GitHub was a Ruby shop.

IIRC Azure DevOps was the “dead one”, all new development only takes place on GitHub.

From my perspective, Azure Pipelines is largely the same as GitHub Actions. I abhor this concept of having abstract and opaque “tasks”.

The other way around. Azure DevOps is 1/2 a backend for Github these days. Github re-uses a lot of Azure Devops' infrastructure.
