Concourse vs Github Actions: What are the differences?
Developers describe Concourse as "Pipeline-based CI system written in Go". Concourse's principles reduce the risk of switching to and from Concourse, by encouraging practices that decouple your project from your CI's little details, and keeping all configuration in declarative files that can be checked into version control. On the other hand, Github Actions is detailed as "Automate your workflow from idea to production". It makes it easy to automate all your software workflows, now with world-class CI/CD. Build, test, and deploy your code right from GitHub. Make code reviews, branch management, and issue triaging work the way you want.
Concourse and Github Actions belong to "Continuous Integration" category of the tech stack.
Concourse is an open source tool with 5.06K GitHub stars and 622 GitHub forks. Here's a link to Concourse's open source repository on GitHub.
