Concourse vs Heroku CI: 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, Heroku CI is detailed as "Fast, low-setup CI that’s easy to use". On every push to GitHub, Heroku CI runs your tests in a disposable Heroku app, so there’s never a wait time for a free CI worker. Tests run fast, on Performance dynos.
Concourse and Heroku CI belong to "Continuous Integration" category of the tech stack.
