Buildbot vs Concourse: What are the differences?
Developers describe Buildbot as "Python-based continuous integration testing framework". BuildBot is a system to automate the compile/test cycle required by most software projects to validate code changes. By automatically rebuilding and testing the tree each time something has changed, build problems are pinpointed quickly, before other developers are inconvenienced by the failure. On the other hand, Concourse is detailed 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.
Buildbot and Concourse can be categorized as "Continuous Integration" tools.
"Highly configurable builds" is the top reason why over 8 developers like Buildbot, while over 8 developers mention "Real pipelines" as the leading cause for choosing Concourse.
Buildbot and Concourse are both open source tools. Buildbot with 3.98K GitHub stars and 1.36K forks on GitHub appears to be more popular than Concourse with 3.92K GitHub stars and 472 GitHub forks.
According to the StackShare community, Concourse has a broader approval, being mentioned in 18 company stacks & 17 developers stacks; compared to Buildbot, which is listed in 7 company stacks and 6 developer stacks.
