Are you referring to continuous integration? Cont delivery? Just stacks? If you're referring to some platforms..

CircleCI http://circleci.com as a continuous integration and deployment platform - they automate the build, test, and deploy process.

LaunchDarkly http://launchdarkly.com if you're looking to feature flag your builds and automate rollouts.

Gradle http://gradle.org is an open source build automation system that builds upon the concepts of Apache Ant and Apache Maven and introduces a Groovy-based domain-specific language (DSL) instead of the XML form used by Apache Maven of declaring the project configuration.
