Our GUI log dialog is intuitive, looking very similar to what Subversion and CVS users expect. As shown, bugs can be associated with changes. Our storage format directly supports that: there’s no need to massage important metadata into specially formatted commit messages. Note also that many revisions can be expanded out to see the local commits made to deliver each larger change. -

Concourse
Concourse
Concourse is an open-source continuous thing-doer. Built on the simple mechanics of resources, tasks, and jobs, Concourse presents a general approach to automation that makes it great for CI/CD. A Concourse pipeline is like a distributed, continuous Makefile. Each job has a build plan declaring the job's input resources and what to run with them when they change. Your pipeline is then visualized in the web UI, taking only one click to get from a failed job to seeing why it failed. The visualization provides a "gut check" feedback loop: if it looks wrong, it probably is wrong. Jobs can depend on other jobs by configuring passed constraints. The resulting chain of jobs and resources is a dependency graph that continuously pushes your project forward, from source code to production. All configuration and administration is done using the fly CLI. The fly set-pipeline command pushes the config up to Concourse. Once it looks good, you can then check the file in to source control.Starting Price: Free
