GoCD

GoCD is an open source, self-hosted CI/CD server for modelling multi-stage delivery pipelines, with a value stream map that traces each change to production.

GoCD helps a release team follow each commit through build, test and deploy, and spot inefficiencies along the way. Work is modelled as pipelines made of stages and jobs, and one pipeline can feed the next. The value stream map shows that entire path to production in a single view. GoCD is a community project maintained by volunteers and sponsored by Thoughtworks Inc. Config repositories keep pipeline definitions in YAML or JSON under version control, and pipeline templates package a shared workflow with parameters. A Timer Trigger schedules runs from a cron expression, and manual approvals between stages can be limited to named users. Environments group pipelines with the agents that run them, on the team's own machines or as elastic agents in a data center or the cloud. Jobs run in parallel, and one job can spawn several instances or run on every agent. Artifacts uploaded after each job are fetched by later stages, while the stage duration chart tracks passed and failed runs over time. GoCD suits platform and release engineers who model complex, multi-stage delivery workflows. Teams that must keep build infrastructure in house install the server on Linux, Windows, macOS or Docker. Release managers who must show what is deployed where find every deployment on each stage's details page. GoCD is open source software under the Apache License 2.0, which a team downloads, installs and operates itself. Help comes from the community in the GoCD Google group and GitHub Discussions. Teams run GoCD for continuous delivery with fan-in and fan-out between pipelines, from a build through test stages to deployment. Pipelines deploy to cloud environments such as Kubernetes, Docker and AWS. Other tools connect through curated plugins and the plugin API, which the project designs to stay non-breaking across upgrades. When a release stalls, the value stream map shows which stage holds the commit and which jobs ran before it.
