A CI/CD build server from JetBrains for automating builds, tests, and deployments, available self-hosted or as a cloud SaaS.

TeamCity is a continuous integration and delivery server built by JetBrains, supporting major version control systems and build and test tooling across most popular languages, running builds on a pool of distributed build agents. Teams use it as a self-managed alternative to hosted CI providers, or via JetBrains’ TeamCity Cloud.

It offers YAML-based pipeline configuration alongside its classic UI-driven build configurations, plus continuous-deployment features for release orchestration — serving as an alternative to CircleCI, GitHub Actions, and Travis CI for build and test automation, and to Octopus Deploy for release orchestration.
