# TeamCity TeamCity is a free\* CI/CD platform developed and maintained by JetBrains. The on-premises professional version gives us powerful features which can be used in an enterprise environment (though it might not fit your enterprise's scale). TeamCity will allow us to pull public, and private repositories from GitHub and GitLab respectively, which makes it fairly flexible when using other people's tools, and customising it to our needs. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://blog.securescape.cc/offensive-security/red-team/offensive-development/offensive-devops/teamcity.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
