Best open source DevOps and CI/CD tools for developers

Building a stable development pipeline is essential to software delivery. By self-hosting your Git repositories, build servers, and container dashboards, you safeguard your codebase intellectual property and control deployment security.

With self-hosted infrastructure, development teams can run infinite build testing runs without compute limits, deploy secure staging environments within private networks, and avoid developer seat licensing fees.

This guide lists the top self-hostable tools that assist engineers, system administrators, and developers in hosting source code and managing containers.
