Open-source Azure DevOps alternatives

Gitea is a software development service written in Go that you host yourself and that brings the usual tooling together in one place. It combines Git hosting, code management and review, issue tracking, project kanban boards, a wiki, team collaboration, a package registry and CI/CD, with the aim of being the easiest and least painful way to run your own code platform. Its topics place it in the same space as GitHub and GitLab.

Because it is written in Go, Gitea runs on any platform Go supports: Linux, macOS, the BSDs and Windows, across x86, amd64, ARM, RISC-V 64 and PowerPC processors. Package registries such as Maven, npm and Docker are mentioned in its topics, and its CI/CD system can reuse GitHub Actions workflows, which eases migration of existing pipelines. Documentation covers installation, administration and development.

The project is MIT licensed. You can try a public demo at demo.gitea.com, use the free service at gitea.com with a limited number of repositories, start a trial of the managed Gitea Cloud, or deploy the official container image on your own server. It suits teams and individuals who want control over their source code hosting.

Harness Open Source is a developer platform written in Go that bundles source code hosting, automated pipelines, hosted development environments and artifact registries in one product. The idea is to give a team a complete, self-run DevOps toolchain rather than separate services for repositories, builds and package storage.

Its hosted development environments are called Gitspaces, and the platform also includes registries for build artifacts. Harness is presented as the next generation of Drone: Drone focused only on continuous integration, whereas Harness adds code hosting and developer environments. The maintainers say the goal is eventual parity with Drone's pipeline capabilities so users can migrate, and a snapshot of Drone lives on a separate branch so it can keep developing.

You can run Harness locally from the published Docker image and open it on port 3000. The image stores its database and repositories in a volume, so a bind mount or named volume is strongly recommended to avoid losing data when the container stops. The project is Apache-2.0 licensed, with documentation at developer.harness.io.

GitLab is a platform for collaborating on code. This GitHub repository is a mirror of the Community Edition, written in Ruby on Rails, while the canonical source and all development take place on GitLab.com. Issues should be opened on the GitLab.com tracker rather than here. The platform manages Git repositories with fine-grained access controls, merge requests for code review, and per-project issue trackers, boards and wikis.

GitLab includes continuous integration and delivery pipelines to build, test and deploy applications. It follows an open-core model: most of the code is MIT-licensed, while files in the ee directory are proprietary but source-available. Three editions exist: Community Edition, free under the MIT Expat license; Enterprise Edition, with extra features aimed at organizations with more than 100 users and sold by subscription; and JiHu Edition for the Chinese market. A free trial of the Ultimate tier is available.

OneDev is a self-hosted platform that gathers Git hosting, issue tracking, pull requests, CI/CD, packages, a wiki and workspaces in one place. It is described as unified and autonomous, with AI teammates available to help with development work. The team develops OneDev on its own instance at code.onedev.io, where issues and pull requests are submitted.

The feature set emphasizes code review and quality. There is language-aware symbol search and navigation within any commit, fast code search with regular expressions, a Renovate integration that updates dependencies through pull requests which can merge automatically after approval or passing tests, and code annotated with coverage and problems found in the CI/CD pipeline. Discussions can be started on any code selection or diff and stay attached to the code, and versatile protection rules can require reviews or CI verification when particular users change particular files on particular branches. Topics also mention kanban boards.

OneDev is written in Java and licensed under MIT. You host it yourself, which suits teams wanting an all-in-one alternative to stitching together GitHub-like hosting, CI and project tools. Tutorials and demos on the project site show features such as dependency updates and protection rules in action.

bk-ci, also called Blueking Continuous Integration (蓝盾), is a free and open-source CI service for automating build, test, and release workflows. It handles compiling, static code analysis, running tests to catch bugs early, and deployment and release. The documentation is available in Chinese and English, and the input lists its license only as other. It is written in Kotlin and Java.

The platform is described as eight core services: pipelines that visualize a team's development process, code checking powered by BK-CodeCC, a code repository service that links existing source hosting, credential management, environment management for build machines, a store of pipeline plugins and templates, compile acceleration for C/C++ and Unreal Engine builds, and an artifact repository supporting formats such as Maven, npm, PyPI, Docker, Helm, and NuGet on COS or S3 storage. A cloud desktop service is also listed.

The README warns that the master branch can be unstable and that users should install from releases. bk-ci suits enterprises, particularly Chinese-speaking teams and game studios, that want a self-managed CI platform covering pipelines, artifacts, and build acceleration.

Choerodon is an open-source platform that aims to cover the whole value chain of enterprise software delivery, from agile project management through to deployment, across local and cloud environments. It is built on established open-source technologies, including Kubernetes, Istio, Knative, GitLab and Spring Cloud, to give organizations a consistent experience whether they run on-premises or across hybrid and multi-cloud setups.

It provides a toolchain supporting DevOps practices across the Scrum workflow, from planning and programming through building, testing, publishing and operations, together with a suite of Spring Cloud-based microservice application frameworks to help teams build microservices faster. The README notes that Choerodon 2.0 brought improvements to open-source code management, artifact library management, CI/CD pipelines, container management, environment resources and application deployment, though this open-source edition does not include project management, test management or the knowledge base found in a separate trial environment.

Choerodon runs on Kubernetes and is written primarily around container and cloud-native tooling rather than a single language. It is released under the Apache-2.0 license, with documentation, a forum and release notes maintained by the Open Hand organization behind the project.
