Buildkite vs GitLab CI: What are the differences?
Introduction
Here, we will discuss the key differences between Buildkite and GitLab CI. Buildkite and GitLab CI are both popular continuous integration (CI) tools used in software development. While they share some similarities, there are several important differences that set them apart.
-
Integration with GitLab repositories: Buildkite can integrate with GitLab repositories, but it is not limited to GitLab. It can also integrate with other version control systems like GitHub or Bitbucket. GitLab CI, on the other hand, is tightly integrated with GitLab, making it a seamless choice for GitLab users who want to keep their development process within the GitLab ecosystem.
-
Pipeline Configuration: Buildkite uses a YAML-based configuration file called "pipeline.yml" to define the CI/CD pipelines. The configuration allows a flexible and customizable approach. GitLab CI also uses a YAML-based configuration file called ".gitlab-ci.yml". However, GitLab CI provides a set of predefined keywords and configurations that make it easier to set up CI/CD pipelines without requiring extensive YAML knowledge.
-
Scalability and Parallelism: Buildkite offers excellent scalability and parallelism capabilities. It allows users to split their jobs across multiple agents and run them in parallel, making it suitable for large-scale CI/CD workflows. GitLab CI also supports parallelism but may have limitations depending on the GitLab instance and licensing.
-
User Interface and Usability: GitLab CI is tightly integrated into the GitLab platform, providing a unified user interface (UI) for managing repositories, issues, merge requests, and CI/CD pipelines. On the other hand, Buildkite provides a separate web interface dedicated solely to managing CI/CD pipelines. This separation allows Buildkite to have a more focused and streamlined UI for CI/CD workflows.
-
Community Support: GitLab CI has a large and active community behind it due to the popularity of the GitLab platform. Users can find extensive documentation, forums, and resources for troubleshooting and getting help with GitLab CI. Buildkite also has a supportive community, but it may not have the same breadth and depth of resources as GitLab CI.
-
Pricing and Deployment: Buildkite offers a hosted SaaS solution, as well as self-hosted options for on-premise deployment. It has a pricing model based on the number of concurrent build agents used. GitLab CI, on the other hand, is part of the GitLab platform, which offers a variety of deployment options, including a free self-hosted Community Edition and a paid self-hosted Enterprise Edition. The pricing for GitLab CI is typically based on the GitLab license chosen.
In summary, Buildkite and GitLab CI differ in their integration capabilities, pipeline configuration approaches, scalability, user interfaces, community support, and pricing/deployment options. The choice between the two will depend on specific requirements and preferences of the development team.
