Best for pricing: Jenkins
When it comes to pricing, Jenkins has a clear advantage as it is an open-source tool that comes at no cost to the user.
In contrast, while GitHub Actions usage is free for standard GitHub-hosted runners in public repositories and for self-hosted runners, it does incur a charge for private repositories.
Each private GitHub account receives a certain amount of free minutes and storage for use with GitHub-hosted runners, depending on the product associated with the account. Any usage beyond the included amounts is controlled by spending limits, with billing based on the execution minutes for hosted runners.
Jenkins emerges as the more budget-friendly option for those concerned about pricing, as its open-source nature means there are no direct recurring costs.
Best for hosting: GitHub Actions
When evaluating hosting options, GitHub Actions stands out as the more convenient choice for many users.
As a part of the GitHub ecosystem, GitHub Actions is hosted on GitHub, so you don’t need to worry about setting up and maintaining your own server. This saves time and effort and ensures seamless integration with your existing GitHub repositories and workflows.
Jenkins, on the other hand, requires self-hosting, which means you’re responsible for managing the server infrastructure. While this approach provides greater control over the environment and can be highly scalable based on your infrastructure choices, it also demands additional effort for setup, maintenance, and updates.
Ultimately, the best choice for hosting will depend on your specific needs and preferences. If you prioritize ease of use and a hands-off approach to server management, GitHub Actions is the way to go. However, if you require full control over your CI/CD environment and are prepared to manage the server infrastructure, Jenkins could be your better option.
Best for integration: Jenkins
When it comes to integration capabilities, Jenkins emerges as the top choice due to its extensive range of over 1800 community-contributed plugins and adaptability with various source code management systems.
As a mature and flexible CI/CD tool, Jenkins offers a vast and active community that has developed numerous plugins for integrating with other tools and systems. This means Jenkins can easily connect to various platforms, services, and environments, ensuring a versatile and customizable experience.
While tightly integrated with the GitHub platform, GitHub Actions may provide a different level of flexibility in terms of integration with other tools and systems. Although the GitHub Actions marketplace offers a considerable number of prebuilt actions, it only covers some of the possible integration requirements, particularly for users who work with diverse or niche tools and platforms.
If integration with a wide variety of tools and systems is a priority for your CI/CD workflows, Jenkins is the better choice. Its extensive plugin ecosystem and compatibility with any source code management system make it a highly adaptable and customizable solution for diverse development environments.
Best for scalability: Jenkins
As far as scalability goes, Jenkins holds the edge over GitHub Actions, primarily due to its self-hosted nature.
With Jenkins, you have full control over your server infrastructure, which allows you to scale your CI/CD environment for vertical or horizontal growth as needed. This flexibility means you can choose the size, performance, and configuration of your build environment, making it possible to optimize your CI/CD pipeline based on your project’s specific requirements.
In contrast, GitHub Actions relies on GitHub’s infrastructure, which can impose limitations on your CI/CD pipeline’s scalability. While GitHub provides a robust and reliable environment, its constraints may hinder your ability to scale your CI/CD pipeline to accommodate growing or fluctuating demands. Besides, you may encounter usage limits depending on your GitHub account type, which could further impact the scalability of your pipeline.
Therefore, if scalability is a top priority for your CI/CD pipeline, Jenkins is the superior option. Its self-hosted infrastructure provides the flexibility and control necessary to adapt your pipeline to your project’s evolving needs, ensuring optimal performance and efficiency throughout the development lifecycle.
Why shouldn’t you use GitHub Actions or Jenkins?
While both GitHub Actions and Jenkins offer valuable features and benefits for CI/CD pipelines, they may not be suitable for everyone. It’s essential to understand the limitations of each tool and determine whether they align with your project requirements and preferences.
Who shouldn’t use GitHub Actions?
GitHub Actions may not be the best choice for developers or teams who:
