GitHub Actions vs. Jenkins: Popular CI/CD Tools Comparison

Continuous Integration and Continuous Delivery (CI/CD) pipelines have transformed Software Development Life Cycle (SDLC) by automating building, testing, and deployment processes. Jenkins is a popular self-hosted CI/CD platform with an extensive ecosystem of plugins, while GitHub Actions simplifies CI/CD by allowing developers to create workflows natively within GitHub. Both tools offer customization options, support for multiple programming languages, and the ability to use self-hosted runners. However, Jenkins has a steeper learning curve and requires manual scaling and maintenance, while GitHub Actions is easier to set up but can become costly for large-scale usage on private repositories. Spacelift offers additional features such as policy enforcement, stack dependencies, self-service infrastructure, and drift detection, making it a suitable choice for orchestrating provisioning, configuration, and governance across cloud-based infrastructures.
