The text provides a detailed comparison of several CI/CD platforms, focusing on their free-tier offerings, including GitHub Actions, Circle CI, Travis CI, and GitLab CI. It evaluates these platforms based on documentation quality, compute power, available disk space, build minutes, and performance speed, with Circle CI generally outperforming the others, particularly in terms of resource availability and speed. GitHub Actions is praised for its convenience when integrated with GitHub-hosted code, while Travis CI is noted for its initial free credit system, which expires after the first month. GitLab CI struggles with disk space limitations, impacting its performance in benchmark tests. Despite Travis CI's favorable impression, its limited free usage places GitLab in a better position for long-term value. The text also highlights Earthly, a tool aimed at improving build processes across different CI/CD platforms, suggesting its utility in adapting to changing free plan conditions.
