GitHub Actions
Free minutes / usage-based
CircleCI is a dedicated CI/CD platform with powerful pipelines and flexible runners. GitHub Actions is CI/CD built into GitHub with a huge marketplace of reusable actions. CircleCI wins on dedicated power and flexibility; GitHub Actions wins on native integration and ecosystem.
Pick CircleCI if you want a dedicated, powerful CI/CD platform with flexible pipelines and runners.
Pick GitHub Actions if you are on GitHub and want CI/CD natively integrated with a huge marketplace.
CircleCI and GitHub Actions both automate building, testing, and deploying code, but they differ in approach. CircleCI is a dedicated CI/CD platform with powerful, configurable pipelines, flexible execution environments, and strong performance features for teams that want a focused CI/CD tool. GitHub Actions is built directly into GitHub, so CI/CD lives next to your code, with a massive marketplace of reusable actions and seamless repo integration.
On price, both offer free usage with usage-based paid plans beyond included minutes. The choice is mostly dedicated CI/CD power and flexibility (CircleCI) versus native GitHub integration and ecosystem (GitHub Actions).

Things neither product's marketing page leads with.
CircleCI offers dedicated power and works across Git hosts, but it is a separate tool from your repo.
GitHub Actions is seamlessly integrated with the biggest marketplace, but it is most natural only if you are on GitHub.
For dedicated CI/CD CircleCI wins; for GitHub-native workflows Actions wins.
