CircleCI is a continuous integration and delivery (CI/CD) platform for automating software builds, tests, and deployments. The CI/CD paradigm establishes version control repositories as the source of truth for your deployments. It also helps teams quickly ship new features and fixes by defining pipelines that help ensure the stability and resilience of your services through testing and automation.
