# CircleCI

CircleCI is a CI/CD platform that builds, tests and ships code changes. Teams run pipelines on CircleCI compute or on self-hosted runners, and it can also be run entirely on the customer's own infrastructure. Smarter Testing runs only the tests a change affects, and Chunk works through flaky tests, tech debt and pipeline optimizations.
