Understand how Buildkite differs to CircleCI, why it’s a popular alternative.
Buildkite provides a SaaS platform to define and visualize pipelines and an agent to execute jobs on customer-managed infrastructure.
CircleCI Cloud features fully SaaS pipelines and task execution.
By default, Buildkite agents are self-hosted. Open source, no limits.
Premium Customers Only
Self-hosted options are available only in enterprise plans.
Pipelines can be defined via an in-UI step builder, dynamically via CLI utility, or as a YAML file in your source repository.
Define pipelines via a YAML configuration file in your repository.
Self-hosted agents give you full control to parallelize your CI tasks at any scale.
Free plans can run one job at a time, with concurrency limits in higher tiers.
Support for buildkite-hosted, github-hosted, or custom user-defined plugin sources.
CircleCI favors built-in functionality over modular plugins. Additional pipeline automation can be imported from a CircleCI-hosted registry.
