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.
|Security & Privacy
Buildkite’s self-hosted agent lets you keep sensitive data behind your firewall. When you host your runners, your code never leaves your servers!
CircleCI runners check code into isolated ephemeral sandboxes on vender-hosted infrastructure.
Buildkite charges a per-seat price with the option of enterprise support at larger scale.
