Which is cheaper for a small team with 10-20 private repositories?
GitHub Actions is significantly cheaper. With 2,000 free build minutes monthly included on GitHub Free plans, most small teams stay within the free tier. At typical usage (100-200 minutes/month per repo), costs remain $0. Buildkite costs $50/month minimum regardless of usage, making it uneconomical unless you exceed 6,250 build minutes monthly or need self-hosted infrastructure.
Can I run Buildkite on AWS/Kubernetes infrastructure?
Yes. Buildkite agents run on any infrastructure you control—AWS EC2, Kubernetes clusters, on-premise servers, or hybrid setups. You install the agent binary and it connects to Buildkite's cloud platform. GitHub Actions only offers GitHub-hosted runners; you cannot self-host them or run custom infrastructure.
On GitHub Actions, the build fails after 360 minutes (6 hours) with a timeout error. On Buildkite, there is no enforced limit—the job runs as long as needed on your self-hosted agent. This makes Buildkite essential for long-running workloads like large-scale testing, data processing, or compilation jobs.
How many pre-built integrations does each platform offer?
GitHub Actions has 11,000+ community-maintained actions in its marketplace covering Docker, testing, deployment, and cloud services. Buildkite has ~500 official plugins plus community contributions. GitHub Actions' larger ecosystem makes onboarding faster for common tasks; Buildkite's focused plugin set emphasizes stability over quantity.
Which is better for compliance-heavy industries (healthcare, finance)?
Buildkite is the clear choice. Self-hosted agents let you maintain air-gapped networks, meet data residency requirements, and achieve HIPAA/FedRAMP compliance. GitHub Actions runs builds on GitHub's infrastructure, which violates many compliance frameworks requiring complete data isolation. Buildkite's on-premise model aligns with regulated industry requirements.
