Machine-readable comparison dataset for Jenkins vs Buildkite. Contains 140 attribute comparisons, 5 FAQ pairs.
Jenkins vs Buildkite — Attribute Category Vocabulary
Taxonomy of attribute categories used to classify comparison data for Jenkins vs Buildkite.
Jenkins has zero software licensing costs but requires 1-2 FTE DevOps engineers ($80k-120k/year) for maintenance. Buildkite costs $30-100/month for typical teams but eliminates DevOps overhead. For teams <10 engineers, Jenkins wins cost-wise. For teams >50 engineers, Buildkite typically costs less when factoring in DevOps salary.
Can I use Buildkite on-premise or airgapped?
No. Buildkite is SaaS-only and requires cloud connectivity. Jenkins can run entirely on-premise, in airgapped networks, or in regulated environments (HIPAA, FedRAMP). For government/defense/healthcare with strict data residency, Jenkins is the only viable option.
Which has better integration with GitHub/GitLab?
Both integrate well natively. Buildkite provides native GitHub/GitLab webhook support in the UI. Jenkins requires the GitHub Branch Source plugin (300k+ installs) or GitLab plugin. Buildkite is faster to set up (< 5 minutes); Jenkins requires plugin installation and configuration.
Jenkins requires manually provisioning and configuring build agents/nodes on your infrastructure. Buildkite provides elastic agent pools that auto-scale based on queue depth—agents spin up/down automatically. Buildkite's auto-scaling reduces operational overhead by 60-80% compared to Jenkins manual scaling.
Which is better for open-source projects?
Buildkite offers a generous free tier (5 agents, 100GB logs/month) for open-source projects. Jenkins is free but requires self-hosting infrastructure. For open-source teams without DevOps resources, Buildkite's free tier is significantly better. For large OSS projects with existing infrastructure, Jenkins is more cost-effective.
