Buildkite splits the difference: a hosted control plane that orchestrates agents running on your own infrastructure.

GitHub Actions is integrated CI with hosted or self-hosted runners; Buildkite is a hybrid where Buildkite hosts the pipeline UI/scheduler and you run the agents. That model is popular at scale. Here is the comparison.

## Comparison

|  | GitHub Actions | Buildkite |
| --- | --- | --- |
| Config | .github/workflows/*.yml | pipeline.yml + agent steps |
| Hosting model | GitHub-hosted or self-hosted | Hosted control plane + your agents |
| Pricing | Per-minute (hosted) | Per-user, compute on your infra |
| Ecosystem | Actions Marketplace | Plugins + your own tooling |
| Speed levers | Caching, larger/managed runners | Your agent fleet + dynamic pipelines |
| Scale control | Managed | High (you own the compute) |

## Pricing and model

Buildkite charges per user for the control plane while you pay your own cloud for agents - attractive for very large fleets that want control. GitHub Actions bundles compute into per-minute billing. Verify current per-seat pricing with Buildkite.

## Config and ecosystem

Buildkite shines at dynamic pipeline generation and massive parallelism on your hardware; Actions wins on GitHub-native integration and a larger off-the-shelf marketplace.

## Speed and runners

Buildkite gives control by making you run agents. If you prefer that control without the ops, GitHub Actions managed runners (e.g. Latchkey) deliver cheap compute ($0.0025/min at 2 vCPU vs $0.006 GitHub-hosted) with warm pools and self-healing - no agent fleet to maintain.

## Migrating between CI platforms: what actually costs time

- Pipeline syntax is the easy part and the part every comparison focuses on. Budget for it, then expect it to be the smallest line item.
- Secrets, OIDC trust relationships, and deploy credentials have to be recreated and re-approved, usually by a different team.
- Caching semantics differ enough that a naive port produces a pipeline that is correct and much slower.
- Required status checks and branch protection reference check names. Renaming them mid-migration blocks merges until the rules are updated.
- Run both in parallel on the same commits until the new one has been green for a full sprint. Cutting over on a green first run is how migrations get rolled back.

## The verdict

Choose Buildkite for maximum control over a large self-run agent fleet; choose GitHub Actions for integrated, low-ops CI. Managed runners give Actions teams Buildkite-like economics without running agents.
