Comparison
Runnable vs. Buildkite
Buildkite is a good product with a real philosophy: you bring the compute, they orchestrate it, and they charge per seat. Runnable takes the opposite position on both. Here is the difference, including the cases where Buildkite is the better answer.
The structural difference is seats
Buildkite Pro is $30 per active user per month. That cost scales with your engineering headcount whether or not those engineers push often. Runnable charges for compute and includes unlimited users, so growing the team changes nothing.
| Team size | Buildkite seats alone | Runnable seats |
|---|---|---|
| 3 developers | $90/mo | $0 |
| 5 developers | $150/mo | $0 |
| 10 developers | $300/mo | $0 |
| 25 developers | $750/mo | $0 |
| 50 developers | $1,500/mo | $0 |
Before any compute is billed on either side.
A worked total, for a ten-person team
Runnable at the plan its own checker would recommend, against Buildkite Pro with hosted Linux agents at $0.004 per vCPU-minute. One normalized minute is one minute on 2 vCPU, so it bills as two vCPU-minutes on the Buildkite side.
| Monthly CI | Runnable | Buildkite (10 devs) | Difference |
|---|---|---|---|
| 1,000 min | Starter $29 | $308 | 10.6× cheaper |
| 4,000 min | Pro $99 | $332 | 3.4× cheaper |
| 12,000 min | Scale $299 | $396 | 1.3× cheaper |
| 25,000 min | Scale $299 | $500 | 1.7× cheaper |
The gap narrows as CI volume rises and widens as the team grows, because Buildkite's compute is cheaper per vCPU-minute and its seats are not. If your team is small and your CI is enormous, run the numbers again — that is the case where Buildkite competes hardest on price.
Four differences that are not price
You are not billed per developer
Runnable
Every plan includes unlimited users. Adding the eleventh engineer costs nothing.
Buildkite
Pro is $30 per active user per month. A ten-person team pays $300 before a single job runs.
You do not run the agents
Runnable
Every job gets a clean, single-use Linux machine. There is no agent fleet to size, patch, or wake up at 3am.
Buildkite
Self-hosted agents are free but they are yours to operate — the infrastructure, the autoscaling, the security patching, and the pager.
Your workflow files do not change
Runnable
Runnable reads GitHub Actions-compatible YAML. Migration moves the file; it does not rewrite it.
Buildkite
Buildkite uses its own pipeline format. Migrating means rewriting every pipeline and re-learning the model.
Your code is never used to train models
Runnable
Source, diffs, logs, artifacts, and secrets are never used to train or improve AI models. Every plan, no opt-out required.
Buildkite
Review their current terms yourself — we will not characterise another vendor's data practices for them.
When Buildkite is the better choice
There are real cases where the answer is Buildkite, and you should know them before migrating rather than after.
You need macOS or Windows runners. Runnable is Linux x64 only.
You need Windows, macOS, ARM, native job containers, or jobs longer than six hours. Runnable rejects those at validation rather than failing halfway through.
You want to run CI inside your own network on your own hardware. Self-hosted agents are a genuine strength, and Runnable has no equivalent.
You already have working Buildkite pipelines and no reason to move. Rewriting working CI is rarely worth it.
You need unlimited concurrency on your own machines. Runnable's concurrency is bounded by plan.
If your repositories are on Entire
Entire's CI enrollment contract currently accepts only buildkite, so Buildkite is the incumbent answer there by default rather than by comparison. Runnable connects to Entire-native repositories and Entire mirrors directly, checking out through entire:// with a repository-scoped token. If that is your situation, the comparison above is the whole decision.
Buildkite pricing read from buildkite.com/pricing on 11 August 2026: Pro at $30 per active user per month, hosted Linux agents at $0.004 per vCPU-minute, self-hosted agents unlimited at no cost.
