Compare list runtime costs.
Pick a monthly runtime and a runner size.
List runtime costs before allowances, credits, plan fees, or add-ons, assuming equal runtime. Charts use WarpBuild managed Linux x64 list rates. ARM rates differ. BYOC's $0.002/min is a platform fee plus your own cloud bill, not an all-inclusive runner price. Cache and snapshot add-ons are excluded from the runtime calculator. Free credits and actual job duration can change the bill. Equal CPU and RAM allocations do not imply equal processors, disk, networking, or speed. These are not predicted bills or measured job performance. Sources and checked date.

Cut recurring Linux runtime costs as your pull-request volume grows.
Choose Celesto if
- You want 83% lower Linux x64 list runtime rates at matching CPU and RAM
- Dependency caches fit within the included per-repository limits
- Your jobs fit within 8 vCPU and 32 GB on Linux x64
- You want managed runners without operating a cloud account for CI
Stay on WarpBuild if
- You need ARM, Windows, macOS, or larger Linux runners
- Your runner needs a 150 GB local disk even at the smallest size
- Your policies require runners in your AWS, GCP, or Azure account
- Snapshots or remote Docker builders save enough execution time to justify the added cost
Switch in one line.
Install the GitHub App, then swap the runner label. Keep compatible workflow steps and cache configuration; logs stay in GitHub Actions. Celesto stores caches separately, so expect an initial cache miss.

Linux x64 jobs include actions/cache and setup-node/setup-python caching without changes to compatible cache steps. Cache storage has no separate charge. Default per-repository limits are 5 GiB on trial and promotional credit and 25 GiB on paid credit; caches expire after 7 idle days. CI runtime consumes workspace credit.
Docker Engine, Buildx, and Compose are preinstalled. Docker builds, Compose workflows, and GitHub service containers are verified. Validate Docker actions and whole-job containers before migrating. Docker’s explicit --cpus flag failed the documented preflight.
No. Each job starts fresh. Use registry caches or portable archives through actions/cache to reuse layers. Direct BuildKit type=gha,version=2 cache export failed the documented preflight.
At 2 vCPU and 8 GB, Celesto costs $0.000667/min and WarpBuild managed Linux x64 costs $0.004/min: 83% less per runtime minute. The same ratio holds at the matched 4- and 8-vCPU sizes. This excludes credits, cache add-ons, and differences in actual job runtime.
No. The numeric chart uses managed Linux x64 runners. WarpBuild's published BYOC Linux platform fee is $0.002/min, with infrastructure billed by your cloud provider. Compare that combined cost separately.
No. We have not published a matched benchmark against WarpBuild. Our comparison matches allocated CPU and memory and compares published runtime prices. CPU model, disk, network, and cache behavior can all affect completed-job cost.
