Faster CI.
More cores.
Less waiting.
On-demand x64 and ARM64 runners from 2 to 64 vCPU. Spot pricing — up to 85% cheaper than GitHub hosted. If you were on BuildJet, you can migrate in about five minutes.
Bottlenecked
by compute?
If your CI is bottlenecked by compute, more cores fix it.
Large parallel test suites that take 20+ minutes on a 2-core runner.
Docker image builds that are CPU-bound and benefit from more cores.
Compilation-heavy builds (Rust, C++, Go) that scale with core count.
ARM-native testing for software that ships to Graviton or Apple Silicon.
The typical alternative is either waiting on slow runners or provisioning your own and absorbing the maintenance overhead. Neither is great.
CPU Pricing
Live per-minute rates for x64 and ARM64 CPU runners. Auto-refreshes every 30 seconds.
x64
or ARM64.
Pick one.
Add an architecture=arm64 flag and you get Graviton instead of Intel/AMD. That's the entire difference.
Large parallel test suites
If your test suite takes 20 minutes on a 2-core runner, a 16-core machine with more RAM will cut that down significantly. Most test frameworks can parallelise across cores with a single flag.
Fast Docker builds
Docker layer building is CPU-bound and benefits directly from more cores. A 32-core runner can cut a large image build from 15 minutes to 3.
Compilation-heavy builds
Rust, C++, Go — anything with heavy compile steps scales almost linearly with core count up to a point.
ARM-native testing
If you're shipping software that runs on ARM (Apple Silicon, AWS Graviton, Raspberry Pi), testing on a real ARM runner catches issues that cross-compilation misses.
