Hosted Arm64 CI
GitHub's windows-11-arm runner builds and tests on real Arm64
Shipping a native build used to mean buying Arm hardware for the build farm. GitHub now hosts a Windows 11 Arm64 runner, so open-source projects can compile and run their tests on the target architecture for free.
Key points
-
Generally available
The windows-11-arm runner left preview in August 2025 for public repositories.
-
Test on target
Cross-compiling on x64 cannot run the result. A native runner executes your test suite on Arm64.
-
Private repositories
Private repos need larger paid runners or a self-hosted Arm machine.
