Build Hub: level up GitHub Actions with infrastructure optimized for mobile
For GitHub Actions teams who are serious about quality mobile app development.
Fast, reliable builds with no messy migration
Consolidating CI/CD on GitHub might make business sense, but building mobile apps on slow, generic runners kills release momentum.
No worries. Bitrise has you covered. Keep GitHub Actions as your CI orchestrator. Run your builds on infrastructure tailored for mobile.
Plug-and-play build infrastructure for GitHub Actions
Keep your devs in flow with build machines that can handle heavy iOS and Android workloads. Just point mobile jobs to Build Hub and watch your wait times shrink.
1. Connect
Define a Build Hub machine pool to your GitHub Enterprise or Organization.
2. Point
Point your mobile builds to Build Hub by updating your YAML to runs-on: bitrise-m4-pro.
3. Run
Your mobile builds now route instantly to pre-warmed virtual machines on Bitrise Build Hub.
Consolidate without compromise
Mobile teams shouldn’t be stuck on subpar infrastructure. With Bitrise Build Hub, they get the hardware and build environments they need to ship quality apps fast.

Frequently Asked Questions
Do I need to migrate off GitHub Actions to use Bitrise Build Hub?
No, Build Hub works with your existing GitHub Actions workflows. You keep GitHub Actions as your CI orchestrator and upgrade to build execution infrastructure provided by Bitrise. No complex platform migration, no workflow rewrites, and most teams see results within days.
What's the difference between Build Hub and GitHub's Mac runners?
GitHub's Mac runners use older M1/M2 hardware with 14GB RAM limits, and their Xcode updates historically can take days or even weeks. Build Hub offers the latest M4 Pro machines, owned and maintained by Bitrise. We also provide same-day Xcode releases (within 24 hours), and pre-warmed VMs with all essential mobile tooling already installed. Long story short: better hardware, faster updates, no wait times.
How quickly can I get started with Build Hub?
Most teams complete a proof-of-concept in 7-14 days, with side-by-side metrics comparing GitHub Hosted Runners to Bitrise Build Hub. Setup is plug-and-play: route mobile jobs to Build Hub runners while keeping everything else on your existing infrastructure.
Does Build Hub support Linux builds?
Build Hub offers eight standard Linux machine types from 4 to 48 vCPU, plus support for custom vCPU setups with granular sizing options, so you're not overpaying for specs you don't need. Our Linux machines run 20% faster than Google Cloud Platform compute-optimized instances with better price-performance ratios. We can support any even vCPU setup between 2 and 96.
Can I use Build Hub with my own caching solution?
Yes, though Build Hub is also fully compatible with Bitrise's unique co-located Build Cache, which delivers lower latency and eliminates network egress costs since cache and compute live in the same data center. Build Cache for Xcode, Gradle, and Bazel can cut build times by up to 90%.
Can I use Build Hub with a different CI provider (not GitHub Actions)?
Our goal is to make Build Hub future-proof and provider-agnostic for any team that needs best-in-class build infrastructure. We’re planning to roll out support for other CI platforms in the second half of 2026. If you need support sooner, don’t hesitate to get in touch.
What kind of build time improvements should I expect?
Customer benchmarks show build times dropping from 30+ minutes to as little as 5 minutes. Exact improvements depend on your current infrastructure and build complexity, but M4 Pro hardware combined with pre-warmed VMs and mobile-optimized stacks consistently delivers 30-50% faster builds versus GitHub-hosted runners. One customer found that even our small-sized Macs provided 30% build time reductions over GitHub’s XL macOS runner.
How does infrastructure maintenance work?
Build Hub means zero maintenance on your end. Bitrise handles Mac hardware, OS updates, Xcode installations, beta releases, SDK updates, and virtualization. Same-day Xcode updates mean your team never waits for toolchain availability: we aim to deliver new versions within 24 hours of Apple's release.
What if I need to debug a build issue?
Build Hub includes remote debugging access, so you can VNC and SSH into runners to troubleshoot environment issues without filing tickets or waiting for support. Enterprise controls give you full visibility and access when you need it.
Does Build Hub support both iOS and Android?
Yes. Pre-configured mobile stacks include iOS simulators, Android emulators, Fastlane, CocoaPods, Gradle, and other mobile tooling. Both Mac and Linux runners come ready for mobile development without additional setup.
What happens if I outgrow Build Hub?
Build Hub is designed to scale with you. Instant capacity upgrades mean you never hit resource limits. If your needs evolve, you can add Bitrise CI for more advanced orchestration or introduce Release Management for automated app store distribution.
