An Initiative to Streamline Software Development on Arm with Free Cloud Resources

The Works on Arm initiative enables developers to build, test, and optimize projects on the Arm64 architecture by providing free-of-cost access to Arm based developer platforms, cloud instances, and CI/CD environments. Arm has partnered with cloud platform providers to make Neoverse-based compute available for cloud-to-edge solutions, while offering choice and flexibility.


Developer Offerings:

Works on Arm Testimonials

"Adoptium produces Eclipse Temurin binaries on both 32 and 64 bit Arm platforms. Most of these systems are from the Works on Arm initiative and are currently supporting four parallel versions of OpenJDK builds, performing testing across a broad range of Linux distributions with ease. The additional systems provided by the Works on Arm initiative resulted in our Linux on Arm build and test cycle being faster than many other platforms." Stewart Addison, Eclipse Adoptium Project
"Works on Arm is helping Debian packages to be built on Arm through Continuous Integration (CI) and to execute automated tests required for a stable release. More than 3 million CI jobs have run on these platforms as of October 2022. Debian thanks Works on Arm for this wonderful support." Santiago Ruano Rincón, Debian Project
"The hardware provided by Works on Arm has been instrumental in providing resources to the open-source DynamoRIO project for both automated testing and interactive development for the AArch64 platform. AArch64 is a key target for the DynamoRIO community. Without this hardware we would be limited to emulation which has many shortcomings and restrictions including being substantially more difficult to debug and being unable to successfully run many of our tests." DynamoRio Project
"Arm-based platforms provided by Works on Arm continues to support OCaml in processing 1000+ Aarch64 jobs per day in our Continuous integration cluster. This OCluster is used by OCaml developers to test their packages at scale to release quality software." Anil Madhavapeddy, OCaml Project
"Through the Works on Arm initiative the upstream CI fleet of the Python project has been expanded to provide coverage for the Arm architecture on various Linux Operating Systems. We have been able to catch early regressions leading to fixing not only bugs in the core Python language, but even in the Linux kernel and various toolchains, uncovered through Python's extensive test suite. This has helped establish Arm as one of the first-class architectures within the Python language ecosystem." Charalampos Stratakis, Python Language
"AlmaLinux made it a point to support and provide a first-class experience on Arm right out of the gate with our distribution. We've also made it a point to enable others to be able to use Arm as well. The ELRepo project is a project which builds various Linux kernels and modules for the Enterprise Linux ecosystem, and we enabled resources for them to be able to support Arm. We are sincerely thankful to Arm and their partners for all the support they've provided us, whether it be hardware or technical resources. Arm, and Arm developers have become a vital part of our community." Jack Aboutboul, Director and Community Leader, AlmaLinux
"The Node.js project provides prebuilt binaries of the open-source server-side JavaScript runtime on a variety of platforms. Our continuous integration builds and tests Arm v8 and Node.js on a regular basis including on pull requests opened by our contributors. The Works on Arm initiative provides us with the machines required for those builds on Arm. In addition, these systems support running many Jenkins jobs in parallel and we have used the Ampere Altra systems to support building and testing 32-bit armv7l distributions of Node.js in containers on those hosts. This has reduced our dependency on the less reliable single board computers including a number of Raspberry Pis which we were previously using for that work." NodeJS Project
"The Julia community has worked with Works on Arm to greatly improve its aarch64 platform support for Julia. This made it possible for the Arm platform to become a supported platform on Linux. Over the past year, our Arm binaries have seen over 100,000 downloads (only from, and support over 15,000 users." Viral Shah, Co-creator of Julia and CEO, Julia Computing
