Open Mainframe Project 2023 Annual Report – Milestones, Stats & More

By | February 20, 2024February 23rd, 2024

As we reflected on our growth and achievements last year, we’re excited to see how open source continues to make a huge impact on the mainframe industry. We had more than 2,100 contributors and 95,000 commits to Open Mainframe Project hosted projects this year. Zowe continues to gain adoption with nearly 40% of mainframe customers leveraging Zowe, according to the Arcati Mainframe Yearbook. Additionally, we welcomed Galasa as a new project, which signals that there are more opportunities for open source in the mainframe ecosystem.

One question that many mainframe customers and vendors have is how our projects are valuable to their bottom line. The answer is pre-competitive, leveraged development. I see this in other horizontal and vertical markets with huge success stories. Automotive Grade Linux formed to bring together automakers and their supply chain on a common platform. Academy Software Foundation hosts the common projects that all the major studios leverage for visual effects in the movies. The list goes on and on, and it shows that when an industry can work together to build the common pieces of their software stack that aren’t differentiating, the result is higher quality, lower cost, and more secure.

Look for more to come in 2024 as this theme is further explored. I hope you enjoy the 2023 Open Mainframe Project Annual Report to see the continued progress the Open Mainframe Project is making to ensure a sustainable future for mainframe.
