The world runs on Open Source. From global commerce and finance to AI and critical infrastructure, the software that powers progress is increasingly built in the open. But Open Source in the enterprise isn’t just about technology—it’s about collaboration at scale. That’s why we’re excited to highlight the Certified Open Source Developer for Enterprise (CODE) certification, led by the TODO Group and Linux Foundation Training & Certification, with the Open Source Initiative (OSI) contributing as a supporting partner.
Whether you’re a developer, technologist, or organizational leader, CODE validates the skills enterprises need to harness Open Source effectively—not just technically, but responsibly and sustainably.
“25 years ago, Open Source was in a different place, and the needs of developers have changed. This certification helps both individual developers and the organizations that rely on the Open Source Definition to assure that Open Source continues providing critical value to the innovation engine upon which the global economy and human progress depend.” — Stefano Maffulli, Executive Director, Open Source Initiative
Why OSI supports CODE
As stewards of the Open Source Definition, OSI has long championed software freedom as a foundation for innovation. But Open Source software is more than a licensing model—it’s a shared responsibility. Developers are not only contributors; they’re gatekeepers of security, compliance, and sustainability.
The CODE certification bridges a crucial gap in the enterprise Open Source landscape. It trains certified professionals to apply Open Source practices in ways that align with enterprise risk management, strategic goals, and the values embedded in the Open Source community.
