To Our Members and Community,

We are pleased to share the 2025 Linux Foundation Annual Report, “Innovation in the Open,” which reflects on a defining year for open source and the LF.

This report captures the momentum you created: major project milestones, deepened collaboration across ecosystems, new foundation launches, record participation at events worldwide, and the continued maturation of our security, training, research, and community programs.

Thank you for being part of this community. The scale and impact of what we accomplished in 2025 reflect the strength of our members, contributors, maintainers, and partners who continue to build the future together, collaborating in the open.
