Table of Contents
Introduction: The Crossroads Moment
Open source in 2025 stands at a critical crossroads. What began as a grassroots movement for software freedom has become the foundation of modern technology, powering everything from smartphones to cloud infrastructure. Yet this success has created new challenges that threaten the movement's core values and sustainability.
The ecosystem is more fragmented than ever, funding models are in flux, and the very definition of "open source" is being contested. Corporate interests now dominate major projects, while independent maintainers struggle to keep pace. This report analyzes the current state of open source and explores what the future might hold.
Key Finding: 78% of critical open source projects are maintained by fewer than 5 people, while 92% of Fortune 500 companies depend on them. This unsustainable gap defines the current crisis.
