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.

The Funding Crisis: Reality Check

The Numbers Don't Lie

The funding gap in open source has reached crisis proportions. Despite generating trillions in economic value, most projects operate on shoestring budgets or volunteer labor.

Funding Realities

  • 85% of projects have no dedicated funding
  • $0-500/month typical maintainer income
  • 70% of maintainers have other full-time jobs
  • 40% consider quitting due to burnout
  • 92% of critical infrastructure underfunded
  • $3.7M average funding needed per major project

Economic Impact

  • $8.8 trillion global economic contribution
  • 96% of Fortune 500 use open source
  • 30 million developers contribute
  • 100 million+ open source projects
  • 0.1% of value captured by maintainers
  • 1000:1 value extraction ratio

The Burnout Epidemic

Maintainer burnout has become the single greatest threat to open source sustainability. The emotional and financial toll of maintaining critical infrastructure for free is taking its toll.

Burnout Statistics

Workload

Average maintainer spends 20+ hours/week on unpaid work, handling security issues, bug reports, and community management.

Mental Health

67% report anxiety/depression, 45% experience regular harassment, and 30% have received death threats.

Abandonment

40% of maintainers have abandoned projects, creating security risks for millions of users.
