The infrastructure is free — the maintenance is not
Open-source powers 90% of the modern web. Every startup, enterprise, and government runs on it. Yet most maintainers work nights and weekends, unpaid.
Funding directly reduces burnout
Financial support lets maintainers dedicate real time to their projects — fixing bugs faster, shipping security patches, and responding to issues.
Healthy projects mean a healthier internet
Abandoned packages create security vulnerabilities. Funded maintainers mean the tools you depend on keep getting better, not becoming liabilities.

Developers love OSF
Maintainers, contributors, and supporters who have already made the move.
“I've maintained my library for six years without a cent. Within three months on OSF I had 40 sponsors covering my hosting costs and then some.”
“Finally a place that feels built for developers, not marketers. The project pages are clean and the funding flow took me under five minutes to set up.”
“Our company now funds 12 open-source projects through OSF. It's the cleanest way to give back without a procurement headache.”
“The discovery is excellent. I found three libraries I depend on every day that I had no idea accepted funding. Fixed that immediately.”
