WhoFundsOSS: A public ledger of open-source funding
A monthly ranking of companies based on publicly disclosed open-source pledges, donations, and sponsorship amounts.
- For
- Open-source maintainers and ecosystem researchers
- Worth noticing
- Private GitHub sponsorship tiers remain uncounted; cumulative gifts stay separate from yearly pledges.
Field notes
The methodology names four inputs: Open Collective donations, Open Source Pledge commitments, visible GitHub sponsorship tiers, and figures companies publish about their own programs. The page says Open Collective totals are often cumulative, while Pledge figures are yearly; it also leaves private sponsorship amounts out rather than estimating them. A monthly comparison depends on a second snapshot, so the current ranking is not presented as a complete account of all funding.
