Open-Source Sustainability

Open Source
The funding community that pays for the maintenance and health of open-source software itself: maintainer salaries, project stewardship, security work, and fiscal hosting. Capital moves through project-steward foundations (Apache, Linux Foundation, PHP, Perl, FreeBSD, Drupal Association and peers), corporate FOSS funds (GitHub Secure Open Source Fund, Microsoft FOSS Fund, Spotify FOSS Fund, Google Summer of Code, Meta Open Source), philanthropic programs (Sloan and Ford digital-infrastructure funding, CZI Essential Open Source Software, Mozilla MOSS), and dedicated funds and fiscal hosts such as Open Source Collective, FLOSS/fund, and the Open Source Endowment.
