There have been numerous other efforts to formalize open source project financing in the past five years alone, including dedicated FOSS funds from Indeed and Salesforce, a tacit acknowledgment that critical components of the tech stack are crying out for support.

One of the biggest efforts of late, however, hails from developer tooling unicorn Sentry, which itself has been donating to open source projects for many years. In 2021, Sentry adopted a more systematic program with firmer and more transparent commitments, and last month the company officially launched the Open Source Pledge to encourage other companies to get involved — either by donating directly through platforms such as GitHub Sponsors or Thanks.dev, or indirectly via foundations.
