Open source software is integral to modern applications, with about 90% of companies utilizing such projects, as highlighted by FusionAuth's commitment to open source through their Apache 2.0 licensed libraries and SDKs, and the widely-used FusionAuth Community. Despite their importance, many open source projects face funding challenges, prompting FusionAuth to sponsor several, including Git, Passport.js, and NextAuth.js, to support their development and ensure they continue to benefit developers. FusionAuth emphasizes open source's role in enhancing developer experiences across standalone and commercial projects and is actively seeking to sponsor additional open-source projects, particularly those related to authentication and identity.
