Facebook Open Source is an initiative by Meta (formerly Facebook) that focuses on sharing the company's innovative technologies with the broader community to foster collaboration and collective improvement. The platform offers a wide range of open-source projects across various domains, including web development, mobile applications, data infrastructure, and artificial intelligence. By open-sourcing its technologies, such as React, PyTorch, and GraphQL, Facebook Open Source encourages developers to contribute to and benefit from the community-driven advancements. The official website, https://opensource.fb.com/, serves as a central hub for discovering these projects, accessing documentation, and contributing to or collaborating on open-source initiatives.
