GitHub’s top project this year, by contributor count, was Microsoft’s Visual Studio Code (with 19,000 contributors), followed by Facebook’s React Native (10,000), TensorFlow (9,300) and Angular CLI (8,800) — as well as Angular (7,600) — and the open source documentation for Microsoft Azure (7,800).
Top open source projects
VS Code, React, and Tensorflow once again top the list of open source projects by contributor count. New to the list are projects that manage containerized applications, share Azure documentation, and consolidate TypeScript type definitions: Kubernetes, Azure Docs, and DefinitelyTyped.
1 Microsoft/vscode 19K
2 facebook/react-native 10K
