Introducing the OSSCAR Index

The OSSCAR Index addresses the challenge of ranking open-source projects by focusing on growth rather than size, using a transparent methodology based on new GitHub stars, unique contributors, and package downloads from npm, PyPI, and Cargo. Released quarterly, the index ranks projects within two divisions—Emerging and Scaling—based on their growth rate, enabling fair comparisons across different scales of organizations. The Q1 2026 results highlighted the significant growth of projects like Openclaw and the dominance of AI-related initiatives in the Emerging division. The methodology is designed to be global, avoiding biases towards Western-centric data sources, and encourages community feedback and contributions through its open-source platform. By providing visibility into rapidly growing projects, the OSSCAR Index aims to facilitate discovery, collaboration, and the overall health of the open-source ecosystem.
