title: "Introducing the OSSCAR Index"
description: "Supabase has launched the OSSCAR Index, a quarterly ranking of fastest-growing open source organizations, with the site, data, and scoring code released as open source. It addresses the limits of rankings based on accumulated stars, downloads, or contributors by measuring community growth within two divisions: Emerging organizations below 1,000 GitHub stars at quarter-start and Scaling organizations at or above that threshold. Scores combine normalized net new stars, unique contributors, and npm, PyPI, and Cargo downloads using an L² norm, with minimum thresholds and no penalty for missing or declining signals. The Q1 2026 edition identifies Openclaw as a breakout project, places AI-agent projects prominently in Emerging, and reports global representation; quarterly updates, expanded package coverage, an RFC process, and historical rankings are planned."

# Introducing the OSSCAR Index

**Type:** Announcement

## Summary

Supabase has launched the OSSCAR Index, a quarterly ranking of fastest-growing open source organizations, with the site, data, and scoring code released as open source. It addresses the limits of rankings based on accumulated stars, downloads, or contributors by measuring community growth within two divisions: Emerging organizations below 1,000 GitHub stars at quarter-start and Scaling organizations at or above that threshold. Scores combine normalized net new stars, unique contributors, and npm, PyPI, and Cargo downloads using an L² norm, with minimum thresholds and no penalty for missing or declining signals. The Q1 2026 edition identifies Openclaw as a breakout project, places AI-agent projects prominently in Emerging, and reports global representation; quarterly updates, expanded package coverage, an RFC process, and historical rankings are planned.

## Context

The index responds to the lack of a ranking focused on current open source growth. Existing lists commonly rank raw totals such as stars, downloads, and contributors, which reflect accumulated size rather than which projects are growing fastest.

## Approach / What changed

OSSCAR ranks GitHub organizations in two divisions based on quarter-start star counts. It normalizes net new stars, unique contributors, and package downloads from npm, PyPI, and Cargo within each division, then combines the scores with an L² norm. Minimum thresholds, division locking, and rules for missing or declining signals are used to shape the ranking.

## Takeaways

- The site, data pipeline, and scoring code are open source, with a transparent and reproducible methodology that can be reviewed or changed through issues and pull requests.
- Division membership is fixed at the start of each quarter: organizations with fewer than 1,000 stars enter Emerging, while those with at least 1,000 enter Scaling.
- Openclaw finished Q1 2026 with 365,000 stars, 1,383 contributors, and 16.7 million package downloads after starting the quarter with 29 contributors and no package downloads.
