The Scoreboard

Live Grasp Scores for repositories most engineers would recognize, rescanned on a schedule from each repository's own git metadata. The score estimates how much of the codebase someone still active genuinely understands. Every number links to its full scan report, and the method behind it is published in full.

These are touch-weighted free scans over each repository's recent history, the same scan anyone can run from the homepage. They are comparable with each other, not with the line-weighted deep scans in the 2026 benchmark report. Public-repo caveat: "inactive" includes drive-by contributors, which overstates attrition relative to a company repository with a real roster.

Your repo is not here? Scan it yourself, free: sixty seconds, no signup.
