We scan GitHub commit history continuously — no surveys, no download counts. See exactly which packages developers are dropping, what they're switching to, and which tool combinations survive production. Ground truth from 4,535 real repositories.
Get API AccessPackage-level market research derived from actual code changes — not download counts, not surveys, not analyst estimates. When a developer removes one package and adds another in the same commit, that's a migration event. Across 422 of those events, a ground-truth picture of where the market is moving emerges.
See how many repos migrated FROM your competitor TO you — or the other way around. Real numbers, not surveys.
