What is the DriftScore and how is it calculated?

Answer

The DriftScore is a metric from 0–100 that represents how far behind your codebase is relative to current stable ecosystem baselines. Lower scores mean a healthier upgrade posture — 0 means no drift (fully current) and 100 means maximum drift. Higher is worse. It's calculated from four weighted components: Runtime (Node.js/.NET version lag), Frameworks (major version distance for React, Next.js, etc.), Dependencies (age distribution across all deps), and EOL Risk (proximity to end-of-life dates).
