Leaderboard
Every publicly analyzed repository (894 total), ranked by codebase health score - dead code, complexity, test file ratio, duplication, and file size.
See what breaks first
On expressjs/express, changing eb9df264-6bc3-46e3-b9db-f9bf0a63bdfa/index.js affects 109 other files - 96 directly, 13 transitively.
That's ArchSetu's blast-radius graph, traced automatically for every file in every repo it scans - not a health score, an actual dependency trace. Real result, computed live, not a mockup.
Open the Change Impact graphDead code is attack surface
Unreachable code still ships in your bundle. It can hide a forgotten auth check or a deprecated endpoint nobody is patching.
Complexity hides bugs from review
More branches means more edge cases a reviewer can miss - high-complexity functions are where vulnerabilities go unnoticed the longest.
Undeclared imports are supply-chain risk
A package imported but never declared can silently disappear or get typosquatted - see the Dependencies tab on any report.
