TSight
Reads a TypeScript codebase and reports what’s actually there — hotspots, blast radius, bus factor, duplication — from AST and git history, not estimation. No model in the loop. No code leaves the machine. Every number is verifiable against the repo you point it at.
I built it because the things I care about inside a company — whether the team can operate without the original engineer — are the same things I wanted to measure outside of one.
