Matrixshrink runs on your own machine — the client starts it, so there is no endpoint to ping. 267 installs a week from npm. Last commit 2 Nov 2026.
Finds redundant CI matrix combinations from run history and coverage overlap.
Today is the operative word: we check Matrixshrink every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
