Snapdiff runs on your own machine — the client starts it, so there is no endpoint to ping. 74 installs a week from npm. Last commit 11 Sep 2026.
Visual-diff & change-detection tools that catch agentic UI drift for coding agents.
Nothing serious here today
Today is the operative word: we check Snapdiff every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
