SyteCheck runs on your own machine — the client starts it, so there is no endpoint to ping. 354 installs a week from npm. Last commit 10 Sep 2026.
Scan a website for SEO, accessibility, performance and security issues, and read the report.
Today is the operative word: we check SyteCheck every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
