Frequently asked questions
Is the bookmarklet free and safe?
Yes. It's a tiny open script that only reads the current domain and shows our public status result. It never touches your data, passwords or cookies.
It does nothing on some sites — why?
A few high-security websites (banks, government portals) block all external tools with strict security policies. On those sites, use our homepage or the status pages instead.
Does it work on mobile?
Bookmarklets are a desktop feature. On mobile, our site is fully responsive — just visit websitedownornot.com directly.
Prefer the full experience?
History graphs, outage board and alerts live on the site.
