Is Website SEO Checker safe?

Clean risk

Website SEO Checker sends the active tab URL to Sitechecker API endpoints when you open its popup.

When you open the extension popup, Website SEO Checker reads the current tab's URL and uses it to request SEO checks from Sitechecker. The URL is embedded in requests to Sitechecker's API so the service can analyze the page.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data

Destinations our analysis observed SiteChecker.pro contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
