Is URL Kürzer safe?

Clean risk

URL Kürzer sends the active or selected page URL to a URL-shortening service when you create a short link.

When you use the popup or context-menu action, URL Kürzer reads the current tab URL or selected page URL and submits it to the configured shortening service. The request goes to the service's /ext endpoint with the page URL, extension version, no-referrer setting, and optionally an account key if the user configured one.

Shared hosts - 9 hostnames

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.
