Is Rebrandly | URL shortener safe?

Low risk

Rebrandly sends the active tab URL and title to api.rebrandly.com when you create a short link.

When you use the browser action to shorten a page, the extension reads the active tab's URL, title, and favicon, then posts the destination URL and optional title to Rebrandly's link API using the stored Rebrandly token. It also exposes a localhost-only message bridge that accepts clipboard read and write requests from http://localhost pages.

Shared hosts - 21 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.
