Is Vercel safe?
Vercel lets feedback frames use the extension to fetch arbitrary URLs and receive captured tab screenshots.
In feedback frames on vercel.live and matching vercel.sh deployments, page messages can ask the background script to fetch caller-supplied URLs under the extension's <all_urls> permission. Those frames can also authorize themselves through their own validation endpoint and then receive a visible-tab screenshot as a PNG data URI.
Part of this rating comes from analysis signals we haven't published as detailed findings yet.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 2 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.

What it can do
Permissions this extension asks for, as declared in version 1.4.0. Asking for a permission is not a finding on its own - it is what the extension can do if it chooses to.

Where it sends data
Destinations our analysis observed Vercel 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.
