Is EuroSaver - Amazon Europe Price Comparison safe?

Low risk

EuroSaver lets eurosaver.net request Amazon product pages and sends extracted product details back over a WebSocket.

By default, EuroSaver opens a WebSocket connection to realtime.eurosaver.net and authenticates with a stable generated user ID. The server can ask the extension to fetch specific Amazon product pages under its Amazon site permissions, and the extension returns extracted fields such as price, product name, seller/store, image, shipping cost, and currency.

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.
