When you enable "Developer mode" in the "Extensions" page of your browser, you can open the developer tools for the extension by clicking the "service worker" link, and from there select the "Network" tab, you will be able all the network requests made by the extension from within its service worker.

I just started using uBO Lite on Chrome. Brave is my daily driver and I just can't surf the web without an ad blocker anymore. I resisted it for years.

Thank you for all you do!

Thanks gorhill. Yes, this is true! Osprey only sends its stripped-down URLs to the services you turn on. Nothing more. It's as anonymous as it can be without using a VPN, afaik.

1) Osprey is just more protections built into one. It combines seven pre-existing safe browsing extensions you can already download into one lighter and better extension. All these extensions do is send the URL you visit to an API. That's what SmartScreen and Google SafeBrowsing do. 2) Read gorhill's comment. Checking network activity is easy, and checking every extension is always good.

Chrome and Edge contain just one single source of malicious website reports.

This addon uses multiple data sources.

As for logging: this submits URLs to various services. This is unlike Google Safe Browsing, which has a "periodically sync an offline database" setting (but will also send URLs to Google by default).

On 2, it appears to be open source so you could look and see if/what it logs.

I seems to send all urls you visit to Microsoft, Symantec, Emisoft, Webshield, Norton, Gdata Security, and/or BitDefender, depending on your settings. And of course, those URLs can be changed on the next update.

This is true, and they do. I'm replacing Comodo's Valkyrie API with Symantec's Browser Protection API for performance reasons. But, no data is logged, and only the minimum amount of data is sent to each provider.
