I want to see who is accessing which sites on my home network. Is this possible? If yes, with which tool(s)?
There are many ways to do this. One of the easiest is Pi-hole
While it's "main" function is to block ads and it has a nice Web interface that you can view a lot of network traffic. This will give you some idea of what is available via the Web interface.
I'd recommend using a Raspberry Pi or similar SBC. You can also use a desktop or etc... to run it.
Thanks, I'll check it out.
Some home routers are capable of http level logging. If not, it is possible to set up home proxy server and parse its logs.
