Checking what data is being sent over the network

How can I check and see what is being replicated to the client? I’m not really talking about remote events, but moreso instance properties and attributes. Is there a debug thing I can use to see this or a plugin?

In studio, whenever you are playtesting something you should be able to switch between client and server. The explorer and the property windows update according to whether you are viewing the client or the server, so you should be able to use them.
