how can i have many web pages on a single web page?

I use several pages once a day and so I would like to stitch them or put
them together under one "roof" as such. I thought that have them all one
one web page would be perfect. But how do I go about doing this? Is there
a browser extension that can do this perhaps? For example, I would like a
single web page (tab in my browser) that contains the feeds/or pages from
Google Analytics, Klout Dashboard, Scoop.it etc.
