Tell me a service to change the appearance of sites?

Question

css

Hello!

For a long time, somehow on Habré, information about the service of changing the appearance of the site ran through. I searched for three days, but did not find it. Google doesn't give anything either. Looks like I didn't remember the wording. The essence of the service is that any page of any site is taken, styles, pictures, and so on are changed. Then a link is given to a page with all the changes.

Please help if anyone remembers.
Thanks in advance.
