How to change/append URL in browser when using Open Server?

Question

local server

I use Open Server to develop the site.
The problem is that when viewing the LOCAL version of the site, the url in the browser is displayed in the same way as in online.
Example. There is a site sitename.ru
When I look at it locally, the url in the browser looks like sitename.ru
When I look online also sitename.ru
And it's not clear whether this site is local or online.
How to make the url look like this when viewing the local version in the browser:
localhost/sitename.ru
or at least somehow differ from the online address in order to understand which version you see in front of you and not get confused.

Answer 1

rename the folder and restart the server and look at the settings of the site itself, perhaps the url is registered there.
