How to set up a proxy or VPN only for certain sites?

Question

VPN

I want to set up a VPN or proxy only for certain sites, how do I do it?
Maybe in hosts somehow register the IP of some server through which to relay sites. I can buy for this some server somewhere.
Will it work if you add vk.com to CloudFlare to your account and change the direction yourself so that when you access vk.com, it turns to CloudFlare?

Answer 1

frigate extension . It downloads sites from the list of Roskomnadzor through a proxy, plus you can add your sites to your personal list in the settings. All other sites work directly. The most convenient of what I used.
Plus, as a bonus, with the extension installed, you can go to .onion sites from TOR (the same filibust, for example, without books blocked by copyright)

Answer 2

FoxyProxy
