It's pretty simple
A proxy is an intermediate server that acts as an intermediary between the user and the resource that is being queried. The server itself can be located in any part of the world. And its use is set on the user's computer and all traffic, whether it is a request for a site or a connection in online games, will go through a proxy. Thus, instead of your IP, you will use the IP of the server. But free proxies can't guarantee anonymity, unlike private ones.
What is the difference between VPN?
A VPN is a virtual network that encrypts all data that passes through it. Unlike a proxy, a VPN will not only hide the IP, but also make the history of all outgoing traffic invisible
The advantages of proxies:
- hide the IP
- access to sites with geographical restrictions
- availability (there are many proxy servers)
- sometimes you can use a proxy to increase the connection speed
Disadvantages of proxy:
- no traffic encryption
VPN pros:
- fully encrypted connection
- hide the IP
Disadvantages of VPN:
- free VPN-work poorly and slowly
- paid VPNs are quite expensive
What's better? it all depends on your specific goal. For the simplest tasks, or for one-time use, you can use free proxies. And for comfortable and anonymous work - private
