There are a bunch of websites that claim to list hundreds of free public proxy servers.
And you will find some more if you just Google "free public proxies."
Having gone down that road earlier in our careers, we found that if you want to use it in a web scraping project reliably, you will need to be able to be confident of your proxies in the following areas.
Availability: Public proxy servers keep shutting down quite often, so you need to develop algorithms to weed them off and update them almost every few minutes.
Reliability: Public proxy servers are used by thousands of developers and so slow down almost minutes after they are detected and become unresponsive
Speed: Public proxy servers are just individuals browsing, and you mostly don't have any control over their connection plans
Security: It's difficult to certain about whether the individual whose device is used as a proxy has given consent to use their bandwidth for free. In fact, in many cases, its hackers who have taken control of their connections and they might as quickly be logging all the information you send.
Private proxy servers, when rotated well, are reliable, with high-speed returns and much more available.
It's difficult to imagine writing serious web scraping without a private, rotating proxy service.
We developed one to help resolve all the headaches we faced with public proxies.
