iplocate/free-proxy-list ? reverse-engineered prompt

Build me a simple site that shows a free, updated proxy list people can browse and copy from.

It should have a main page with the latest working proxies, plus clear sections for HTTP, HTTPS, SOCKS4, and SOCKS5, and country based lists too. Make it easy to filter or switch between all proxies, protocol types, and countries, and let users copy a proxy in the usual host:port format. I also want a small help section that explains how to test whether a proxy works, using the example IP check endpoint from the project.

Keep the design clean and fast, with a search box, an easy to read table, and a way to show that the proxies are tested every 30 minutes and have no duplicates. If it makes sense, add a simple note about anonymity and that these are working public proxies. Look up current docs online if you need to.
