What is a SOCKS4 proxy?
SOCKS4 is a lightweight tunnelling protocol that relays raw TCP connections. It carries no authentication and resolves hostnames on the client side, which makes it fast and simple but less capable than SOCKS5.
SOCKS4 is a fallback for legacy tooling that predates SOCKS5. If your client supports SOCKS5, prefer it — you get UDP support and remote DNS resolution for the same effort.

Frequently asked questions
Are these free proxies safe to use?
Free public proxies are shared and run by unknown operators, so never send passwords, tokens or personal data through them. Use them for testing, scraping public pages and automation — not sensitive traffic.
How often is the proxy list updated?
Every proxy is re-checked and the list republished every 30 minutes. Each JSON record carries a lastChecked timestamp and a latency value so you can drop stale or slow entries yourself.
What does 'verified' actually mean here?
Each entry completed a protocol-correct handshake and relayed a real request end to end before publication. Entries that only answered a TCP connect are not published.
Why do some proxies stop working within minutes?
Free proxies are volatile by nature — they appear and disappear constantly. That is exactly why the list is re-checked every 30 minutes and sorted fastest-first. Always loop to the next entry on failure.
Free public proxies are shared and operated by unknown parties. Never send passwords, tokens or personal data through them. Follow the GitHub Acceptable Use Policies: no spam, no attacks, no bypassing access controls, no scraping against site policies.
