Batch-check HTTP/SOCKS5 proxies: availability, latency and real exit IP through an actual tunnel.
Quick answer
Paste up to 20 proxies, one per line — the tool opens a TCP connection, establishes a tunnel (CONNECT or SOCKS5) and makes a real request through the proxy, returning liveness, latency and the exit IP.
Do not paste third-party credentials on a hunch — requests originate from our servers. Limit: 20 proxies per run.
Proxies are a working tool for media buyers and scraping specialists, but public and even paid lists die fast: half the addresses may be down or egress from an unexpected country. Running traffic or farming accounts through an untested proxy is a straight path to bans.
Unlike checkers that merely ping a port, this tool performs a real run: TCP connection → handshake (CONNECT for HTTP, the 0x05 greeting for SOCKS5) → an actual GET request through the tunnel. For a live proxy you see the real exit IP — the address a target site will see — and the full chain latency.
What the checker does and does not do: checks run from Cloudflare edge servers over raw TCP sockets. The anonymity grade by headers (transparent/anonymous/elite) is not measured in this version — that requires an HTTPS target and the platform cannot do TLS inside the tunnel. Instead you get the honest exit IP to compare against the vendor's claimed geo.
