關於 Proxy 工具
檢查 HTTP、HTTPS 或 SOCKS5 Proxy 連線
Proxy failures can happen during DNS resolution, authentication, connection setup, TLS negotiation, or the upstream request. A successful result is valid only for the supplied proxy, target, and time; it is not a general guarantee of anonymity, privacy, or future availability.
點樣用呢個開發者工具
- Enter one authorized proxy per line and confirm each scheme, host, port, and authentication format.
- Choose a target URL that you are authorized to request. Duplicate entries are removed and the batch is bounded to 100 entries.
- Review reachability, authentication, response status, latency, and any observed exit or error details for each entry.
- Remove stale credentials and repeat unstable checks at another time. Respect both the proxy provider's and target site's rate limits.
私隱同資料處理
Proxy addresses, optional usernames and passwords, target URLs, and check settings are sent to this site's server because the request is executed remotely. They are used to perform the requested check and are not intentionally stored as a user profile. Never submit credentials you are not authorized to test, and avoid sharing result screenshots that contain secrets.

常見問題
Does an open proxy port mean the proxy works?
No. The proxy may still fail authentication, TLS negotiation, DNS resolution, or the upstream request. Review the failure stage and target response instead of relying on the port alone.
How many proxies can I test at once?
The tool accepts up to 100 unique entries per batch and uses bounded concurrency so results remain readable and requests remain controlled.
Can I test any proxy or website?
Only test infrastructure and destinations you are authorized to use. Follow provider terms, avoid abusive rates, and do not use the checker to bypass access controls or restrictions.
