Online Proxy Tester: HTTP proxy online test & SOCKS proxy online test
Use this page as an online proxy tester: run an HTTP proxy online test or a SOCKS proxy online test (SOCKS4/SOCKS5) through a public probe URL you choose. Test up to 20 proxy lines per run and see latency, bytes, and optional exit IP.
Supported formats
You can paste these shapes into the proxy list. HTTP shorthand is normalized on the server.
HTTP proxy
- user:pass@proxy.example.com:8080
- proxy.example.com:8080 :user:pass
- http://user:pass@proxy.example.com:8080
SOCKS proxy
- socks5://user:pass@socks.example.com:1080
- socks4://user:pass@socks.example.com:1080
SOCKS URLs must include the scheme (socks4:// or socks5://) and slashes.
Must be http or https. Only common web ports are allowed. Hostname must resolve to a public address.
Maximum 20 proxy URLs per run. Credentials are used only for this test and are not stored.
Privacy note
Proxy credentials, proxy URLs, and the probe URL are sent to our API only for this connectivity test and are not stored.
How it works
- Paste one proxy URL per line. This tool supports an HTTP proxy online test (http/https upstream) and a SOCKS proxy online test (socks4/socks5).
- Set the probe URL (https recommended). The default loads a small public asset.
- Click Test proxies. Each row updates when its test finishes.
- Use Stop to cancel tests that have not completed yet.
- Private or loopback proxy hosts are rejected by the server.
