Check any proxy list in seconds

Bulk import

Paste from clipboard or drag in a file. Supports ip:port, user@pass:ip:port, domain:port:user:pass and more.

Thread & retry control

Set thread count and configure retries per protocol independently for accuracy vs. speed tradeoffs.

Protocol selection

Choose which protocols to check — HTTP, HTTPS, SOCKS4, SOCKS5. Fewer selections unlock higher thread counts.

Export with protocol prefix

Results export as protocol://ip:port with priority SOCKS5 -> SOCKS4 -> HTTP. Ready to use in any tool.

Anonymity detection

Uses a configurable judge URL that returns your real IP to detect if a proxy leaks your identity.

Blacklist filtering

Screen results against IP blacklists (single IPs or CIDR ranges). Lists reload automatically before each check.

Data capturing modes

Full data captures judge response, headers, and timings. Server mode parses response for server signatures.

Auto-updates

The app checks for new versions on launch and updates automatically — no manual reinstall needed.
