Whale Config Checker

Whale Config Checker reads proxy config links the way an engineer reads a blueprint — and tells you whether they actually work.

Paste or scan a VLESS, VMess, Trojan, or Shadowsocks link and Whale decodes every field on your device: protocol, transport, security, Reality settings, SNI, UUID, and more. Built-in health checks flag the things that quietly compromise a connection — disabled certificate validation, a missing Reality key, an unencrypted transport, an odd port — and point to the exact parameter responsible.

Want to know if a config is any good? Test it. Whale's diagnostics service dials the configuration and reports back whether it connects, its latency, real download and upload throughput, and a full profile of the exit: country, city, network operator, whether it's a datacenter or flagged address, and a risk score for the far end.

The Origin tab turns the same forensic lens on your own connection. See your public IP, location, and operator; whether you're already behind a proxy; a quick speed check; and which DNS resolvers actually handle your lookups.

What Whale is not
Whale is an inspector and tester. It builds no tunnel, installs no network extension, and never routes or intercepts your device's traffic. Config links are parsed entirely on your device; only a link you choose to test is ever sent anywhere, and even then it is our service that connects to the server, never your phone.

What you can do
• Decode VLESS, VMess, Trojan, and Shadowsocks links on your device
• Read health checks that flag risky settings by the exact field
• Test reachability, latency, and download / upload speed
• See exit-IP intelligence: country, city, operator, datacenter / risk
• Profile your own connection with Origin — IP, speed, and DNS resolvers
• Scan and generate QR codes
• Save configs and keep every test result in your Library

With a one-time Pro unlock
• Test many configs at once, in bulk
• Compare two configs side by side, field by field
• Organize your Library with folders and tags
• Export and back up your entire Library

Privacy
No accounts. No sign-in. Parsing happens on your device. When you test a config, only that link is sent to our diagnostics service to run the measurement. See our Privacy Policy for the full picture.

Whale is free to inspect, test, and profile your connection. A one-time Pro unlock adds bulk testing, side-by-side compare, folders and tags, and library backup — no subscription.
