Test the route before it matters
Check whether a proxy works, then inspect what the browser can still expose. Each tool reports evidence without promising anonymity or universal target access.
Proxy Checker
Queue up to 1,000 HTTP, HTTPS, SOCKS5, or SOCKS5H endpoints for progressive connectivity, target-response, cold response-time, exit-IP, and location evidence.

Open toolProxy checker evidence
Diagnose the stage, not just the badge
These focused guides explain transport behavior, error boundaries, cold response timing, and target responses from the same versioned checker methodology.
Proxy Checker Error Codes
Interpret proxy checker error codes for format, DNS, authentication, connection, TLS, timeout, response, and target failures without exposing credentials.
Method codes & stages
Read guideProxy Latency vs Speed
Learn what proxy response time measures, how exit and target timing differ, why latency is not throughput, and how to compare repeated proxy checks.
Method latency vs speed
Read guideHTTP, HTTPS & SOCKS5 Testing
Choose HTTP, HTTPS, SOCKS5, SOCKS5H, or bounded Auto proxy testing and understand TLS, target DNS, authentication, and unsupported UDP behavior.
Method http vs socks5
Read guideProxy Target Reachability
Understand how a proxy target check reads Google or Wikipedia response headers, what 2xx–5xx statuses mean, and why rejection is not proof of a block.
Method target reachability
Read guideEvidence library
Understand why browser routes disagree
These focused guides document methodology, interpretation boundaries, primary references, and a small anonymized route case series. They support the combined test without pretending one signal proves anonymity.
WebRTC Leak Test Guide
Read completed ICE candidates, baseline matches, same-network ambiguity, and timeout evidence without turning every address difference into a leak.

Read evidenceDNS Leak Test Guide
Understand tokenized resolver observations, public DNS, anycast, encrypted DNS, and why country mismatches remain review signals.

Read evidenceIPv6 Leak Test Guide
Compare both public address families and diagnose how an IPv4-only application route can leave browser IPv6 connectivity visible.

Read evidenceProxy vs VPN vs WARP Routing
Compare the common scope of HTTP proxies, SOCKS5 clients, full-device VPNs, and WARP across browser HTTP, WebRTC, DNS, IPv4, and IPv6.
