Test any proxy in seconds with our free online proxy checker. Verify IP address, anonymity level, latency, and protocol support — no signup needed. Supports HTTP, HTTPS, SOCKS4, SOCKS5, and mobile proxies.
Knowing whether a proxy is working before you use it is non-negotiable. A bad proxy wastes requests, triggers bans, and — worst of all — leaks your real IP. Our free proxy checker tool tests any proxy in seconds and gives you the full picture: working or not, what IP it returns, how anonymous it is, and how fast it responds.
A proxy checker (also called a proxy tester) is a tool that sends a test request through your proxy and analyzes the response. It tells you:
Without a proxy checker, you're flying blind. A proxy that appears to be "working" in your network config might still be forwarding your real IP in headers — a silent, dangerous leak.

No account required. Paste any proxy in host:port or host:port:user:pass format and get instant results.
The most important thing a proxy tester reveals is the anonymity level. There are three tiers:
The server cannot detect you're using a proxy. Your real IP is hidden. No X-Forwarded-For, Via, or Proxy-Connection headers are sent. The target site sees the proxy IP as a normal visitor.
Best for: scraping, multi-account management, avoiding bot detection.
The server knows a proxy is in use (via Via or Proxy-Connection headers) but cannot see your real IP. Some sites block anonymous proxies outright.
Best for: general privacy, bypassing geo-restrictions when detection doesn't matter.
The server sees both the proxy IP and your real IP (via X-Forwarded-For: your.real.ip). These proxies provide zero anonymity and should never be used for anything privacy-sensitive.
Best for: caching and network optimization only — not for privacy.
| Anonymity Level | Proxy IP Visible | Real IP Visible | Headers Leaked | |---|---|---|---| | Elite (Level 1) | ✓ | ✗ | None | | Anonymous (Level 2) | ✓ | ✗ | Via, Proxy-Connection | | Transparent (Level 3) | ✓ | ✓ | X-Forwarded-For with your real IP |
Step 1 — Format your proxy
Paste in one of these formats:
Step 2 — Choose test target (optional)
The default test target is a neutral IP detection endpoint. You can change it to test against a specific site (e.g., a streaming service or marketplace).
Step 3 — Read the results
| Result Field | What It Tells You | |---|---| | Status | Working / Dead / Timeout | | Returned IP | The IP the proxy presents to the world | | Real IP Leak | Your real IP if found in response headers | | Anonymity | Elite / Anonymous / Transparent | | Latency (ms) | Round-trip time through the proxy | | Protocol | Detected proxy protocol | | Country | Geolocation of the proxy exit IP |
A proxy checker gives you data — but you also need to know what "good" looks like:
Latency
| Latency | Quality | Use case | |---|---|---| | < 200ms | Excellent | Real-time scraping, ad verification | | 200–500ms | Good | General scraping, automation | | 500–1000ms | Acceptable | Non-time-sensitive tasks | | > 1000ms | Poor | Avoid for most use cases |
Anonymity: For anything beyond simple geo-unblocking, use Elite only.
IP rotation: A good proxy isn't just about the current check — it should rotate. Static proxies that never change IPs get blocked faster. Rotating mobile proxies maintain fresh exit IPs automatically.
IP quality: The IP should not appear on public blocklists (Spamhaus, AbuseIPDB). Our proxy checker cross-references the exit IP against common blocklists.
If you collected a list of free HTTP proxies from the internet, you'll find that most fail the checker within hours:
The checker will expose all of these. If you're seeing mostly red (dead), transparent anonymity, or 3000ms+ latency — it's time to upgrade to a real proxy.
