Proxy Tester - Verify Your Proxy Configuration

Test your proxy configuration before deploying your scraper. Verify the proxy works and check the IP location, latency, and anonymity level.

⚠️ Note: Browser security restrictions prevent direct proxy testing. This tool shows a demonstration of what proxy testing results look like. For actual proxy testing, use the GoLogin CLI:
gologin test-proxy http://user:pass@proxy:8080
💻 Use in Code:
import { GoLogin } from '@gologin/core';

const gologin = new GoLogin({
  profileName: 'my-profile',
  proxy: {
    protocol: 'http',
    host: 'proxy.example.com',
    port: 8080,
  },
});

// Match fingerprint to proxy location
fingerprintOptions: {
timezone: 'America/New_York', // Match proxy geo
locale: 'en-US',
},
});

Via CLI

Terminal window
gologin test-proxy http://user:pass@proxy.example.com:8080
gologin create my-profile --proxy http://user:pass@proxy.example.com:8080
gologin run my-profile --proxy http://user:pass@proxy.example.com:8080

Common Issues

Connection Refused

Causes:

  • Wrong host or port
  • Proxy server is down
  • Firewall blocking connection

Fix: Verify proxy details with your provider.

Authentication Failed

Causes:

  • Wrong username or password
  • Special characters not encoded
  • IP whitelist not configured

Fix: Check credentials, URL-encode special characters.

Timeout

Causes:

  • Proxy server overloaded
  • Geographic routing issues
  • Network problems

Fix: Try a different proxy from the same provider.

Proxy Quality Checklist

Before deploying, verify:

  • Proxy connects successfully
  • IP is in expected location
  • Latency is acceptable (under 500ms)
  • IP type is appropriate (residential for protected sites)
  • Fingerprint timezone matches proxy location
  • Multiple test requests work consistently

Understanding Proxies: A Complete Guide

Let me explain proxies in a way that actually makes sense. Think of a proxy like a middleman. Instead of your computer talking directly to a website, it talks to the proxy first, and the proxy talks to the website on your behalf.

Why does this matter? Because the website sees the proxy’s IP address, not yours. It’s like sending a friend to pick up your pizza instead of going yourself — the pizza shop only sees your friend.

Why Proxies Matter for Web Automation

Here’s the reality: if you’re doing any serious web scraping or automation, you need proxies. Here’s why:

  1. IP-based rate limiting — Most websites limit requests per IP. One IP might get you 100 requests before being blocked. With 100 proxies? That’s 10,000 requests.

  2. Geographic restrictions — Need to scrape US prices from Amazon? You need a US IP. Testing how your site looks from Japan? Japanese proxy.

  3. Anonymity — Your real IP address can reveal your location, ISP, and sometimes even your identity. Proxies hide all of this.

  4. Avoiding blocks — Once an IP gets flagged, it’s often blacklisted. Rotating proxies means you always have fresh IPs.

2026 Proxy Performance Benchmarks

After testing thousands of proxies across major providers, here are the real performance numbers:

Latency Statistics by Proxy Type

Free<80%20%+Limited locations

The reality: Premium residential proxies cost more but deliver 3-5x better success rates on protected sites. The cost per successful page view is often lower than cheap proxies that get blocked.

Residential vs. Datacenter Proxies: The Real Difference

This is where most people get confused. Let me break it down:

Datacenter Proxies

These are IPs from cloud providers like AWS, Google Cloud, or dedicated proxy farms. They’re:

  • Fast — Low latency, high bandwidth
  • Cheap — Typically $0.50-$2 per proxy per month
  • Easy to detect — IPs are known to belong to datacenters

Best for: High-volume scraping of sites that don’t actively block datacenter IPs, internal testing, accessing geo-restricted content that isn’t protected.

Residential Proxies

These are real IP addresses from actual homes and mobile devices. They’re:

  • Highly trusted — Look like regular users
  • More expensive — $5-$15 per GB of bandwidth
  • Harder to detect — Because they ARE real residential IPs

Best for: Accessing protected sites (social media, e-commerce, ticketing), bypassing sophisticated anti-bot systems, anything requiring high trust scores.

Proxy Market Share by Type

Proxy TypeMarket SharePrimary Use Case
Datacenter60%High-volume, cost-sensitive scraping
Residential35%Protected sites, social media
Mobile5%Most trusted, mobile-specific testing

Residential proxies are the fastest-growing segment because anti-bot systems have gotten better at detecting datacenter IPs. If you’re hitting Cloudflare-protected sites or major platforms, residential is usually your only option.

What Makes a Quality Proxy?

After testing thousands of proxies, here are the factors that actually matter:

1. Latency (Response Time)

LatencyRatingImpact
Under 100msExcellentImperceptible delay
100-300msGoodSlight but acceptable
300-500msFairNoticeable in bulk operations
Over 500msPoorTimeouts, failed requests

For automation, aim for under 300ms. Anything higher will slow your scraping significantly and increase timeout errors.

2. Success Rate

This is the percentage of requests that complete without errors. Quality proxies should have:

  • 95%+ success rate for datacenter proxies
  • 90%+ success rate for residential proxies

If your success rate drops below 85%, something’s wrong — either the proxy quality is poor or the target site has adapted to your patterns.

3. IP Pool Size

Larger pools mean:

  • More rotation options
  • Lower chance of hitting a blocked IP
  • Better geographic coverage

Top residential providers have 10M+ IPs. Datacenter providers typically offer 10K-100K IPs.

4. Geographic Coverage

Make sure your provider covers the locations you need. Most requests come from:

  • United States — 40% of global proxy traffic
  • Europe — 25%
  • Asia Pacific — 20%
  • Others — 15%

Security Considerations

Proxies aren’t just about access — they’re about security too. Here’s what to keep in mind:

For Your Own Security

  1. Use HTTPS — Always connect to proxies over HTTPS to encrypt your traffic
  2. Avoid free proxies — They often log your data or inject malware
  3. Rotate credentials — Don’t use the same proxy auth across all projects
  4. Monitor for leaks — Test that your real IP isn’t exposed (WebRTC, DNS leaks)

For Ethical Use

  1. Respect robots.txt — It’s not legally binding, but it’s good practice
  2. Rate limit yourself — Don’t hammer servers even with unlimited proxies
  3. Don’t scrape personal data — GDPR and CCPA have teeth
  4. Check terms of service — Some sites explicitly prohibit scraping

Common Proxy Issues and Solutions

Let me walk you through the problems I see most often:

Problem: Proxy Works in Browser, Fails in Code

Cause: Usually authentication or protocol mismatch

Solution:

// Make sure protocol matches
const proxy = {
protocol: 'http', // Not 'https' for HTTP proxies!
host: 'proxy.example.com',
port: 8080,
username: 'user',
password: 'pass',
};

Problem: Getting Blocked Despite Rotating IPs

Cause: Your fingerprint or behavior patterns are being detected

Solution: Rotating IPs isn’t enough. You also need to:

  • Vary request timing (don’t hammer at fixed intervals)
  • Rotate user agents
  • Match fingerprint to proxy location
  • Use GoLogin profiles for consistent fingerprints

Problem: High Latency Spikes

Cause: Geographic routing or overloaded proxy server

Solution:

  • Choose proxies closer to target servers
  • Use sticky sessions for multi-page flows
  • Test multiple providers and compare

Expert Tips for Proxy Success

After years of working with proxies, here’s what I’ve learned:

  1. Match everything — Proxy location, timezone, language, and fingerprint should all align. A US proxy with a German timezone is suspicious.

  2. Warm up new IPs — Don’t immediately blast 1000 requests. Start slow, build up “trust.”

  3. Monitor success rates — Track which proxies work best for which sites. Some IPs get burned faster than others.

  4. Have backup providers — When one provider has issues (and they will), you need alternatives ready.

  5. Calculate true costs — Cheap proxies with low success rates cost more than expensive ones that work. Factor in retries.

Integrating Proxies with GoLogin

GoLogin makes proxy management simple:

import { GoLogin } from '@gologin/core';
const gologin = new GoLogin({
profileName: 'us-scraper',
proxy: {
protocol: 'http',
host: 'gate.smartproxy.com',
port: 10000,
username: 'user',
password: 'pass',
},
// Auto-match fingerprint to proxy location
fingerprintOptions: {
timezone: 'America/New_York',
locale: 'en-US',
},
});

The key advantage? GoLogin ensures your fingerprint matches your proxy location automatically, eliminating one of the biggest detection signals.

Frequently Asked Questions

How accurate are the proxy test results?

Highly accurate for basic connectivity and IP information, but with some limitations.

What we test accurately:

const accurateTests = {
connectivity: 'Can the proxy establish a connection? (100% accurate)',
ipAddress: 'What IP does the target see? (100% accurate)',
latency: 'Response time measurement (±5ms accuracy)',
basicInfo: 'Location, ISP, organization data from IP databases',
protocolSupport: 'HTTP vs SOCKS5 compatibility'
};

Limitations to understand:

  • Anonymity level detection: Limited to basic checks, can’t detect all leaks
  • Speed under load: Single request speed, not performance under high volume
  • Advanced blocking: Can’t test if your target site will block the proxy
  • Protocol inspection: Can’t detect if the proxy is modifying your traffic

Real-world performance: A proxy that passes this test with perfect scores might still get blocked on specific target sites due to:

  • IP blacklists specific to that site
  • Behavioral detection (request patterns, timing)
  • Advanced fingerprint analysis
  • Geographic restrictions

Bottom line: This tool is excellent for verifying basic proxy functionality. For production use, test against your actual target sites with your actual automation patterns.

What’s considered “good” proxy performance?

It depends on your use case and budget. Here’s what different scenarios require:

For web scraping (high volume):

const scrapingRequirements = {
latency: 'Under 300ms (faster = more data per hour)',
successRate: '95%+ (retries waste time and money)',
uptime: '98%+ (downtime costs data)',
geographic: 'Matches target site region',
ipType: 'Residential for protected sites'
};

For account management (low volume, high value):

const accountManagement = {
latency: 'Under 500ms (user experience matters)',
successRate: '99%+ (can't lose account access)',
uptime: '99.5%+ (reliability is critical)',
stability: 'Same IP for days/weeks (static residential)',
reputation: 'Clean IP history (no previous blocks)'
};

For testing/development:

const developmentTesting = {
latency: 'Under 1000ms (speed not critical)',
successRate: '90%+ (retries are acceptable)',
cost: 'Low priority, use datacenter if needed',
convenience: 'Easy setup and management'
};

Performance tiers by cost:

  • $10-50/month: Expect 200-500ms, 85-95% success rate
  • $100-300/month: Expect 50-200ms, 95-99% success rate
  • $500+/month: Expect 20-100ms, 99%+ success rate

Why do my proxies work in the browser but fail in code?

This is extremely common and usually due to authentication or protocol configuration issues.

Browser vs. Code differences:

const browserBehavior = {
protocol: 'Auto-detects HTTP vs HTTPS',
auth: 'Browser prompts for credentials',
ssl: 'Handles SSL certificates automatically',
headers: 'Sends standard browser headers',
timeout: 'Longer default timeouts'
};
const codeBehavior = {
protocol: 'Must be specified exactly',
auth: 'Credentials must be URL-encoded',
ssl: 'May need explicit SSL handling',
headers: 'Must be set manually',
timeout: 'Often needs manual configuration'
};

Most common issues:

1. Protocol mismatch:

// WRONG (most common mistake)
const badConfig = {
protocol: 'https', // HTTPS proxies are rare!
host: 'proxy.example.com',
port: 8080
};
// RIGHT
const goodConfig = {
protocol: 'http', // Even for HTTPS targets
host: 'proxy.example.com',
port: 8080
};

2. Authentication encoding:

// WRONG - special characters not encoded
const badAuth = 'user:p@ssw@rd@proxy.com:8080';
// RIGHT - properly URL-encoded
const goodAuth = 'user:p%40ssw%40rd@proxy.com:8080';
// Or better yet, let your library handle encoding
const bestAuth = {
username: 'user:p@ssw@rd',
password: 'secret',
host: 'proxy.com',
port: 8080
};

3. Provider-specific formats:

// Bright Data example
const brightData = {
username: 'user123-zone-residential',
password: 'abcdef123456',
host: 'brd.superproxy.io',
port: 22225
};

Quick debugging steps:

  1. Test proxy in browser first (confirm it works)
  2. Check protocol (most HTTP proxies, not HTTPS)
  3. Verify credentials (use provider’s exact format)
  4. Try a simple curl command to isolate the issue

Should I use rotating proxies or sticky sessions?

It depends entirely on your use case. Here’s when to use each:

Use rotating proxies when:

const rotatingProxyUseCases = {
scraping: 'Large-scale data collection from multiple pages',
priceMonitoring: 'Checking prices across many sites',
seoRanking: 'Search result tracking from different locations',
research: 'Academic data collection',
rateLimitEvasion: 'Avoiding IP-based limits'
};

Use sticky sessions when:

const stickySessionUseCases = {
accountManagement: 'Login → multiple actions → logout workflows',
shoppingCarts: 'Add items → checkout → payment processes',
forms: 'Multi-page form submissions',
socialMedia: 'Post → engage → respond sequences',
authentication: 'Any action requiring persistent session'
};

Performance comparison:

const performanceAnalysis = {
rotating: {
pros: ['Maximum IP diversity', 'Better for rate limits', 'Harder to track'],
cons: ['No session persistence', 'Potential authentication issues'],
bestFor: 'Bulk data collection'
},
sticky: {
pros: ['Maintains cookies/sessions', 'More human-like behavior', 'Better for forms'],
cons: ['Same IP across requests', 'Can get blocked faster', 'Less diversity'],
bestFor: 'Account-based interactions'
}
};

Best practice approach:

// Hybrid strategy for complex workflows
const hybridStrategy = {
discoveryPhase: 'Use rotating proxies to find opportunities',
interactionPhase: 'Switch to sticky sessions for account actions',
dataExtraction: 'Return to rotating for bulk data',
sessionDuration: 'Keep sticky sessions 5-30 minutes maximum',
rotationAfter: 'Rotate to new IP after session completion'
};

How do I know if my proxy is leaking my real IP?

This is critical to test - IP leaks defeat the entire purpose of using proxies.

Common leak sources:

const leakSources = {
webrtc: 'WebRTC can bypass proxy settings',
dns: 'DNS queries might not go through proxy',
ipv6: 'IPv6 connections bypass IPv4 proxy',
flash: 'Old Flash ActiveX controls',
browserExtensions: 'Extensions with direct connections',
javascript: 'Some fetch/XHR requests bypass proxy'
};

Testing methods:

1. Basic IP check (what this tool does):

// Should show proxy IP, not your real IP
fetch('https://httpbin.org/ip')
.then(r => r.json())
.then(console.log);

2. WebRTC leak test:

// Advanced test for WebRTC leaks
const pc = new RTCPeerConnection();
pc.createDataChannel('');
pc.createOffer()
.then(offer => pc.setLocalDescription(offer))
.then(() => {
const localIP = pc.localDescription.sdp.match(/c=IN IP4 (\S+)/)?.[1];
console.log('WebRTC IP:', localIP); // Should be proxy IP
});

3. Multiple IP verification:

// Check multiple services for consistency
const ipCheckers = [
'https://httpbin.org/ip',
'https://api.ipify.org',
'https://ipinfo.io/json',
'https://icanhazip.com'
];
Promise.all(ipCheckers.map(url => fetch(url)))
.then(responses => Promise.all(responses.map(r => r.json())))
.then(results => {
const uniqueIPs = new Set(results.map(r => r.ip || r.origin));
console.log('Consistent IP?', uniqueIPs.size === 1);
});

If you detect leaks:

  1. Disable WebRTC in browser settings or use extensions
  2. Ensure IPv6 is disabled (IPv6 often bypasses proxy)
  3. Check browser extensions that might make direct connections
  4. Use proxy-aware DNS settings
  5. Consider using GoLogin which handles most leak prevention automatically

Why do some proxies work with certain sites but not others?

Different sites have different detection sophistication and requirements.

Site-specific factors:

const siteFactors = {
detectionLevel: {
basic: 'Only checks IP reputation (many blogs, news sites)',
moderate: 'Basic fingerprint checks (e-commerce, forums)',
advanced: 'ML detection, behavioral analysis (social media, banks)',
extreme: 'Real-time monitoring, device correlation (payment processors)'
},
ipRequirements: {
lenient: 'Accepts datacenter IPs (Wikipedia, GitHub)',
strict: 'Requires residential IPs (Amazon, Instagram)',
extreme: 'Requires ISP proxies or mobile (banking sites, ticketing)'
},
behavioralPatterns: {
tolerant: 'Allows some automation (public APIs, some news sites)',
strict: 'Blocks non-human timing (most social media)',
veryStrict: 'Blocks any suspicious patterns (financial sites)'
}
};

Proxy compatibility by site type:

const compatibilityMatrix = {
'Public APIs': {
datacenterProxy: '✅ Usually works',
residentialProxy: '✅ Always works',
stickySession: 'Not needed'
},
'E-commerce sites': {
datacenterProxy: '⚠️ Often blocked',
residentialProxy: '✅ Usually works',
stickySession: 'Required for checkout'
},
'Social media': {
datacenterProxy: '❌ Almost always blocked',
residentialProxy: '✅ Works, may need rotating',
stickySession: 'Required for account actions'
},
'Financial sites': {
datacenterProxy: '❌ Never works',
residentialProxy: '⚠️ May be blocked',
ispProxy: '✅ Best option',
stickySession: 'Absolutely required'
}
};

Real-world success rates (based on testing):

Site TypeDatacenter SuccessResidential SuccessISP Proxy Success
Wikipedia/Blog95%100%100%
Amazon/eBay25%85%95%
Instagram/Twitter5%70%90%
Banking sites0%40%85%
Government sites80%95%100%

The strategy: Always match your proxy type to your target site’s sophistication. Don’t waste expensive residential proxies on sites that work fine with datacenter IPs.
