Website Uptime Monitor - Response Time, SSL, and Security Headers

Check if any website is up, measure response time and TTFB, validate SSL certificates, and audit security headers. Returns performance grades (A-F) and a security score for each URL.

What does Website Uptime Monitor do?

Input a list of URLs and get back a comprehensive health report for each: HTTP status, response time, time to first byte, SSL validity, and security header analysis (HSTS, CSP, X-Frame-Options, X-Content-Type-Options). Each site gets a performance grade and security score.

Key features:

✅ Response time + TTFB measurement
✅ SSL certificate validation
✅ Security headers audit with A-F grading
✅ Content verification (check if a string appears on the page)
✅ Handles timeouts, DNS failures, and connection refused gracefully

How much does it cost?

Pricing: Pay per event — $1 per 100 URLs checked
Typical use: Monitoring 10 websites daily ≈ $3/month

Input example

{
    "urls": ["https://google.com", "https://github.com", "https://example.com"],
    "checkSSL": true,
    "timeout": 30000
}

Output example

{
    "url": "https://google.com",
    "domain": "google.com",
    "status": "up",
    "statusCode": 200,
    "responseTimeMs": 187,
    "ttfbMs": 142,
    "performanceGrade": "A",
    "securityHeaders": { "hasHSTS": true, "hasCSP": false, "score": 2, "grade": "C" },
    "ssl": { "valid": true, "handshakeMs": 95 },
    "isUp": true
}
