Website Monitoring Tools

Run uptime checks, response-time tests, SSL health probes, and multi-region reachability checks against any host — on demand, directly from our network. Use them to diagnose an ongoing incident, validate a deployment, or establish a baseline before launch. For continuous monitoring with alerting, see Website Monitoring →

Monitors

HTTP Request

Send HTTP requests with custom method, headers, body, and authentication — inspect the full response.
HTTP Request Timing

Load a URL in headless Chromium and stream every fetched resource with size and timing.
CORS Tester

Test any URL for CORS (Cross-Origin Resource Sharing) with a custom method, headers, and body — see exactly why a browser would allow or block the request.
Dead Link Checker

Crawl a website and find broken internal links — renders JS pages with a headless browser.
Site Exposure Scanner

Probe a website for exposed config files, backup dumps, admin panels, and missing security headers — the same ~120 checks attackers run.
Site Standards Check

Verify a site publishes security.txt, robots.txt, sitemap.xml, app-linking files, and other well-known disclosure standards.
Ping Host

Send ICMP echo requests and report RTT and packet loss.

Monitor this automatically

NetTests can run these checks on a schedule, preserve historical results, compare changes over time, and alert you the moment something breaks.
