# PingXD

> Free website speed test, performance analyzer, and network diagnostic platform. Test website loading times, Core Web Vitals, API response metrics, and network connectivity from global test nodes.

PingXD provides web developers, DevOps engineers, and site owners with real-time performance analytics and network diagnostics. Test from multiple locations worldwide (including India, Singapore, United States, Japan, Germany, and the United Kingdom) across desktop, tablet, and mobile device profiles.

## Diagnostic Tools

- [Website Speed Test](https://pingxd.com/): Measure synthetic website loading speed from global nodes with multi-location comparison and timing breakdowns (DNS, TCP, TLS, TTFB, download).
- [Site Performance & SEO Audit](https://pingxd.com/site_performance): Full Lighthouse and Core Web Vitals audit analyzing performance score, FCP, LCP, CLS, TBT, Speed Index, accessibility, best practices, and SEO.
- [Ping Test](https://pingxd.com/ping_test): Low-latency ICMP/TCP ping test to measure packet response times, jitter, and network reachability from multiple regions.
- [API Speed Test](https://pingxd.com/api_test): Test REST API endpoint latency, response headers, and payload throughput with configurable HTTP methods (GET, POST, PUT, DELETE).
- [Traceroute Test](https://pingxd.com/traceroute_test): Map network hops, detect routing loops, and isolate regional latency bottlenecks between test nodes and destination hosts.
- [DNS Lookup](https://pingxd.com/dns_test): Query authoritative DNS records (A, AAAA, CNAME, MX, TXT, NS, SOA, SRV) to verify domain configuration and propagation.
- [Port Check](https://pingxd.com/port_check): Verify open TCP ports and firewall accessibility on any domain or IP address.
- [Nmap Security Scan](https://pingxd.com/nmap_scan): Scan remote hosts for open ports, running services, and software versions with Quick, Full, or Custom scan modes.
- [MX Record Lookup](https://pingxd.com/mx_test): Verify mail exchange (MX) DNS records and test mail server reachability for email deliverability troubleshooting.
- [IP Geolocation & ASN Lookup](https://pingxd.com/ip_info): Inspect public IP address geographic location, ISP, autonomous system number (ASN), and network hostname.
