Every tool you need

Nine powerful diagnostic tools, all in one lightweight app designed for clarity and speed.

Ping Test
Measure latency and packet loss to any host using TCP Connect. Configurable count and timeout.
Port Scan
Fast TCP port scanning with support for single ports, lists, and ranges. Async execution keeps the UI responsive.
Subnet Scan
Discover all devices on your local network via ARP. All data stays on your device — never uploaded.
DNS Lookup
Resolve any domain with custom DNS servers. Supports A, AAAA, MX, CNAME, TXT, and NS records.
Traceroute
Trace the network path to any host, hop by hop. Configurable max hops and timeout.
Speed Test
Test your network bandwidth against global nodes. Measure download, upload, and jitter.
IP Geolocation
Look up the geographic location, ISP, and other details of any IPv4 or IPv6 address.
HTTP Test
Check URL connectivity, response time, status code, and SSL certificate information.
Whois Lookup
Query domain registration data, including registrar, registrant, and expiration date.
