WHAT'S UNDER THE HOOD
See Your Connection Clearly
Real-time analysis with the metrics that actually matter - latency, packet loss, and throughput at a glance. Know your connection before your users do.
Discover Everything on Your Network
Automatic UPnP and Bonjour service discovery maps every device and service broadcasting on your network. No guesswork, no blind spots.
Ping & Traceroute
Track reachability and trace the exact path your data travels - hop by hop. Pinpoint latency spikes and routing failures the moment they appear.
Port Scanner
Expose open ports before attackers do. A fast, precise scan of your network's attack surface, with results you can act on immediately.
DNS Lookup
Instant DNS record retrieval across all record types. Resolve misconfigurations, verify propagation, and troubleshoot resolution failures without leaving the app.
SIP Proxy Verification
Confirm your VoIP infrastructure is reachable and responding. Keep communication systems healthy with on-demand SIP proxy status checks.
SMB Inspector
Check SMB availability and basic endpoint details to validate file-sharing services and troubleshoot access issues quickly.
SSH Inspector
Confirm SSH reachability and banner details so you can verify remote access paths before opening a terminal.
LDAP Inspector
Verify LDAP endpoints are reachable and responding so directory-backed services stay discoverable and dependable.
RDP Inspector
Confirm Remote Desktop endpoints respond as expected and spot access issues before users report them.
TLS Certificate Inspector
Full certificate chain inspection - SANs, key algorithms, expiry, and security headers. Know exactly what your TLS configuration is saying to the world.
Security Analysis
SPF, DMARC, CAA, and HSTS checks in one place. Verify your domain's security posture without juggling a dozen separate tools.
WHOIS & Domain Intel
Registrar, nameservers, registration, and expiry dates - all pulled directly over TCP port 43. Fast, accurate, no third-party web lookups.
Wake on LAN
Wake any device on your network with a broadcast magic packet. Manage known MAC addresses and power up machines without leaving the app.
Subnet Calculator
Clear, visual subnet math. Calculate host ranges, broadcast addresses, and CIDR breakdowns without reaching for a separate calculator.
HTTP Header Inspector
Full response headers for any URL. Debug redirects, verify caching policies, and inspect security headers in real time.
UPnP Media Browser
Browse ContentDirectory services, navigate containers, see album art, artist names, and duration. Stream audio directly. Paginate libraries over 200 items.
Built for people who need answers, not guesses.
