DIAGNOSE
Run network diagnostics with latency, packet loss, jitter, and hop analysis. Distance-aware verdicts know distant links should read healthy, not degraded.

SECURITY
Inspect SSL certificates with full chain validation, then scan ports with three-state results that distinguish closed from filtered. Detect services by banner and review security headers.

LOOKUPS
Resolve DNS records and check propagation globally across multiple resolvers. Query WHOIS, reverse DNS, MAC vendors, and IP reputation.

BGP
Run advanced routing analysis with live data. Plus full offline analysis for path selection, policy testing, attribute decoding, and configuration help.

TRACE
Follow packets hop by hop. Identify latency, drops, and anomalies along the path.

MONITOR
Continuous ICMP and HTTP monitoring with scrollable historical graphs. SLA tracking, anomaly detection, per-target thresholds, maintenance windows, SSL expiry alerts. Background-safe across reboots.

PLAYBOOKS
Run automated diagnostics for common scenarios. Each runs the right sequence for the job.

BRIEFING
Get instant health summaries combining the essential checks for any target.

GEOLOCATION
Identify source and destination locations with distance, country, ASN, hosting type, and CDN edge proximity for any IP or hostname.

CALCULATORS
Plan and verify networks: subnet calculation, supernet, overlap detection, route summarization, and VLSM allocation.

CONVERSIONS
Convert numbers and byte units, parse URLs, analyze TTL for OS fingerprinting, and format MAC addresses.

BANDWIDTH & LATENCY
Calculate throughput, transfer time, propagation delay across distance and medium, and round-trip time.

HISTORY
Save, search, re-run, and share past sessions. Same-day repeats collapse into one row while date boundaries stay visible for trends. Cancelled sessions stay distinct from healthy and failed ones.

IN-APP HELP
Complete in-app reference covering commands, gestures, screens, terminology, and FAQ. 77 topics, 41 commands across 7 sections, with aliases and examples.

BACKUP
Export full configuration, monitors, recents, and history as an AES-256 encrypted file. Restore on any device with password.

PRIVACY
No accounts, analytics, or tracking. Data stays on-device. Network calls only go to targets you test or BGP data sources.

FOCUS
Minimal permissions, no bloat, no background noise. Fast, stable, stays out of your way.

Built for network engineers who follow the packets, not assumptions.
