Network Snapshot

Network Snapshot records and compares services that nearby devices choose to advertise on your local network. Start discovery only when you need it. The app looks for eight declared web, print, media, file-sharing, and remote-access service types. You can also check one host and one port that you enter. The app never scans a port range. Save snapshots on your device and reopen them after relaunch. Compare added, removed, and changed services or host results. Export readable JSON. No account is required. The app has no advertising, analytics, or tracking. It uses no remote server or cloud service and never sends or uploads snapshots. Snapshots stay on your device unless you choose to export them. Network Snapshot is not a complete device inventory. It does not collect MAC addresses. It does not scan for malware. It does not certify network security. The app interface is available in English, German, Spanish, French, Italian, Japanese, Korean, Brazilian Portuguese, Simplified Chinese, Traditional Chinese.
