nChronos vs PCAPdroid

nChronos is Colasoft’s application-focused network performance analysis system for medium and large corporate networks. Its client/server design places continuous packet capture, analysis, storage and data mining on a server, while a console displays and analyzes the collected data. The server can receive traffic through a network mirror port or link tap and retain packets for later investigation of network or application problems. Real-time statistics and user-defined alerts show network events as they occur. System or custom reports can be scheduled for hourly, daily, weekly or monthly email delivery. Users can define application and transaction monitoring, with profiles for HTTP, FTP, email and DNS. Packet files can be replayed from Colasoft, libpcap and several vendor formats, including files associated with Wireshark, Ethereal and Tcpdump. Linux server systems and Windows consoles are listed, with browser-based server configuration. Standard specifications allow four logical links, eight capture interfaces and two concurrent server connections.

PCAPdroid is an open-source Android network capture and monitoring tool that works without root privileges. It uses Android VpnService to receive app traffic, then processes it locally without creating an external VPN. Its connection view shows protocol, ports, addresses, status and traffic volume. Captures can be saved as PCAP files or sent remotely for analysis, and the app supports offline trace analysis, display filters and command-line capture. It can decrypt HTTPS/TLS traffic for a specific app, subject to Android certificate trust limitations. The free plan covers core monitoring and capture; paid features add a firewall for blocking apps, domains and IP addresses with configurable rules and allowlists, as well as malware detection using third-party blacklists and PCAPng format. PCAPdroid supports real-time PCAP-over-IP analysis with tools such as Wireshark, ntopng and tcpdump. In non-root mode it captures only outgoing connections started by the device running it, not traffic from other devices on the network. The project says it collects no information and processes traffic locally.
