Cacti vs Sniffnet

Cacti is a free, self-hosted network graphing and operational monitoring framework built around RRDtool. It collects data through SNMP object identifiers or scripts, which can retrieve database information or run other code. Availability checks cover SNMP, ICMP, TCP, and UDP. Discovery and automation can create graphs and data sources, while Remote Data Collectors distribute collection and cache data during network interruptions. Graph items support line, area, stacked, horizontal-rule, vertical-rule, print, and comment types. Device templates connect devices with graph templates and data queries, and plugins can extend collection to other protocols, with WMI listed as an example. Role-based management covers users, groups, and domains. Cacti supports SNMP versions 1, 2, and 3, with a documented limitation for advanced SNMPv3 settings such as SHA224+ or AES192+ when PHP SNMP is used. It is available for Linux/Unix and Windows. Installation requires MySQL, PHP, RRDtool, Net-SNMP, and a PHP-capable web server such as Apache or IIS.

Sniffnet is a free network monitoring app for Linux, macOS, and Windows. It displays overall internet traffic statistics and real-time charts, and can show which programs use bandwidth. Users can choose a network adapter, filter observed traffic, and import or export PCAP capture reports. Sniffnet identifies local network connections, shows remote hosts’ geographical locations, and finds host domain names and ASNs. It recognizes more than 6,000 upper-layer services, protocols, trojans, and worms. Users can configure notifications for network events and import custom IP blacklists to highlight potentially dangerous connections. The app supports live capture, display filters, protocol dissectors, and offline trace analysis; it reads PCAPNG and CAP files as well as PCAP. Custom themes and 26 languages are available. The listed Sniffnet plan is free and the software is open-source under MIT or Apache-2.0. A 2025 security audit reported one low-severity finding, which had been fixed. Most functionality uses offline databases, while reverse DNS lookups provide hostnames for IP addresses.
