EVE-NG vs NetSim by Tetcos

EVE-NG is a clientless network emulation platform for network, security, and DevOps professionals. It is presented for building virtual proof-of-concept projects, solutions, and training environments for organizations, educators, individuals, and groups. A topology designer supports lab creation, configuration import and export, XML lab files, and picture or map imports. Running nodes can connect through hot links, including to real networks. Listed Professional features include KVM hardware acceleration, Docker and custom Docker support, and up to 1024 nodes per lab. Integrations include RADIUS and Microsoft Active Directory authentication, Docker-integrated Wireshark, and an integrated NAT cloud. Hosting options include Proxmox, VMware platforms, and Google Cloud platform VMs. The free plan allows 7 nodes per instance and 63 per lab, with the Admin role only. EVE-NG Base and RBL are priced on request; RBL supports multiple roles, with added roles priced separately. Community Edition support and end of life ended in June 2026.

NetSim by Tetcos is a packet-level, discrete-event simulator and emulator for wired and wireless communication networks. It models end-to-end 5G and 6G systems with gNB, UE, 5G Core, MIMO, beamforming, network slicing, and configurable propagation. Each 5G stack layer includes C source code that users can modify for custom protocols, while an external Python interface supports automation, AI/ML workflows, and runtime control. Standard and Pro editions interface with Python, MATLAB, SUMO, and Wireshark. The Emulator connects simulations with real hardware and live applications, applying configured delay, loss, and error conditions. NetSim Cyber adds network and attack emulation for power-system cyber-physical testbeds and interfaces with listed power-system tools. Licensing can remain local through on-premises floating deployment, and cloud licensing exchanges only handshake data. NetSim runs on Windows; emulator setup specifies a dedicated Windows 10 or 11 machine.
