Cisco Packet Tracer vs NetSim

Cisco Packet Tracer is a free desktop network simulation and visualization tool for practicing networking, IoT and cybersecurity without physical lab hardware. Simulation Mode lets learners follow data as it travels through a network and analyze traffic. Physical Mode provides practice arranging a device rack and cables. The tool supports adding IoT devices, integrating Python code and practicing network automation. Tutored activities may provide hints, although Cisco says they are available for select courses. Packet Tracer runs on Windows, Linux and macOS, but not on smartphones or tablets. Learners can enroll in Cisco’s free Getting Started with Cisco Packet Tracer course to download the latest version. Installation opens a Packet Tracer Login window and may direct users to a browser for NetAcad sign-in. Some advanced functions, including multi-user Packet Tracer, require network access. On Ubuntu, Cisco’s instructions use the command line with elevated privileges. The Free plan costs nothing and requires course enrollment to download the latest version.

NetSim is a browser-based simulator of Cisco networking hardware and software for certification training. Its preconfigured labs provide the materials needed to complete each objective. Learners can compare their configurations with expected configurations to identify mistakes and get instant feedback, while lab progress and history sync between devices. Labs run in a web browser on modern internet-capable devices without installation; supported systems include Linux, macOS, and Windows. Network Designer lets users create custom labs with complex topologies, devices, connections, annotations, imported icons, and saved device configurations. It is included with the listed certification-specific plans. NetSim also includes the IOS images needed for its labs, without requiring additional licensing of those materials. Listed lab packs cost $29 a year and include 10 or 16 guided labs. Certification plans cost $179 a year and list between 70 and 101 guided labs. Online licenses last one year from purchase and can be used without usage limits during that period.
