Our verdict on NetSim
NetSim is a browser-based network simulator from NetSim Labs for students, hobbyists, networking professionals, and training organizations. Its Rust/WebAssembly engine supports multi-vendor CLI practice for Cisco, Huawei, Aruba, and MikroTik configurations, alongside networking labs and an AI Copilot. The web-based format covers practice in the browser, while the free tier supports topologies of up to 15 devices.
The pricing structure starts with a capable Free plan available at no cost. It includes the full simulator engine, all vendor CLIs, 10 basic labs, AI Copilot with BYOK, and local storage. Pro costs $15 per month and adds 35+ advanced labs, unlimited devices, included AI Copilot access, cloud synchronization across devices, and priority support. Enterprise adds SSO/SAML integration, an instructor dashboard, LMS integration through LTI, custom lab creation, and dedicated support. The main upgrade path is therefore from individual practice to broader lab access and synchronization, then to instructional administration.
NetSim fits organizations that need browser-based configuration practice with a defined training workflow. Enterprise’s instructor dashboard, custom labs, and LTI integration make it more suitable for training organizations than the Free or Pro tiers. Its multi-vendor focus also suits learners working across Cisco, Huawei, Aruba, and MikroTik environments. Choose it for guided networking practice, AI-assisted help, and cloud synchronization on Pro. An alternative may be more appropriate for teams requiring discrete-event simulation, real-time emulation, hardware-in-the-loop support, or an automation API.
