Network Architecture,
Engineered with
Precision.
The high-fidelity professional environment for modeling, simulating, and validating network topologies with deterministic accuracy.
Drag & drop topology builder with real-time simulation
Full protocol stack — production-grade simulation
“NetPacket replaced our entire Packet Tracer workflow. The browser-based simulation is incredibly accurate and the validation catches issues we'd miss manually.”
“We use NetPacket to prototype every new network topology before deployment. The deterministic engine means what we simulate is exactly what we get in production.”
“The 5 work modes changed how our team collaborates. Design, simulate, validate — all in one tool. Our time-to-deployment dropped by 40%.”
Automated Validation
9 built-in rules catch duplicate IPs, subnet overlaps, missing routes, gateway inconsistencies, VLAN mismatches and ACL conflicts automatically.
