Netropy Network Emulator
What Netropy Network Emulator is
Netropy Network Emulator reproduces network conditions so teams can evaluate application performance in a controlled laboratory. It can impose bandwidth limits, latency, jitter, packet loss, corruption, and congestion, with operation described at speeds up to 400 Gbps. Each emulation engine can represent up to 30 WAN links, and parameters can be changed while tests run. Capture and replay records real delay and loss behavior for later analysis. Packet filtering and background utilization are also available. A REST API supports automation, CI/CD integration, and scripting languages such as Python. Apposite offers hardware appliances, NetropyVE for VMware vSphere and KVM, and NetropyCE for cloud testing through AWS Marketplace. Netropy 4.0 adds a browser interface with a topology editor and profiles for Wi‑Fi, 5G, SD‑WAN, cloud, and satellite conditions. Pricing is available on request, with a five-day trial and no free plan.
