Ostinato: The Network Traffic Generator for Testers, Developers, and Engineers Ostinato is a powerful and intuitive network traffic generator designed to help network engineers, developers, testers, and educators build, test, and validate networks, devices, and applications with precision. Whether you’re developing a new router firmware, testing firewall throughput, validating DPI rules, or simulating protocol behavior, Ostinato gives you complete control over the packets you generate — no scripting required (unless you want it!). With Ostinato’s visual GUI and API controlled agents (Drones), you can craft packets from scratch or tweak them field-by-field to simulate any traffic scenario. Need to simulate bursts, generate traffic at line-rate, or perform performance testing across multiple interfaces? Ostinato handles it all — with support for Ethernet, VLAN, IPv4/IPv6, TCP, UDP, ICMP, ARP, and many more protocols. For automation and integration into CI pipelines or test frameworks, Ostinato provides a rich Python API — ideal for scaling test setups or implementing reproducible test cases. And with add-ons like PerfBench for automated RFC 2544 testing and Turbo Transmit for high-speed line-rate generation, Ostinato continues to evolve with enterprise-grade capabilities while staying lightweight and accessible. Key features include: \* Cross-platform GUI for traffic generation — intuitive yet powerful \* Remote agents (Drones) for distributed test setups and headless environments \* Protocol-rich stack with support for a wide range of encapsulations \* Python API for automation and scripting \* Multi-platform support including Windows, Linux, macOS, Raspberry Pi, and virtual lab platforms (GNS3, EVE-NG, CML, Containerlab) \* Flexible licensing with tiers for individual users, teams, and enterprises Ostinato is trusted by networking professionals, test engineers, and educators in 75+ countries for lab testing, performance benchmarking, vendor evaluations, and classroom instruction. It bridges the gap between free open-source tools and expensive proprietary appliances — offering professional-grade features at accessible pricing. Whether you're testing at 10 Mbps or 100 Gbps, in the cloud or on-prem, Ostinato gives you the control and flexibility to generate the traffic you need — when and where you need it. Build. Test. Validate. — with Ostinato.
