Data Traffic Generator Tool

Traffic Generation from Captured Production Traffic

Capture, Reproduce, and Amplify Production Traffic in a Controlled Lab Environment

When it comes to traffic generator tools, you want something simple to use that delivers insightful, actionable results. With AppPlayback, you can easily reproduce and amplify your real-world network traffic in a test environment to identify potential pitfalls on your network. AppPlayback effectively emulates clients and servers to quickly validate the performance of network devices.

As a data traffic generator, AppPlayback can amplify a single flow into millions of flows to perform a network load test. It isolates any application flow to replay at scale. Thanks to its ease of use and extensive features, AppPlayback stands out among traffic generator tools.

Validate Performance with Real Production Traffic

Capture production network conditions and convert them to dynamic traffic configurations for fast, easy fault analysis. Emulate clients, servers, and amplify recorded traffic for reliable validation of architectures and devices prior to deployment.

AppPlayback Traffic Generation


  • Record and replay traffic with the same application mixes, protocols, and user behavior as your real production network.

  • Stress test network devices at tremendous scale by amplifying a single flow into millions of flows.

  • Ensure quality of service of products and quality of experience for customers.
  • Validate the performance of network devices like WAN accelerators and SD-WAN gateways.

  • Find and eliminate performance bottlenecks on your network before they reach your end user.

  • Replicate crashes and bugs to troubleshoot application failures and build fixes faster.

Configure Dynamic Tests with Ease

Connect from anywhere on our modern, browser-based user interface then configure tests in just a few short steps using our wizard driven process or automate testing with RESTful API.

Integrate with Netropy network emulators for a truly end-to-end performance testing solution.
