Emulate a city's worth of IoT devices!


The Valid8 Internet of Things (IoT) Load Tester provides an all-in-one, cost-effective solution for emulating and testing against large numbers of IoT devices.

What It Can Do For You

The Valid8 IoT Load Tester is a fully automatable solution that addresses the unique challenges brought by IoT testing by supporting a wide range of protocols, industries, and manufacturers.

Why It’s Different

  • Scalable software-based architecture can run on a range of hardware from COTS and high-end customer provided hardware to Virtual Machines and the Cloud (e.g. Amazon AWS) for maximum versatility and performance
  • Web-based UI is easy to learn
  • HTTP API enable integration with automation test systems and other equipment
  • Stateful modeling provides accurate emulation of network elements


  • Measure Key Performance Indicators (KPIs) such as number of simultaneous sessions 
  • HTTP, MQTT, COAP, SIP sessions 
  • Generate valid and invalid/negative messages and call-scenarios 
  • Supports sending invalid responses including malformed, dropped and misordered packets
  •  Alerts and notifications

  • Primary DNS Address
  • Secondary DNS Adress
  • MAC Address Public Gateway
  • GTP Tunnel IP Address and Port
  • GTP Tunnel eNodeB IP Address
  • Integrity Algorithm
  • IP Address to assign UEs on LAN

Automation API

User commands can be fully automated using REST API. This includes performing all test control functions as well as collecting results and metrics. It can be integrated into virtually any CI system via the HTTP API, including Jenkins, CircleCI, Gitlab and others. Includes Autom8 Python framework.


The application’s subsystems can be edited directly in the browser using TDL. The Message Workshop allows for the creation of test scenarios directly from the hex stream of a remote capture, while the Composer graphical editor (being deployed for all products in 2021) will allow for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.
