Stress your lora network-server

status coverage report Go Report Card

When building a big iot lora platform handling millions of messages per seconds, how to be sure we handle all the messages in time ? Today, no publicly accessible tool enables us to simulate the behavior of a wide lora infrastructure along with the messages.

Lorhammer is here to do that. You can launch as much lorhammers as you want to stress and test your network-server.

Lorhammer has been inspired by Gatling but for lorawan networks and with distribution in mind. One day, lorhammer will become hammer with flavours like lorhammer and resthammer…

We want to thank brocaar for his great job on opensourcing his projects, we have been inspired by brocaar/loraserver and particularly brocaar/lorawan which we use in lorhammer.

Lorhammer is a project powered by itk. We use it internally to choose the right network-server for our IoT infrastructure. Furthermore, we use it to run integration tests every time we accept merge-request (same thing as a pull-request but in the gitlab world). Indeed, for every new update, a stress test is launched over our IoT plateform and checkers check if all is ok, taking in consideration response time delays and data processing.
