Debugging microservices applications is a difficult task. The state of an application is spread across multiple processes, often on different nodes. It is hard to get the holistic view of an application's state. Certain tools exist for troubleshooting microservice issues. OpenTracing can be used to produce transaction or workflow logs for post-mortem analysis. Service meshes like Istio can be used to monitor the network to identify latency problems. Unfortunately, these tools are passive, the feedback loop is slow, and they do not allow you to monitor and alter the application during run time.

Squash brings the power of modern debuggers to developers of microservice apps. Squash bridges between the apps running in a Kubernetes environment (without modifying them) and the IDE. Users are free to choose which containers, pods, services or images they are interested in debugging, and are allowed to set breakpoints in their codes, follow values of their variables on the fly, step through the code while jumping between microservices, and change these values during run time.
