Debugging microservices applications is a difficult task. The state of the application is spread across multi microservices and it is hard to get the holistic view of the state of the application. Currently debugging of microservices is assisted by openTracing, which helps in tracing of a transaction or workflow for post-mortem analysis, and linkerd and itsio which monitor the network to identify latency problems. These tools however, do not allow to monitor and interfere with the application during run time.
In contrast, "traditional" debuggers of monolitic application provide devs with powerful features like setting breakpoints in their codes, following values of variables on the fly, stepping through the code, and changing these variables during run time.
Squash brings the power of modern popular debuggers to developers of microservices apps that run on container orchestration platforms. Squash bridges between the orchestration platform (without changing it) and 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.
Squash is built to be easily extensible, allowing – and encouraging – adding support for more platforms, debuggers and IDEs.
To learn more about the motivation behind project squash, read our blog post or watch a recorded demo. We also encourage you to read squash technical overview blog.

Squash is still experimental! APIs and compatibility are subject to change. We are looking for community support to help identify potential bugs and compatibility issues. Please open a Github issue for any problems you may experience, and join us on our slack channel
Squash would not be possible without the valuable open-source work of projects in the community. We would like to extend a special thank-you to Kubernetes, gdb and dlv.
