This is very cool, solving some issues I no doubt many people have when writing tests against a (fast-)moving target. I'll definitely give it a try in my next project.

I looked through the codebase, and noticed that this uses a custom data format to persist HTTP requests and responses in local storage. I'm not sure if it's technically possible in all circumstances, but I think it might be valuable to have requests and responses be stored as HAR 1.2 [1] when possible, so that the trace can be used by other tools [2] to aid in debugging, verifying and analyzing behaviour as well as perhaps automated creation of load/performance tests.
