I love it, I always wished for something like that. Will try to later test with python. Wish there was also for JS/TS. As for rr debugger did it got by now any support for MacOS or Windows or Android? I'm also wondering how heavy are those recording for typical apps.

This would be also great for LLM to give some context via MCP server or even let LLM pick what variables history wanna see instead of giving full recording file.

Also nice would be some recording filtering that you wanna e.g. pick few variables and display history during whole execution maybe with some specific formating and maybe even for some numeric variables or like tensors, images, etc pass to rerun for visual debugging so you can see plot it
