I dunno, https://www.rrweb.io/ comes close (closer?) and it's open source.
Replay deterministically replays the recording, so if the state of the application when you recorded it caused a network call, then when replaying it we will also "make" a network call _but_, instead of actually going out to the network we will instead return the exact data that was returned when you recorded it.
You can learn more about how Replay works here https://medium.com/replay-io/how-replay-works-5c9c29580c58
Can you expand more on what you mean by a race condition in network calls? If it's a series of network calls that the browser could make in any order than we will make them in the order that they occurred when you recorded it. If it's a race condition that occurs in your backend, then the Replay browser won't really help there (though it will show you the responses you got from your backend when you recorded it).
For help with that, you might want to use Replay on the backend. Right now we have Node support (https://github.com/RecordReplay/node), but other runtimes are on the roadmap.
Great diagnostics! We'll have to adjust our compilation settings to target a broader browser set.
I've filed an issue regarding the right click issue. That's a fair comment: https://github.com/RecordReplay/devtools/issues/3615
Surely not as fully featured, but the general idea has been possible for ClojureScript Re-frame with: https://github.com/day8/re-frame-10x
For Python, but only if execution is deterministic, I made a small library that tries to address that issue: https://github.com/breuleux/breakword (it prints data alongside a deterministic list of words and you can set a breakpoint on a word of interest in a second run).
It's really a poor man's replay, though. That tool looks really slick, I'll definitely give the Python version a go if/when it comes!
