What does HackerNews think of panopticon?

I'll throw in my own too: https://github.com/kunalb/panopticon

I built https://github.com/kunalb/panopticon to export perfetto/chrome compatible traces and also draw arrows between async functions. (I think the arrows are only supported in about://tracing though).

I've built https://github.com/kunalb/panopticon to easily trace function execution to handle a similar use case, except that it generates output for chrome://tracing instead of printing out lines.

cPython's settrace/setprofile functionality enables so many cool tools.

I wrote and open sourced something very similar recently: https://github.com/kunalb/panopticon. I don't think it's as sophisticated as function trace, but it generates chrome/catapult compatible traces instead and has some additions for async coroutines/generators.

Firefox's profiler looks pretty cool, I wish it could also accept catapult traces as is -- it doesn't seem to be the case. Now I know of:

- chrome://tracing - Firefox's profiler - Perfetto: https://ui.perfetto.dev/#!/ - Speedscope: https://www.speedscope.app/ - Brendan Gregg's flamegraph generator

to help visualize traces. Are there other good ones?
