Launching Spall-native in beta today!
https://gravitymoth.itch.io/spall

If you're not familiar with Spall, it's a profiler with a zippy frontend.
There's a free/open-source web-version to play with over at https://gravitymoth.com/spall/spall-web.html

The web version has C/C++ support, integration with Odin via core:prof/spall, and chrome://tracing JSON file compatibility.

The native version has all that, and it can handle much bigger files, loads faster, has function latency histograms, runs on Windows, OSX, and Linux, can launch from the command line, and supports a new auto-tracing format which is faster/more compact, for doing LARGE traces, like the one I took of Python a week or two ago.
