  1. py-spy

    Sampling profiler for Python programs

    https://github.com/benfred/py-spy is also really nice, and has an actual oss license.

  3. The license is a bit perplexing at https://gitlab.com/mbryant/functiontrace/-/blob/master/LICEN...

    It says it is licensed under Apache License 2.0, but also under "Prosperity Public License 3.0.0" which limits use for a commercial purpose to 30 days.

  4. pyinstrument

    🚴 Call stack profiler for Python. Shows you why your code is slow!

    Is there something about the actual profiler that differs from existing tools like pyinstrument [1] or py-spy [2]? I know pyinstrument has various output options and I wonder if it could potentially output something readable by the Firefox Profiler tool.
