-| [psutil](https://psutil.readthedocs.io/en/latest/)            | System monitoring, profiling, limiting process resources and the management of running processes.                                                                                                                                           | 🟢  |
-| [pyinstrument](https://pyinstrument.readthedocs.io/en/stable) | Python profiler. Tells you how long individual lines of code take to run, so you can focus on the slowest part of your program to speed it up.                                                                                              | 🟢  |
-| [snakeviz](https://jiffyclub.github.io/snakeviz/)             | Browser based graphical viewer for the output of Python’s cProfile module.                                                                                                                                                                  | 🟢  |
-| [line_profiler](https://pypi.org/project/line-profiler/)      | A tool for line-by-line profiling of functions.                                                                                                                                                                                             | 🟠  |
-| [memray](https://bloomberg.github.io/memray/)                 | Tracks and reports memory allocations, both in Python code and in compiled extension modules. It also has a [plugin](https://pytest-memray.readthedocs.io/en/latest/) for easy integration with pytest. Only works on Linux and macOS.      | 🟠  |
-| [memory_profiler](https://pypi.org/project/memory-profiler/)  | No longer actively maintained. A Python module for monitoring memory consumption of a process alongside line-by-line analysis of memory consumption. Might be a useful alternative to memray if you need to do memory profiling on Windows. | 🟠  |
