Is there a visual profiler for Python?

python user-interface profiling profiler

I use cProfile now but I find it tedious to write pstats code just to query the statistics data.

I'm looking for a visual tool that shows me what my Python code is doing in terms of CPU time and memory allocation.

Some examples from the Java world are visualvm and JProfiler.

  • Does something like this exist?
  • Is there an IDE that does this?
  • Would dtrace help?

I know about KCachegrind for Linux, but I would prefer something that I can run on Windows/Mac without installing KDE.

A friend and I have written a Python profile viewer called SnakeViz that runs in a web browser. If you are already successfully using RunSnakeRun SnakeViz may not add that much value, but SnakeViz is much easier to install.

Edit: SnakeViz supports Python 2 and 3 and works on all major systems.
