vprof is a Python package providing rich and interactive visualizations for Python program characteristics such as running time and memory usage. It runs as a CLI tool and renders CPU flame graphs, profiler stats, memory graphs, and code heatmaps in the browser using D3.

Use cases

• profile cpu usage of a python script with a flame graph
• visualize memory usage of python code line by line
• generate a code heatmap showing execution counts and run times
• profile a single python function remotely and view results in the browser
• save profiling results to a file and render them later

When to choose

• you want interactive, visual profiling output instead of text-based profiler reports
• you need to inspect both CPU and memory characteristics of Python programs
• you want to profile individual functions via a remote server mode

When to avoid

• you need CPU flame graphs on Windows, which are not supported
• you need a profiler under very active development with frequent updates
• you need profiling for non-Python languages
