SnakeViz is a browser-based graphical viewer for Python cProfile output, serving as a visual alternative to the pstats module. It runs as a local web application and includes IPython/Jupyter magics for profiling code directly.

Use cases

• visualize python cProfile output in the browser
• find performance bottlenecks in python code
• profile a jupyter notebook cell and see the call graph
• explore a .prof profile file interactively
• replace pstats with a graphical profile viewer
• profile a single line of code with an ipython magic

When to choose

• you need to inspect Python cProfile/pstats data visually
• you want sunburst and icicle call-graph views of where time is spent
• you work in Jupyter/IPython and want inline profiling
• you prefer a lightweight local tool over heavyweight IDE profilers

When to avoid

• you need line-level or memory profiling rather than function-level call graphs
• you are profiling non-Python code
• you need automated continuous performance regression testing
