pyheat

Profilers are extremely helpful tools. They help us dig deep into code, find and understand performance bottlenecks. But sometimes we just want to lay back, relax and still get a gist of the hot zones in our code.

A picture is worth a thousand words.

So, instead of presenting the data in tabular form, if presented as a heatmap visualization, it makes comprehending the time distribution in the given program much easier and quicker. That is exactly what is being done here !

Demo

Scroll Demo

Features

• Simple CLI interface.
• No complicated setup.
• Heatmap visualization to view hot zones in code.
• Ability to export the heatmap as an image file.
• Ability to scroll, to help view heatmap of large py files.
