CLI 🖥 + API for Google PageSpeed Insights

PythonPSI PyPI - Downloads

PyPSI

PageSpeed Insights (PSI) reports on the performance of a page on both mobile and desktop devices, and provides suggestions on how that page may be improved.

PSI provides both lab and field data about a page. Lab data is useful for debugging performance issues, as it is collected in a controlled environment. However, it may not capture real-world bottlenecks. Field data is useful for capturing true, real-world user experience - but has a more limited set of metrics.

PyPSI uses PageSpeed Insights API v5

Installation

pip install PythonPSI
