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

Usage

Google seems to have made it mandatory to use an API key, otherwise you may reach service quota limits too soon. Get one from here.

psi <SITE_URL> <OPTION1> <OPTION2> ...

Example:

$ psi developers.google.com --category seo --stratergy desktop --locale en

    {
    "captchaResult": "CAPTCHA_NOT_NEEDED",
    "kind": "pagespeedonline#result",
    "id": "https://developers.google.com/",
    "loadingExperience": {
