PageSpeed Insights scores to SVG

Generate an SVG of your website's PageSpeed Insights scores

Guages

PWA

API and Usage

Important note: Do not embed url, instead embed generated svg

• It takes time to perform audits of website. So embedding it directly would not render due to server timeout. Instead you must first visit and download the svg from the API with the desired parameters. And then embed that svg to your files.
• Typically it takes a few seconds to obtain the results from the pagespeed API
• Some servers don't allow (eg. google.com) or delay (eg. cloudflare) pagespeed crawler, so it may result in unexpected results.
• The results may fluctuate slightly sometimes, you can use the tests parameter to get more accurate perfomance audit results.

API url

The API is called from https://pagespeed-insights-svg.glitch.me

Simple usage

In simple form it will return result for all categories for desktop version of your website. Replace your_website_url with your website's url

https://pagespeed-insights-svg.glitch.me/?url=your_website_url

For example

https://pagespeed-insights-svg.glitch.me/?url=https://correiajpv.com

Theme

Default result is theme-agnostic i.e. looks good in both light and dark environment. But you can force one of two additional themes that are light and dark.

Strategy

Strategy specifies the type of device your website is audited for. You can specify strategy as either mobile or desktop. If none is specified desktop is chosen

https://pagespeed-insights-svg.glitch.me/?url=your_website_url&strategy=mobile

Category

There are 5 categories (in order)

• Performance
• Accessibility
• Best Practices
• SEO
• Progressive Web App

By default all the categories are evaluated, but you can specify which categories to evaluate. The category parameter is a number. This is 5-bit number in binary, where if a bit is 1 then the corresponding category will be included. For example

+------------+------------+------------+------------+------------+
|   Perf.    |    Acc.    |  Best pr.  |     SEO    |     PWA    |
+------------+------------+------------+------------+------------+
|      1     |      0     |      1     |      1     |      1     | => 0x10111 => 23
+------------+------------+------------+------------+------------+
