Sitespeed.io report showing only few metrics after testing on safari

[imakhnyboroda]

Hi! I am doing a safari test and I am wondering if it is expected that I do not have as many metrics as in Chrome

I used for running test this command:
sitespeed.io --name "Desktop TU safari" -b safari -n 20 https://[my url]/

Hi @imakhnyboroda yes it is. We lack many metrics from Safari:

• Safari lack implementation of a lot of performance metrics direct in the browser
• We also miss out on getting a HAR file from Safari (I have an open feedback assistant number for that)
• On desktop you can get visual metrics if you follow the instructions on https://www.sitespeed.io/documentation/sitespeed.io/installation/#mac to get the extra things you need.
• For Safari on iOS there's an open issue for a fixing the video and visual metrics see Video/Visual Metrics on Safari iOS do not work browsertime#1598
