Compare

Understand regressions by comparing your HAR files.

Drop HAR files here (max two) or click to upload. You can add .har and .har.gz files.

Or add the URL to your HAR files and press compare:

Or use a Github gist.

Need help?

You can add a URL to a HAR file or the URL to a specific sitespeed.io run and we will automagically find the HAR. You can also compare two HAR files on the fly that are available on the internet. You can use a Github gist or add the parameters ?har1=FULL_URL1&har2=FULL_URL2&compare=1 and the two HAR files will be compared. If you need more help, look at the introduction video or please create an issue at Github.
