HAR Mapper

Select a HAR file (or drag and drop)

Need help getting a har file? Most performance tools should give you the option to download a har (HTTP Archive) file, you can also get them from browser developer tools:

• Google Chrome
• Mozilla Firefox

Note that some tools (including Firefox) do not include initiator data in har files, so all resources will be attributed to the first request.

This is a prototype built by @SimonHearne, get in touch with any bugs or feature requests.
