Create a HAR file for troubleshooting performance issues

During troubleshooting, our Customer Support team may ask you to send us a HAR file from your browser to diagnose performance issues or bugs in Basecamp. A HAR file provides valuable information that helps our team investigate and fix problems.

Here's how to create that file, depending on your browser:

  1. Open Developer Tools from the View menu > Developer > Developer Tools (or press Cmd + Option + I on Mac, Ctrl + Shift + I on Windows).
  2. Click the Network tab in the Developer Tools pane.
  3. Check Preserve Log.
  4. Refresh the page and reproduce the issue.
  5. Click the download icon ↓ at the top left of the Developer Tools pane to save the log and send it to our team.
  1. Enable the Develop menu by going to Safari menu > Settings > Advanced and checking Show features for web developers.
  2. Open the Web Inspector by going to the Develop menu and selecting Show Web Inspector (or press Cmd + Option + I).
  3. Click the Network tab.
  4. Click the Settings gear icon (⚙) in the Network tab and uncheck Clear when page navigates so your logs persist across page loads.
  5. Click the Clear Network items button in the top-right of the Network tab (or press Cmd + K) to clear any existing entries.
  6. Refresh the page and reproduce the issue.
  7. Click the export icon (an upward arrow/share icon) in the top-left corner of the Network tab's content pane to save the .har file to your computer.
  1. From the Tools menu, go to Browser Tools > Web Developer Tools.
  2. Select the Network tab from the Web Developer Tools pane.
  3. Click the gear icon (⚙) at the top right and select Persist Logs.

  5. Click the gear icon (⚙) at the top right again and select Save All as HAR.
  1. Press F12 to open DevTools, or go to More tools > Developer tools from the toolbar menu. If the Network tab isn't visible, click the More tools (+) button and select Network.
  2. From the Network tab, select Preserve log.
  3. Reproduce the issue.
