 ## Opening the trace
 
 You can open the saved trace using the Playwright CLI or in your browser on [`trace.playwright.dev`](https://trace.playwright.dev). Make sure to add the full path to where your trace's zip file is located. Once opened you can click on each action or use the timeline to see the state of the page before and after each action. You can also inspect the log, source and network during each step of the test. The trace viewer creates a DOM snapshot so you can fully interact with it, open devtools etc.
