OPFS Explorer is a Chrome DevTools extension that allows you to explore the Origin Private File System (OPFS) of a web application.
Install the extension from the Chrome Web Store (end users) or clone the repo and load the unpacked extension locally (developers).
Open Chrome DevTools and click on the OPFS Explorer tab. The extension will automatically analyze the OPFS of the current web application and display the file hierarchy. You can then click on any file to download its contents or delete the file (which may fail if the file is locked). Note that deleting files may cause the application to break.
You can test the extension on the demo page.
The OPFS Explorer tab has disappeared from DevTools, what do I do?
This happens occasionally and can be fixed by clicking Restore defaults and reload in DevTools settings:
