OPFS Explorer is a Chrome DevTools extension developed by Thomas Steiner. It falls under the category of Browsers and specifically belongs to the Add-ons & Tools subcategory. This free extension allows users to explore the Origin Private File System (OPFS) of a web application.

To use OPFS Explorer, simply open Chrome DevTools and click on the OPFS Explorer tab. The extension will automatically analyze the OPFS of the current web application and present a file hierarchy. Users can then click on any file to download its contents or delete the file, although deletion may fail if the file is locked. It is important to note that deleting files may potentially disrupt the functioning of the web application.
