Summary

OPFS Explorer is a Chrome DevTools extension that allows you to explore the Origin Private File System (OPFS, https://fs.spec.whatwg.org/) of a web application.

To use it, 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 (https://tomayac.github.io/opfs-explorer/).

sometimes it's not work and opfs menu don't showed in dev tools

1. Very basic explorer that works with the tomayac test page. Seems to only support very simple listing, deleting and "downloading" of files. But not creating new files or copying files into OPFS. 2. Hangs forever on "⌛Analyzing Origin Private File System" if the page you're opening it on doesn't make use of OPFS. It would be better to show an empty filesystem instead of hanging forever. 3. Also it doesn't seem to show the OPFS files of a browser extension that is storing data in OPFS. It just hangs on "⌛Analyzing Origin Private File System" again. Apparently it's not useful for debugging browser extensions.

Simple, straightforward, and it has specific support for showing certain metadata about sqlite3 "OPFS SAH-Pool" databases (that's actually really useful for me).
