OPFS Explorer

OPFS Explorer - The Missing DevTools Panel for Origin Private File System

The Origin Private File System (OPFS) is a powerful browser API for high-performance file storage, but browsers don't provide any way to see what's inside. OPFS Explorer fills this gap by adding a dedicated panel to Chrome DevTools.
