OPFS Explorer – DevTools panel for inspecting Origin Private File System

Summary: OPFS Explorer provides a developer tool to inspect and manage files stored in the Origin Private File System, which browsers do not natively expose. It supports full file operations beyond read-only access, aiding debugging of SQLite Wasm, File System Access API, and offline PWA storage.

What it does

It offers a DevTools panel to view and perform CRUD operations on files stored via in OPFS, overcoming the default invisibility of this storage.

Who it's for

Web developers working with OPFS, SQLite Wasm, File System Access API, or offline Progressive Web Apps needing direct file inspection and manipulation.

Why it matters

It solves the lack of native browser tools for inspecting and managing OPFS files, simplifying debugging and development workflows.
