Inferred product pattern

Utility-focused DevTools extension offering a bridge to missing browser capability.

Review-backed pain points

Users report the tool hangs indefinitely on pages without OPFS usage, crashes the browser on macOS, and fails to load the DevTools menu intermittently.

Observed feature gaps

Lacks support for file creation, file copying into the OPFS, and struggles to inspect storage used by other browser extensions.
