About Local Storage Manager

Local Storage Manager is a developer tool for inspecting and managing browser localStorage in a dedicated, full-page workspace. It allows developers to safely view, edit, and delete localStorage keys for the active website. The extension focuses on clarity, predictability, and control. All actions are user-initiated, and no data ever leaves the browser. Features include viewing all localStorage keys and values for the current site, editing and deleting individual keys, bulk actions for managing multiple keys, JSON detection with optional formatting and minification, and storage size visibility to help diagnose quota issues. Each site opens in its own dedicated workspace tab. Designed for developers, the interface is minimal and distraction-free, with predictable behavior and no silent data modification. The extension works entirely locally with no external services.
