Storion Studio

Visual database manager for localStorage, sessionStorage & IndexedDB. SQL-like queries, CRUD, export/import.

Storion Studio is a visual database manager for your browser—think pgAdmin for localStorage, sessionStorage, and IndexedDB. Inspect, edit, and manage client-side data with a clean, professional interface—no backend required. WHAT YOU CAN DO • Manage multiple databases: Create, rename, and delete databases and keep your data organized by project or app. • Design tables with custom columns: Define table schemas (id is always included), add columns, and adjust structure as your app evolves. • Full CRUD in a table grid: Insert, view, edit, and delete rows in a spreadsheet-like grid with pagination and clear actions. • Run SQL-like queries: Use the built-in query engine to filter and transform data without writing code. • Export and import: Backup entire databases as JSON or restore from a backup with one click. Perfect for migrating data or sharing fixtures. • Monitor storage usage: See real-time usage against the 5MB localStorage limit so you never hit quota surprises. • Sync with your web app (optional): Built on the Storion engine—if your site uses the Storion library, you can stream change events between the extension and your app for a seamless admin experience. BEST FOR • Front-end and full-stack developers debugging or prototyping apps that use localStorage or IndexedDB • Anyone who wants to inspect or edit site data stored in the browser without opening DevTools manually • Teams that need a simple way to backup, restore, or migrate client-side databases Storion Studio is fast, lightweight, and runs entirely in the browser. No external servers, no sign-in required—just install and start managing your data.
