IndexedDB Viewer & Editor — IdxBeaver

IdxBeaver is a database-style client for browser storage, built into Chrome DevTools. Open DevTools on any page and you get a proper data grid, a query editor, row inspector, schema inference, and import/export for IndexedDB, LocalStorage, SessionStorage, Cookies, and Cache Storage — without leaving the browser. Chrome's built-in Application panel treats browser storage as an afterthought: no filtering, no schema awareness, no bulk edits, no query history, no exports that survive a page refresh. IdxBeaver turns it into the workflow you already use with a real database client. Features • IndexedDB browser — discover every database and object store across every frame of the origin. Inspect records in a zebra-striped grid with column pinning, resizing, sticky headers, and inline editing. • Query editor with MongoDB-style filters — filter, project, sort, and limit your data with a JSON query language. Index-aware plan selection, with an in-memory fallback for compound operators. The chosen plan is shown alongside results. • Multi-tab query workspace — keep several queries open at once, each with its own editor and results pane. Save queries you reuse and reopen them in a click. • Row inspector — per-field editor with type indicators, inline NULL handling, and syntax-highlighted nested JSON. Edit values without writing console code. • LocalStorage, SessionStorage, Cookies, and Cache Storage browsers — view, add, edit, delete, and clear entries with the same grid UI. • Import and export — read and write NDJSON, CSV, SQL INSERT statements, and ZIP snapshots. Round-trips non-JSON types including Date, BigInt, Map, Set, Blob, and ArrayBuffer. • Snapshots and diffs — snapshot a store or whole database, then restore or diff against it later. Useful for verifying migrations and reproducing bugs. Built for • Frontend developers debugging IndexedDB-backed applications • Teams working on offline-first or PWA codebases • Anyone who needs to inspect, edit, or migrate data sitting in browser storage • Engineers tired of writing one-off console snippets to read or modify storage Privacy Everything runs locally on your machine. IdxBeaver makes no network requests: no analytics, no telemetry, no remote configuration. Your preferences, query history, and saved queries are stored using chrome.storage.local and never leave your browser.
