About IdxBeaver

  • What is IdxBeaver?
    IdxBeaver is a Chrome DevTools extension that turns the Application panel into a real database client for browser storage. You get a dense data grid, MongoDB-style queries with index-aware planning, a row inspector, schema inference, and import/export across JSON, NDJSON, CSV, SQL, and ZIP — for IndexedDB, LocalStorage, SessionStorage, Cookies, and Cache Storage.
  • Which browsers does it support?
    Any Chromium-based browser on version 110 or newer with Manifest V3 support — Chrome, Edge, Brave, Arc, and Opera all work. Firefox and Safari are not currently supported because their devtools extension APIs differ.
  • Where do I install it?
    From the Chrome Web Store. If you prefer to load it unpacked, every release ships a .zip on GitHub Releases.

How it compares

  • How is IdxBeaver different from Chrome's built-in Application panel?
    Chrome’s panel can list databases and dump records, but it has no filtering, no schema awareness, no bulk edits, no query history, and no exports that survive a refresh. IdxBeaver gives you all of that plus a query language, multi-tab editor, undo/redo for grid edits, and a Structure view that shows the inferred schema for each store. There’s a full breakdown on the comparison page.
  • Can I write SQL queries?
    IdxBeaver ships a MongoDB-style JSON query language with $eq, $gte, $in, compound filters, projections, sorts, and limits. The query planner uses an IDB index when one matches, with an in-memory fallback for compound operators. Plain SQL is on the roadmap.
  • Does it support multiple frames?
    Yes. IndexedDB is partitioned per frame origin. IdxBeaver scans every scriptable frame on the page in parallel and merges the results, so iframe-heavy apps surface their full storage footprint instead of just the top frame.

Privacy & licensing

  • Does IdxBeaver send my data anywhere?
    No. IdxBeaver runs entirely in your browser. There is no telemetry, no auth, no servers — and no account to create. Inspected storage is read on demand only on the page you have DevTools open against. See the privacy policy for the full list.
  • Is it free? What's the license?
    Free, and MIT-licensed. The full source is on GitHub — fork it, audit it, run a build of your own.
  • Where can I report bugs or request features?
    Open an issue on GitHub. Reproductions with the affected origin and store name help most.
