Everything a real database client has.
Minus the connection string.
Row inspector
Type-aware editor with NULL handling and a syntax-highlighted JSON tree.
Schema inference
Samples 500 rows per store. Exports to TypeScript or Dexie in one click.
Snapshots & diffs
Capture state, diff later. Field-level add / remove / change, one-click restore.
Bulk import / export
NDJSON, CSV, SQL INSERT, ZIP. Non-JSON types round-trip losslessly.
The Application panel treats browser storage as an afterthought.Notes from the maintainer
