FIG 0.3 · Query

MongoDB-style queries.Index-aware plans.

One JSON document — store · filter · project · sort · limit. Equality and range filters are served from IndexedDB indexes automatically; the plan is visible live.

FIG 0.4 · More

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.So we built the tool we wanted.
