QueryDeck for Spatial App Developers

QueryDeck is a native macOS database client built for spatial app developers. Read spatial data without leaving your database client.

You build apps with geometry columns: delivery zones, courier paths, coverage areas, store locations. Most Mac database clients give you coordinates as text at best. None render the actual shape on a map. QueryDeck previews every spatial cell on a native MapKit overlay so you can verify a polygon without leaving the result grid.

01Sound familiar?
×

Native Mac clients surface geometry as text at best. Coordinates, not shapes. You still open a browser viewer to see what a polygon actually looks like.

×

Postico displays PostGIS columns as EWKT text only. Coordinates, no shape.

×

TablePlus has a hover preview, but it is buried in a popup and lacks polygon-with-hole and multi-geometry rendering.

×

DBeaver Community has a Leaflet map viewer, but it is Java and Eclipse, not native macOS.

×

QGIS is a full GIS application, not a database client. Overkill for a developer who just wants to verify a row.

×

Pasting WKB hex (or even WKT) into gis.tools or a browser viewer is the workflow nobody admits to.

02How QueryDeck helps
✓

Geometry and geography columns decode to readable WKT (SRID=4326;POINT(4.35 50.84)) directly in the result grid.

✓

Double-click any spatial cell for a native MapKit overlay. Points, linestrings, polygons, multi-geometries, geometry collections, polygons with holes — all handled.

✓

Works in three places: SQL query tab, table browser, and notebook SQL cell.

✓

Built on Apple Silicon with Swift and AppKit. No Java VM, no web view, no Leaflet tiles.

✓

Same client also detects your Drizzle, Prisma, or TypeORM project and connects with one CLI command.

✓

Pre-filter discards non-spatial text so unknown columns are never mis-decoded.

03A day with QueryDeck
01

Open your delivery-zones project: `qdeck .` detects the ORM, connects to PostgreSQL.

02

Query: `SELECT id, name, area FROM delivery_zones;` — the area column shows readable WKT.

03

Double-click any area row. MapKit popover renders the polygon over Apple Maps.

04

Open the customer_addresses table in the browser, double-click a point cell to verify the coordinate.

05

Create a notebook to document the spatial fix, SQL cell + Markdown notes + inline map preview.

06

Export the notebook to PDF for the PR review.
