From database output to a map you can ship.

WKT Studio keeps the developer workflow intact: inspect the exact geometry, make the change, and choose the output your stack needs.

  1. Bring geometry in

    Paste WKT from PostGIS or Shapely, or import GeoJSON, Shapefile, CSV, and Excel data.

    ST_AsText(geom) → WKT · GeoJSON · SHP

  2. Verify it on the map

    Inspect attributes, edit vertices, style layers, and run Buffer or Union without installing desktop GIS.

  3. Ship the result

    Export PostGIS SQL, GeoJSON, KML, or CSV. Share a read-only map, embed it, or use the project API.

Questions before you paste?

What is WKT Studio?

WKT Studio is a full-featured GIS map editor and spatial data platform for developers. It lets you paste WKT geometry, import GeoJSON/Shapefiles, run spatial analysis (Buffer, Union, Subtract), export PostGIS SQL, access a REST API, and collaborate with your team — all from the browser.

What file formats can I import?

WKT Studio supports GeoJSON (.geojson), Shapefile (.shp + .dbf), CSV with a WKT column, and CSV with latitude/longitude columns. All imports create a new layer in your project.

What WKT geometry types are supported?

WKT Studio supports the full OGC WKT standard: POINT, LINESTRING, POLYGON, MULTIPOINT, MULTILINESTRING, MULTIPOLYGON, and GEOMETRYCOLLECTION.

Can I use WKT Studio with PostGIS?

Yes. Run SELECT ST_AsText(your_geom) in PostgreSQL/PostGIS, copy the result, and paste it into WKT Studio. You can also use the REST API to push geometries directly from your SQL pipeline.

What is the REST API?

Every project exposes GET, POST, and DELETE endpoints. You can list features, add new ones, or remove them programmatically using a Bearer API key generated in your account Settings. See the API Docs for curl examples and rate limits by plan.

Is WKT Studio free?

Yes. Free gives you 3 projects, 2 layers, up to 50 features per layer, the full spatial analysis toolkit (Buffer, Union, Intersect, Difference), public read-only sharing and 100 API calls per month. Pro adds unlimited projects, 5,000 features per layer, KML export, styles, history, embeds and active collaboration.

Your geometry is already there. Make it visible.

Paste WKT and see the result before changing a line of code.
