From raw geometry to a shareable, styled map in minutes.
Run ST_AsText() in PostGIS, call .wkt on a Shapely geometry, or import GeoJSON, Shapefile, CSV, or Excel. Any source works.
SELECT ST_AsText(geom) FROM parcels;Draw new features, run Buffer or Union, edit the Attribute Table, and style each layer with custom colors and opacity.
Buffer(500m) · Union · Subtract · StyleExport as CSV, KML, GeoJSON, or PostGIS SQL. Or push features programmatically via the REST API with your API key.
POST /api/v1/projects/{id}/featuresMake the project public, embed as an iframe, or invite collaborators. Add comments to specific features and resolve them as a team.

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.
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.
WKT Studio supports the full OGC WKT standard: POINT, LINESTRING, POLYGON, MULTIPOINT, MULTILINESTRING, MULTIPOLYGON, and GEOMETRYCOLLECTION.
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.
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.
Yes. Free gives you 3 projects, 2 layers, up to 50 features per layer, public read-only sharing and 100 API calls per month. Pro adds unlimited projects, 5,000 features per layer, KML export, spatial analysis, styles, history, embeds and active collaboration.
