WKT Studio vs geojson.io: Which Web GIS Tool is Best for Developers?
By Fidel Roman
For over a decade, geojson.io has been the default web sandbox for quickly drawing and tweaking GeoJSON primitives. However, as modern GIS workflows increasingly center around PostGIS databases, Shapely scripts, and multi-layer projects, developers run into format limitations.
Direct Answer: Use
geojson.io if you only need a lightweight scratchpad for plain GeoJSON. Use WKT Studio when your workflow involves Well-Known Text (WKT), PostGIS SQL generation, Shapefile imports, spatial analysis (Buffer/Union), or a REST API.Feature Comparison
| Feature | WKT Studio | geojson.io |
|---|---|---|
| Native WKT Pasting & Export | ✓ Native | ✗ Plugin required |
| Import Shapefile (.shp + .dbf) | ✓ Native browser parser | Partial / manual zip |
| PostGIS SQL INSERT Export | ✓ 1-click SQL copy | ✗ None |
| Visual Attribute Table | ✓ Interactive spreadsheet | Raw JSON editor only |
| Spatial Analysis (Buffer / Union) | ✓ Built-in Turf.js tools | ✗ None |
| REST API Access | ✓ GET, POST, DELETE with API Key | ✗ None |
| Project Version History | ✓ 20 snapshots with rollback | ✗ None |
When to choose WKT Studio
If your day-to-day job includes querying Postgres with ST_AsText(), building spatial ETL pipelines, or delivering interactive map links to stakeholders, WKT Studio eliminates the friction of format conversions and desktop GIS dependencies.
