Comprehensive GIS Capabilities
The Modern Online GIS Software for Web & Browser GIS
Engineered as a high-performance online GIS tool and large GIS file viewer. Everything runs client-side with zero installation.
Large Shapefile Viewer (No Upload)
Functions as an ultra-fast online shapefile viewer and large shapefile viewer. Drop zipped Shapefiles (.shp, .dbf, .prj) or standalone .shp files up to 2GB+. Parse and stream without uploading to a remote server.
Online GeoJSON Editor & Viewer
A comprehensive online GeoJSON editor and GeoJSON viewer. Inspect feature properties, edit layer symbology colors, adjust line widths, filter attribute tables, and export features with sub-millisecond responsiveness.
GeoParquet Viewer & Columnar GIS
Next-generation GeoParquet viewer and GIS file viewer. Mount Apache Parquet and FlatGeobuf files straight into DuckDB-WASM virtual memory for columnar spatial queries and instant viewport rendering.
3D GIS Viewer & Geospatial Data Viewer
An interactive 3D GIS viewer and online geospatial data viewer. Renders geometries directly on a WebGL 3D globe via Deck.gl GPU vertex buffers, bypassing CPU tiling bottlenecks at 60 FPS.
Browser GIS with DuckDB-WASM SQL
Enterprise online GIS software and browser GIS. Automatically creates RTREE(geom) spatial indices for sub-millisecond spatial SQL filtering (ST_Intersects) without taxing your device's main thread.
Web GIS & Coordinate Reprojection
Modern web GIS and online GIS viewer featuring On-The-Fly (OTF) reprojection using Proj4. Automatically converts projected coordinates (UTM, British National Grid, State Plane) into WGS 84 for seamless globe overlay.

How This Browser GIS Software Operates
A look inside the client-side architecture powering our online GIS map editor and GIS data viewer.
Zero-Upload Ingestion
Files are loaded directly into browser Web Workers via Transferable ArrayBuffers, ensuring a true GIS viewer no upload experience.
DuckDB-WASM RTREE
Virtual tables are built in WebAssembly. Spatial indices (USING RTREE) accelerate bounding-box queries for our large GIS file viewer.
On-The-Fly CRS
Projected coordinates in UTM, British National Grid, or State Plane are reprojected to WGS 84 in real time by our web GIS engine.
Deck.gl 3D WebGL
GPU vertex shaders render polygons and points at 60 FPS, making this the most responsive 3D GIS viewer online.
Universal GIS File Viewer
Supported GIS & Geospatial Data Formats
No installation, no plugins, and no file conversion. Our online geospatial data viewer handles all standard spatial files.

Frequently Asked Questions
Online GIS Tool & Viewer FAQ
What is the best free online GIS tool and online shapefile viewer?
Infryne TechWorks Spatial Studio is the leading free online GIS tool and online shapefile viewer. Built on Next.js, DuckDB-WASM, and Deck.gl, it lets GIS professionals view, edit, and inspect large Shapefiles, GeoJSON, and GeoParquet files in any modern web browser without installing desktop software.
How does this online GIS map editor view large shapefiles with no upload?
As a true GIS viewer no upload solution, all decompression (via WebAssembly fflate) and spatial indexing take place in sandboxed Web Workers. Your data is mounted directly into a DuckDB-WASM virtual file system on your machine, making it an extraordinarily secure large shapefile viewer for proprietary datasets.
Can I use this as an online GeoJSON editor and GeoJSON viewer?
Yes. You can use it as an online GeoJSON editor and GeoJSON viewer to visualize points, linestrings, and complex polygons. You can customize layer colors, opacity, point radii, and stroke widths, inspect raw attributes in an interactive SQL table, and export binary FlatGeobuf files.
Does this 3D GIS viewer support GeoParquet and live ArcGIS REST services?
Yes. As an advanced 3D GIS viewer and GeoParquet viewer, it connects directly to Apache Parquet files, FlatGeobuf files, and live ArcGIS REST endpoints (FeatureServer and MapServer) without requiring middleware or server proxies.
