geojson.io

geojson.io is a popular open-source web-based tool designed for rapid creation, visualization, and editing of geospatial data. It was originally created in 2013 by Tom MacWright while he was an engineer at Mapbox. The tool serves as a lightweight interface for developers and GIS professionals to manipulate GeoJSON data, providing a dual-view interface with a live map and a code editor.

While the project started as a personal endeavor, it was later integrated into the Mapbox ecosystem and is currently hosted in a Mapbox-managed repository on GitHub. As an open-source project, its code is available under the ISC License, allowing for broad community contribution. Today, it remains a staple in the web mapping community and is officially maintained and powered by Mapbox, utilizing Mapbox's GL JS library for its rendering capabilities.

The project is headquartered in the United States, as Mapbox is based in San Francisco and Washington, D.C. Although it is a digital product, its "manufacturing" context refers to its development and hosting origins within the U.S. technology sector.
