Arnis is a desktop application that generates Minecraft Java Edition, Bedrock Edition, and Luanti worlds representing real-world locations with geographic accuracy.
The tool solves the problem of manually recreating real-world geography in Minecraft by automating the conversion of geospatial data into game worlds. It fetches terrain elevation data and building information from OpenStreetMap via the Overpass API, then processes this geographic data through a modular pipeline to generate detailed Minecraft structures and landscapes. Users select a rectangular area on a map through a graphical interface, choose their target Minecraft world, customize settings like world scale and building interiors, and initiate generation with a single click.
Arnis suits players and creators who want accurate representations of real locations—their hometowns, cities, or natural landscapes—without manual construction. The project emphasizes modularity, performance, and cross-platform support on Windows, macOS, and Linux. For those needing mobile generation or larger map sizes without installation, the README mentions MapSmith as a browser-based alternative.
Almost all open issues are raised by outside users rather than the core team, indicating a substantial base of adopters using the tool in practice. Maintainers typically respond to new issues and pull requests within a day. Work in the issue tracker is dominated by bug reports, feature requests, and discussions.
