Minecraft tool turns your real neighborhood into a playable map

by

Arnis is a free tool that transforms actual places into Minecraft maps. It allows players to virtually explore their own neighborhoods, recreated block by block with accurate geographic information.

Arnis, created by Louis Erbkamm, builds incredibly detailed Minecraft worlds by using real-world data from OpenStreetMap and elevation maps. It began as a small project, but has become very popular, with almost 300,000 users creating custom worlds as of early 2026.

This tool creates maps showing roads, buildings, parks, and bodies of water. It uses elevation data from Amazon Web Services to build realistic terrain, letting Arnis accurately position real-world objects on the map instead of simply placing them on a flat surface.

A new open-source tool lets you turn any location in the real world into a playable Minecraft map. It uses data from OpenStreetMap to recreate your neighborhood, city, or even a single street, block by block. The tool is completely free to use and modify.

Arnis lets players explore real-world locations inside Minecraft

A major attraction of this tool is its ability to recreate familiar places. Users can easily search for their home address or define a specific area, and then quickly generate a playable version of their street or town. The tool doesn’t just randomly generate buildings – it uses actual map data to ensure the layout is as accurate as possible.

Arnis has become more capable over time. It started by creating smaller areas, but now it can produce highly detailed cities like New York and Las Vegas, and also realistic natural environments with varying heights and terrain.

The tool has been significantly enhanced with the latest updates. The Alpine update features better terrain creation and identification of land features, and now, with support for NASA elevation data, users can create incredibly large and detailed environments – everything from mountain ranges to landscapes resembling the Moon.

Arnis now works on more than just computers, including versions of Minecraft for consoles, phones, and virtual reality. Plus, with a tool called MapSmith, you can create maps directly in your web browser – no download needed!

As a fan, I’m really glad this project is staying totally free and open for anyone to use! You can download it on Windows, Mac, or Linux – it’s awesome that it works on all those platforms.
