Chunkmap review
A free, focused viewer for rendering Minecraft region files across all three dimensions.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Chunkmap is an open-source tool for generating top-down 2D maps from Minecraft world region files. It is aimed at players, administrators, and technical users who want to inspect their own worlds without relying on a live server connection. Region files in .mca format can be uploaded to its browser-based viewer, while the command-line interface provides another way to generate maps. Support covers the Overworld, Nether, and End, making it suitable for offline viewing across Minecraft's core dimensions.
Its main strength is rendering flexibility within a focused 2D workflow. Chunkmap offers texture, heightmap, biome, temperature, downfall, and inhabited render modes, so users can choose how world information is displayed. Map image merging is also available for combining rendered sections. The project is free and open source, with web and Windows availability. For users who prefer a lightweight region-file workflow rather than a server-connected map service, that combination keeps the tool's purpose clear.
Chunkmap is a better fit for offline inspection than for live world monitoring or collaborative server mapping. The project is marked beta and may not work as expected, so it suits users who can accept an evolving tool. Modded worlds and worlds generated before Minecraft 1.18 are unsupported, which narrows its compatibility. Choose Chunkmap for free, offline rendering across the Overworld, Nether, and End; choose an alternative if you need verified markers, server support, live updates, or broader world compatibility.
