Bedrock Viz

Bedrock Viz is a free tool for visualizing and inspecting Minecraft Bedrock Edition worlds. It parses world files to produce overview images and reports, and can generate a browser-based viewer for exploring the Overworld and Nether. The viewer covers 256 layers from bedrock to the build limit and includes biomes, mobs and items, spawnable blocks, chunk boundaries, elevation shading, and distance measurement.

It can create images of world layers, biomes, block light, block height, and grass color. It can also make movies of world layers across that vertical range, though movie creation requires ffmpeg. Generated maps can be viewed offline or served locally with Docker and NGINX. The project is GPL-2.0 licensed and supports Windows, macOS, Linux, and web viewing. The README provides a Windows 10 zip, supports macOS 10.15 and later through Homebrew, and directs Linux users to compile the source.

Running Bedrock Viz can change world files, so use a backup copy. Browser restrictions may disable block details on hover or elevation shading when opening a viewer as a local file; Firefox works best in that situation. Slime chunk finding may be unreliable.

Bedrock Viz provides detailed maps, reports, and image outputs for Minecraft Bedrock Edition worlds. Work from a backup, and account for local-browser restrictions and the caveat around slime chunk finding.

It suits people who want to inspect and map Minecraft Bedrock Edition worlds, including their Overworld and Nether layers. It is also useful for users who want generated images or local browser-based maps and can follow the installation instructions for their platform.

Bedrock Viz turns Minecraft Bedrock Edition world files into maps, reports, and images. It best suits players who want to inspect a saved world offline; its broad set of views is useful, but changing files and browser-dependent features make backup and setup care essential.

Overview

This free, GPL-2.0 tool parses Bedrock worlds and produces a browser viewer alongside reports and visual outputs. Its 2D maps cover 256 layers of the Overworld and Nether, from bedrock to the build limit, and can be viewed offline. That makes it a focused option for studying a local save rather than a hosted map service.

Bedrock Viz can change world files while running, so use a backup rather than your only save. When serving generated maps, keep sensitive files out of the served output. These precautions are central to using the tool safely, not optional housekeeping.

Key features

Layered world inspection

The viewer offers biome, mob, item, and spawnable-block views, with chunk boundaries, elevation shading, and distance measurement. Those tools help players inspect terrain and locate world features. Slime chunk finding may be unreliable, however; confirm that slimes spawn before investing in a build based on its results.

Opening the viewer as a local file can restrict features, including block details on hover and elevation overlays in Chrome. Firefox works best for this local-file use, though browser restrictions remain a practical consideration.

Images, movies, and deployment

Image exports cover world layers, biomes, block light, block height, and grass color. Movies can show world layers from bedrock to the build limit, but require ffmpeg. Generated maps can also be served locally through NGINX in Docker, a useful route for users comfortable with that setup; the viewer itself is based on OpenLayers.

Pricing

Free — free. The free plan includes Minecraft Bedrock Edition world support under the GPL-2.0 license, with no paid tier or quota described. It is the natural fit for individual players who can work with the installation and local-serving options. The trade-off is that setup and safe file handling are the user's responsibility.

Platforms

Bedrock Viz supports Linux, macOS, Windows, and the web viewer. Windows users can download a Windows 10 zip containing bedrock-viz.exe; macOS 10.15 and later are supported through Homebrew. Linux users are directed to download and compile the source, which is a less convenient path for anyone expecting a ready-to-run package.

The browser viewer supports offline viewing, but a locally opened file may lose some features depending on the browser. Android world backups can be brought into the workflow with DropSync and Dropbox, though that method has only been lightly tested and should be approached cautiously.

Who it's for

Choose Bedrock Viz if you want detailed maps and exports from your own Minecraft Bedrock Edition world and are willing to protect the save with backups. It is less suitable if you need dependable slime-chunk guidance, want a frictionless Linux install, or expect every viewer feature to work when opened locally in any browser.

Pros and cons

• Pro: Broad inspection across both dimensions and 256 layers helps examine terrain without relying on a hosted service.
• Pro: Maps, multiple image types, and optional movies serve different ways of reviewing or sharing a world.
• Pro: Free and offline viewing avoid a recurring plan cost or a requirement to use a hosted viewer.
• Con: The program can change world files, so working from a backup is important.
• Con: Local browser restrictions can disable hover details and elevation overlays, particularly in Chrome.
• Con: Slime-chunk results may be unreliable, and Linux installation requires compiling source.

Alternatives

BedrockMap is worth considering if you want a web option across mobile and desktop platforms; its free plan limits users to one world upload, a 1500x1500-block render area, two renders per day, three zoom levels, and public sharing links.

BlueMap is free for Java Edition worlds, with Java 25+ required for server plugin or mod use and Java 21+ documented for its standalone CLI; it is not the Bedrock-world choice.

Mapcrafter is free for users working with Anvil world format and Minecraft 1.6 resource packs, rather than Bedrock saves.

Verdict

Bedrock Viz is a strong fit for Bedrock players who want offline, layer-by-layer world inspection plus image and movie exports without a subscription. Its range of views is the main reason to choose it; the need to protect saves, browser limits, and uncertain slime-chunk findings are good reasons to look elsewhere if reliability or convenience matters more.
