Bedrock Viz vs Hex Fiend

Bedrock Viz parses Minecraft Bedrock Edition world files to create overview images and reports, and it can generate a browser-based viewer for exploring a world. The viewer covers Overworld and Nether layers, biomes, mobs and items, spawnable blocks, chunk boundaries, elevation shading, and distance measurement. It can browse 256 layers from bedrock to the build limit. Image outputs include world layers, biomes, block light, block height, and grass color; movie output is available for world layers and requires ffmpeg. The software is free and listed for Linux, macOS, web, and Windows. The README provides a Windows 10 download, supports macOS 10.15 and later through Homebrew, and directs Linux users to compile the source. Generated maps can be served locally with Docker and NGINX, or viewed offline. Running the program can change world files, so work from a backup. Locally opened viewers may lose some features because of browser restrictions, and slime chunk finding may be unreliable.

Hex Fiend is a free, open-source hex editor for macOS that can insert, delete, rearrange, and overwrite binary data. It can search large files and compare them while accounting for insertions and deletions. The editor does not keep files in memory or require a full file to be loaded. Its smart saving avoids rewriting unchanged portions and does not require temporary disk space. The maker says it can handle files as large as users can create and reports testing files up to 118 GB. A data inspector interprets values as signed or unsigned integers and floating-point numbers in big- or little-endian formats. Scripted binary templates visualize file structure, and an embeddable framework provides hex and data views under a permissive BSD-style license. The official site lists version 2.18.1 and requires macOS 10.14.6 or later. The Mac App Store distribution collects no data and makes no network requests; the direct-download distribution checks for updates without collecting or storing user data. Hex Fiend is notarized for macOS 10.14 and later.
