Bedrock Viz vs GNU hexedit

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.

GNU hexedit is a free Linux terminal program for viewing and editing file contents as hexadecimal values or ASCII text. It can read a device piece at a time, search forward or backward for strings in either representation, and save edits. Selection commands allow marking, copying, pasting, saving a copied region to another file, and filling a selected area with a string. The --sector option displays whole sectors and makes scrolling advance sector by sector. Keyboard commands control the terminal interface; --color works only when supported by the operating system. Changes remain in memory until saved, so large fill operations may trigger a warning. Read-only files cannot be changed and are reported as non-writable. The author describes hexedit as open source under the GNU General Public License. The maker page links to source archive 1.6, while Git builds use ./autogen.sh && ./configure && make. It supports disk editing but has no binary comparison, templates, scripting, or plugins.
