Bedrock Viz vs Bless

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.

Bless is a free binary editor for editing files as sequences of bytes. It supports multilevel undo and redo, customizable data views, multiple tabs, and fast find and replace. The project highlights efficient handling of large data files and raw disk editing, with search and save operations running in multiple threads. Bless exports to text and HTML, while plugins can add other export formats and extend the editor. It is written in C# with Gtk# bindings for GTK+ and distributed under the GNU General Public License, version 2 or later. GNU/Linux is the main target; listed supported platforms are Linux and Windows, and the README says it should also run on *BSD, Solaris, and Win32. Building the current version requires GTK+, a Mono/.NET runtime and C# compiler, Gtk# bindings, pkg-config, and Meson. The GitHub releases page has no releases, and the README provides source-build instructions. NEWS lists version 0.6.3 dated 2020-10-11. Saving a changed-size file under the same name requires temporary space for both files; same-size files save in place.
