McMeddon's Worlds vs MinecraftMaps.com

McMeddon's Worlds is a library of custom Minecraft worlds, with data and a browser-based 3D explorer for surveying terrain before downloading. Visitors can fly over landscapes in the browser without installing software. The collection spans survival, creative, single-biome, civilization, SkyBlock, seasonal, community, and test worlds; multiplayer maps and search filters are available. Downloads are for Java Edition, while Bedrock files are limited to worlds explicitly marked as compatible. The maker describes building terrain with World Machine, adding trees and structures in Minecraft, then assembling and exporting maps with WorldPainter. Some world files are free; others require the indicated Patreon membership. Small survival worlds are listed at $5 a month and large ones at $9 a month. Worlds downloaded during membership remain playable after it ends, but further downloads stop. Browser utilities include a Java vault fixer, a loot chest command generator, and a searchable world contents finder. Bedrock conversions may have rough edges, empty chests, or missing living villagers. Worlds are generally under a license requiring attribution and barring as-is resale or redistribution.
