Feed the Mods Minecraft Seed Map vs RepeaterFinder

Feed the Mods Minecraft Seed Map is a free web tool for exploring worlds generated from Minecraft seeds. It maps biomes, structures, slime chunks, and coordinates using separate Java and Bedrock generation rules. The map combines more than 30 structure finders, including villages, strongholds, ancient cities, fortresses, bastions, and End cities. It advertises support for 14+ Java versions, Bedrock, Large Biomes, and the Overworld, Nether, and End. A live cursor readout shows biome information, while coordinate tools copy X/Z values or a /tp command. Signed-in users can sync markers, notes, and explored structures across devices and create read-only sharing links; signed-out users keep markers on their device. The map preserves views in links and calculates generation from seed settings rather than editing saves. It targets vanilla content, not ores or modded structures. Custom generation, mods, datapacks, or upgraded explored chunks can make results differ from the game.
