The record

Purpose: mcseedmap.net is an online Minecraft seed map viewer and seed finder.
Map output: It displays a browseable map for a seed with biomes, terrain estimation, and structures such as villages and ocean monuments.
Seed search: The site can find seeds containing specified biomes and structures within a given area.
Game editions: The site supports Minecraft Java and Bedrock editions, including Java 26.3 and Bedrock 26.50.
Map settings: Map settings include terrain estimation, contour lines, underground biomes, selectable Y levels, grids, binary coordinates, chunk coordinates, zoom snapping, and floating tooltips.
Datapack limit: The datapack mapper currently supports only Java Edition 1.20.x and 1.21.x overworld mapping.
Accuracy: Biomes are described as pretty accurate, structure positions are accurate within a few blocks but can be missing or generated differently, and spawn positions can be completely wrong for some seeds.
Browser requirement: The site uses WebAssembly, which is unsupported by older browsers, so it recommends an up-to-date browser.
Performance limit: The maker says browser execution makes speed a major limiting factor for advanced seed-finder searches.
Security service: mcseedmap.net says it is protected and accelerated by Cloudflare services.
Privacy collection: The privacy policy says the site may automatically collect IP address, browser type, operating system, referring website, pages visited, and visit dates and times for analytics and debugging.
Advertising and analytics: The privacy policy says the site uses Google Analytics and may use Google AdSense cookies for traffic analysis and relevant advertising.
Support: Privacy questions can be sent to the email address listed on the privacy policy page.
