What SeedLander is

SeedLander is a browser toolkit for analysing Minecraft seeds, with biome maps, structure finding, ore prediction, slime chunk calculations, portal management, and team collaboration. It supports Java Edition, including Java Large Biomes, and Bedrock Edition. The structure finder covers more than 25 structure types and gives coordinates for places such as villages, strongholds, temples, mansions, and monuments. SeedLander reports 97%+ accuracy for most structures on both editions, but results are predictions rather than guarantees. Its tools run in the browser using WebAssembly, and seeds are not sent to SeedLander servers for processing. The map, finders, and account pages are touch-friendly on phones and tablets; a dedicated mobile app is on the roadmap. The free Basic plan includes all seed tools, 10 custom markers, and three saved portal pairs. Premium costs £1.99 per month per world and adds unlimited markers and portals, ore tracking, structure completion tracking, notes, and an activity log. The Team add-on costs £2.99 per month per world on top of Premium and provides unlimited team members.
