Ezseed Minecraft Seed Finder vs SeedLander

Ezseed Minecraft Seed Finder is a free browser tool for locating Minecraft worlds that match chosen structures and biomes. Structure filters can target mapped structures, require a count from 1 to 10, and set a radius and center point. Biome filters look for any biome within a specified radius, and multiple conditions can be combined so every one must match. The finder supports Java 1.20 through 26.2 and Bedrock up to 26.30. Each matching result opens on a full seed map for inspection before play, and the map state in the URL can be bookmarked or shared. Searches run in the browser using the selected edition's world-generation rules. Seed calculations run locally through cubiomes WebAssembly; Ezseed says seeds are never uploaded and the tool works offline once loaded. The listed free plan requires no download or account. Results may be incomplete, approximate, outdated, or wrong for some versions, coordinates, devices, or edge cases. Ezseed describes the utility as fan-made and says it is not approved by or associated with Mojang Studios or Microsoft.

SeedLander is a browser-based toolkit for analysing Minecraft seeds in Java Edition and Bedrock Edition, including Java Large Biomes. Its tools cover biome maps, structure searches, ore predictions, slime chunk calculations, portal management, and team collaboration. The structure finder covers 25+ types and provides coordinates for places such as villages, strongholds, temples, mansions, and monuments. SeedLander states that most structure results on Java and Bedrock are 97%+ accurate, while cautioning that they are predictions rather than guarantees. The tools run in the browser using WebAssembly, and seeds are not sent to SeedLander servers for processing. Map, finder, and account pages support touch use 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. A Team add-on costs £2.99 per month per world on top of Premium.
