Seed Map Pro vs SeedLander

Seed Map Pro maps Minecraft Java and Bedrock seeds, showing biomes, terrain, and structure locations across the Overworld, Nether, and End. Users can search by biome, structure, terrain height, or quad-structure clusters, then save seeds and place custom pins on maps. The free plan supports map rendering, biome and structure browsing, and seed search, with up to three saved seeds and ten pins per map. Plus adds estimated ore locations and previews of chest contents in major structures; these predictions are derived from the world seed and may differ from what appears in game. The app is described as native software for iPhone, iPad, and Mac. Its latest listed update supports Java 26.2 and Bedrock 26.30–26.40. Plus costs $3.99 a month or $24.99 a year. The developer describes the app as an independent project with no ads or tracking. App Store disclosures say identifiers, usage data, and diagnostics may be collected without being linked to the user. Seed Map Pro says it is not an official Minecraft app and is not approved by or associated with Mojang 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.
