EZ Seed Finder vs SeedLander

EZ Seed Finder searches for Minecraft Java Edition seeds through a graphical interface or the ezsf command-line tool. Its .ezsf criteria language supports random or sequential scans, seed ranges, thread counts and result limits. A search can combine checks across the Overworld, Nether and End, including structures, biomes, spawn conditions, strongholds, bastion variants, distances between structures, mobs and chest loot. Structure options include villages, temples, mansions, monuments, ruined portals, ancient cities and trial chambers. Results appear in a table, and double-clicking one copies its seed. The search engine uses cubiomes through a vendored cubiomespi-fork build. The package runs on Linux, macOS and Windows and requires Python 3.11 or later; the GUI also requires tkinter. Windows installation may require Microsoft C++ Build Tools to compile the native library. Stronghold and terrain results have accuracy limits: full-stronghold checks use a ring-1 proximity heuristic, while terrain and height checks are experimental biome-based proxies rather than true surface-noise analysis. The project is MIT-licensed and free, with no map preview.

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.
