What EZ Seed Finder is

EZ Seed Finder is a free, MIT-licensed tool for finding Minecraft Java Edition seeds on Linux, macOS, and Windows. It uses cubiomes, through a vendored cubiomespi-fork build, to search for structures and biome data. Its .ezsf criteria language lets a search combine conditions for the Overworld, Nether, and End, with random or sequential scanning, seed ranges, thread counts, and result limits. Searches can cover structures including villages, temples, mansions, monuments, ruined portals, ancient cities, and trial chambers; spawn and biome conditions; strongholds; bastion types; structure spacing; mob suitability; and version-aware chest loot. Ruined portals can also be filtered by frame criteria. Results appear in a table, and double-clicking one copies its seed. The package includes the ezsf command-line interface for headless searches as well as a graphical interface. It requires Python 3.11 or later, and the GUI requires tkinter. Windows installation may require Microsoft C++ Build Tools and the Desktop development with C++ workload to compile the native library. Terrain and height checks are experimental biome-based proxies, not true surface-noise analysis. The full-stronghold option also uses a ring-1 proximity heuristic because cubiomes does not model portal-room layout.

Who it suits

EZ Seed Finder suits Minecraft Java Edition players who want to search seeds by combining structure, biome, spawn, or loot criteria. It can also suit users who prefer headless searches through a command-line interface or need to search across multiple dimensions.

What it does well

Combines Overworld, Nether, and End criteria in one search.
Supports random and sequential scans, seed ranges, thread counts, and result limits.
Searches structures, biomes, spawn conditions, strongholds, bastions, mobs, and chest loot.
Table results can be copied by double-clicking.
Includes both a GUI and a headless command-line interface.
Free and licensed under MIT.

What to know first

Requires Python 3.11 or later.
The GUI requires tkinter.
Windows installation may require Microsoft C++ Build Tools.
Terrain checks are experimental proxies, and full-stronghold checks use a proximity heuristic.

Getting started

Open the project website on GitHub.
Install Python 3.11 or later.
Install the package with `pip install ezseedfinder`.
For the graphical interface, make sure tkinter is available.
On Windows, install Microsoft C++ Build Tools with the Desktop development with C++ workload if needed for native compilation.
Use the GUI or the ezsf command-line interface to search.

Verdict

Choose EZ Seed Finder if you want a free desktop or command-line way to filter Minecraft Java Edition seeds using criteria across all three dimensions. Look elsewhere if you need a map preview or terrain checks based on true surface noise; its terrain checks are experimental proxies.

Questions

Is EZ Seed Finder free?

Yes. Its pricing model is free, and the project is open source under the MIT license.

Which operating systems does it support?

The package is classified for Linux, macOS, and Windows.

What does it require?

It requires Python 3.11 or later. The graphical interface also requires tkinter.

Does it have a command-line interface?

Yes. The ezsf interface supports headless searches.

How accurate are its terrain and stronghold checks?

Terrain and height checks use experimental biome-based proxies rather than true surface noise. The full-stronghold option uses a ring-1 proximity heuristic because cubiomes does not simulate portal-room layout.

Does it show a map preview?

No. The listed interface displays results in a table, and double-clicking a result copies its seed.
