RepeaterFinder

What RepeaterFinder is

RepeaterFinder is free, open-source software for finding Minecraft Java Edition world seeds with repeating structures near spawn. It scans a configurable chunk radius for selected Overworld structures and checks candidate positions for biome viability. It identifies repeating positions along the X or Z axis, requiring at least four structures by default. Users can search random seeds in hunt mode or analyze a known seed with single scan mode. The project provides a command-line interface and a Tkinter graphical interface with real-time updates. Settings include Minecraft version, structure type, scan radius, minimum structure count, and periodicity threshold. Qualifying seeds and coordinates can be exported to JSON or CSV, while structure positions can be plotted to PNG. The README describes support for Minecraft Java versions 1.18–1.21+ and installation through pip on Windows, macOS, and Linux. Python 3.11 or later is required, along with dependencies including cubiomespi, NumPy, Matplotlib, and tqdm. The project is licensed under the MIT License. The README notes that support for additional Minecraft versions depends on adding version enums as cubiomespi updates.

Who it suits

RepeaterFinder suits Minecraft Java Edition players who want to locate seeds with repeating structures near spawn. It offers both command-line and graphical interfaces for searches or scans.

Limits

The default repeat detector requires at least four structures. Support for additional Minecraft versions depends on adding version enums as cubiomespi is updated.

Getting started

1. Open the RepeaterFinder GitHub website
2. Install Python 3.11 or later
3. Create and activate a virtual environment for your operating system
4. Install the project and named dependencies with pip
5. Choose hunt mode or single scan mode
6. Set the Minecraft version, structures, radius, minimum count, and periodicity threshold

Verdict

RepeaterFinder offers configurable structure searches, two operating modes, and export options for Minecraft Java seeds. It requires Python 3.11 or later, and additional version support depends on updates to cubiomespi.
