Bedrock Pattern Finder
by slashThree
Bedrock Pattern Finder is a client-side Fabric tool that calculates world coordinates where the bedrock floor matches a chosen pattern, given a world seed.
What it does
Players open the search screen with the command bedrockfind or the bedrockfind gui command, enter a world seed and a chunk search radius, and the mod lists coordinates whose bedrock layout fits the pattern. It uses the modern generation math, so results follow the current world generator.
The tool suits recovering lost coordinates, checking a seed, or locating a spot where only the bedrock layout is visible. It runs entirely on the client, so it works on multiplayer servers as long as the player knows the world seed. Fabric Loader and Fabric API (recommended) are required, and the mod is published for Minecraft 1.21 and later, with files for 1.21 – 26.2 across 16 release versions.
The mod is released under All rights reserved and is not open source. The author states it is provided without warranty, and players who use it bear the risk of server bans, account actions or data loss. Check that the server permits such tools before using it.
Key features
16x16 pattern grid
A grid screen lets the player click cells to recreate the bedrock pattern they saw in the world.
Multithreaded search
Chunks are scanned in the background on several threads, though very large radii of 1000 or more chunks can still cause frame drops while a search runs.
Saved inputs
The last entered seed and search radius are stored and restored in the next session.
Absolute coordinates
Each match is reported as absolute world coordinates matching the bedrock floor pattern.

How it compares
Stronghold Finder (One Eye Updated) is a Fabric client-side mod for 26.2 – 26.3, open source under the MIT License, so it locates strongholds rather than bedrock patterns. In Game Calculator is a Fabric mod for 1.21.6 – 26.3 where the client is required and the server is optional, released under CC0 1.0 Universal and not open source. Bedrocks Blocks runs on client and server together for 1.21.11 only, under the MIT License and not open source, so it needs both sides installed.
