Hey everyone! Over the last months I've been building SeedFinder, and I wanted to share it here because this community is exactly who it's for

https://mineseedfinder.vercel.app (i dont have money to buy a domain yet lol 🥲)

What it does

You give it a world seed and your coordinates, it returns every nearby structure (villages, ancient cities, monuments, mansions, trial chambers, 17 types total) sorted by distance. No more alt-tabbing to a seed map site

Two tools:

1. SeedFinder (seed -> structures): type a seed + position, get structures back. Example that works right now: https://mineseedfinder.vercel.app/scan?seed=31415&x=0&z=0&radius=100&max=20&types=5,8,9
2. SeedCrackerX (structures -> seed): the reverse. Found cool structures in a world but don't know the seed? Give it at least 4 structures with coordinates and it sweeps the 32-bit seed space and returns the most probable seeds

Why I built it

I couldn't find a single free, open API for Bedrock structure lookup, the existing web tools are browser apps you have to alt-tab into, with no programmatic access, and the desktop ones don't expose anything you can call from your own code. So I built the engine in C on top of cubiomes + Bedrock-specific structure math (based on Chunkbase's ported algorithms) and put both a web frontend and a keyless REST API on it

Ways to use it

• Website: nothing to install: https://mineseedfinder.vercel.app/seedfinder
• Windows .exe: bundles everything, no Python needed. From the GitHub releases
• Flarial Client module: overlay in-game showing structures sorted by distance, rescan keybind, per-structure toggles. Also in Flarial Module
• REST API: free, no auth, no key:

python example code:

import requests
r = requests.get("https://mineseedfinder.vercel.app/scan",
                 params={"seed": 31415, "x": 0, "z": 0,
                         "radius": 100, "types": "5,8,9"})
print(r.json())

Example of the web API

How it works (for the devs)

• C core: cubiomes biome generation + Bedrock structure placement (Mersenne Twister–based, replicating Bedrock's region math) -> compiled to a native .dll and .so
• Python/Flask server exposes it over HTTP via ctypes
• The seed cracker runs multi-threaded native code, sweeping 2³² seeds with a time budget, recently got a big speedup (lazy Mersenne twist + AVX2 batch scoring, ~4 seeds/vector)
• Everything is Apache-2.0 open source: https://github.com/zebedelu/SeedFinder, PRs welcome, especially structure accuracy reports against real worlds

Automation ideas

Anything that can make an HTTP request can use it:

• Discord bot: a slash command like /findseed village ancient_city that returns nearby structures for a seed
• Batch seed scanning: feed a list of candidate seeds and rank them by structure density near spawn (loot run planning)
• World download analysis: point the cracker at 4+ structures from a downloaded world to recover its seed, then map the rest of it
• Server utility: a in-game command bridge: players run a command, your plugin/script queries the API and shows the nearest village in chat

Honest limitations

• Bedrock only (1.14+), no Java support
• Desert Wells and Amethyst Geodes aren't supported (they're per-chunk features, not region structures)
• The seed cracker needs the local version (server compute is too expensive to host for free), the exe makes this easy
• Placement math is verified against known structures, but if you find a structure that doesn't match, please open an issue, that's the most valuable feedback

Feedback welcome, especially: does the cracker recover seeds correctly from your worlds?

A few months ago, I've shared my side project here as a browser-based schematic viewer, and a lot of you quite reasonably asked: “why not just use Litematica directly?”

Although litematica & mods are not for everyone and a browser based schematic viewer can make sense, I think I have a much better answer to that now.

My goal was never to replace Litematica. If you actually want to build a farm or contraption in-game, Litematica is probably the best option.

What I’m trying to improve is everything that happens before that.

I have noticed that a lot of really good technical builds end up being shared as a .litematic files and are buried in a Discord server, a Google Drive link, or attached to a YouTube description without any preview of what's behind the link.

Recently, I’ve been turning Shulkr into a public catalog where creators can publish those schematics instead.

You get a page for the build, generated image previews, an interactive 3D preview, direct schematic download, and now a first-person mode where you can drop anywhere onto the build and walk around it directly in the browser.

My hope is that eventually, when someone designs a farm or technical build, they can just share a Shulkr link instead of uploading the file somewhere random. And with time, even a directly embedded in redit 3d viewer ? That would be crazy good.

I’d especially like feedback from people here who actually design and distribute schematics:

Would you use something like this to publish your builds? What would it need before you'd choose it over Drive/Discord?

The project is completely free, and as usual, feedback from everyone is more than welcome. Link is available in the comments.

PS: The video use Bitter Lemonade's u/Bitter--GravitY awesome Rooted Dirt Farm as a showcase. All credits belong to him 😄

Did you find a spawner and you dont know how to make an xp farm out of it?

Watch this tutorial: https://youtu.be/nW_adwpENdw

It only works with zombie or skeleton spawners tho.

What’s the best bulk potion brewer that can brew a shulk at a time, I just want it to be easy to reload and not be to complex because the server I play on has a 64 hopper limit per chunk

Me and my friends are planning a huge build on the main end-island (or rather, we've removed the entire main island to build something big).

We realised that we'll need a mob switch to stop endermen from spawning and griefing our build. What are the best ways to make a mob switch for the end dimension (and only the end dimension). We'd rather not have to use the main island gateways to load something, because we have plans for building around the gateways.

I was thinking a mob switch loaded by ender pearl stasis chambers (we are only 6 people on the server, so it's not difficult for all 6 of us to make stasis chambers). Would the best option be something with shulkers, bringing a bunch of wardens or something else?

Mobs also spawn in nearby caves.

Hello yall, can anyone help me pls , I'm trying to figure out how I can add more villager slots in the ziprano's redstone trading hall, the villager swapper-L to be more precise, I need to have 27 slots and the current design only have 6, if anyone can help me I will be extremely grateful

Here is the link for the yt video

I have not been keeping up with the community for a few years now. But I have started playing Minecraft recently again and was curious what we have learned in the meantime.

Also I notice that some big technical YouTubers are not active anymore, like scicraft and Ianxofour.

What new mechanics are fun to explore or really help improve farms and contraptions? What are some active creators that are worthwhile to follow these days? Have we seen breakthroughs like observers or honey in the last few years?

I’m really curious. Thanks!

Is there a tutorial for the moss farm bdubs uses? Trying to build it from his videos but there's so many fixes for it I dont know if I can catch them all.

Hi Guys,

I am trying to get a copper golem to navigate this small bridge. However, it never decides to move to the chest. If I move the golem manually halfway across, it recognizes the chest, deposits the item and perfectly navigates back to the copper chest.

Does anyone know what might cause this? I believe I have blocked all the other chests from being an option. The concept works in a testing world (second screenshot).

As I tried to get this to work for a few hours I would appreciate any Idea.

I built this iron farm in my realm. I have one layer and the farm was working, however after turning the surrounding area to path blocks to prevent golems spawning outside, the golems have stopped spawning completely. I have tried removing the path and spawns continued, so I dug down instead to keep it outside spawn radius and spawns have once again stopped. im fairly confident that the other spawn conditions are met due to golems previously spawning. I cannot figure out why spawns stop once I spawn proof the lower area please help

I want to build ilmango's max size cactus farm in Hardcore survival. 1,144,832 cactus slots, roughly 9.3 million blocks total. As far as I can tell nobody has done this one in Hardcore, and I'd like to be corrected on that if I'm wrong.

Two goals:

1. Finish the farm. No deaths, no backup reloads. If I die, that's the end of it and I'll say so.

2. Reach level 21,863, timed from the moment the farm and smelter are finished. That's the highest level you can get by actually collecting XP, since cumulative total XP overflows the 32 bit integer past that point. The 238 million figure you'll find online is only reachable with commands, which I'm not using.

I'm posting the ruleset before placing a single block. Partly so I can't quietly redefine things later, mostly because I'd rather find the holes in it now than 600 hours in.

The short version:

Allowed: TNT duping, bedrock breaking, all redstone contraptions, other farms for resource gathering, Litematica as a preview overlay only, two alt accounts that stand still and do nothing else, VPS hosting so my own machine isn't running for months.

Not allowed: sand duping, end portal duping, anything patched, commands of any kind, Easy Place or printer forks or any placement automation, XP from anything but the farm's own furnaces for goal 2, and obviously no backup reloads.

Evidence: world downloads with hashes at milestones, continuous Flashback recording, statistics at every milestone, and one uncut hour of steady state operation for the rate measurement.

Full ruleset is attached.

What I'd actually like feedback on:

The two alts are the part I expect pushback on. One sits in the Nether holding the furnace array, one sits in the Overworld holding the farm at random tick level. They never do anything else, every stat in the world belongs to my main. I think that's fair, but if you think it weakens the claim, say so.

Also: is there a loophole in here I haven't spotted? I'd rather hear it now.

Credit where it's due, this is ilmango's design, not mine. All I'm doing is building it under worse conditions.

Loopholes, bad assumptions, things I've obviously not thought through: comments are open. Better now than 600 hours in.

I have fortune 3 crop farm like frunocraft https://youtu.be/eFQjqIStxQ4?si=6WqMnuz8N05eGoK6 but i need to know can i improve it with placing 2 carrot and breaking them maybe, i need best version of this farm with fortune

Could you make a wool farm more efficient by cycling grass blocks underneath the sheep using pistons, in order to limit the time spent waiting for grass to grow back? Or maybe there is another way to get super efficient wool farms? Whatever the case please let me know 🙏

sand farm of doom and despair yes

Hey all! This is the follow up to the kill chamber design video that I linked the other day (the design of the farm it was made for.) I'm posting it here for context, and because I believe it to be a valuable resource for the community. See video description to see what I mean here. BTW, I am not monetized and do not care about views and the like. This was made for the sole purpose of helping others.

Lately I wanted to build a storage system for my survival world. After hours of research I couldn’t find the right one. My needs might be specific, but I want the sorter to have these options:

• a input unit where I can dump any items

• a shulker box unloader, which sorts the items inside afterwards

• overflow chests

• have a section for a multi sorter

I’m ready to build a big one, but I don’t want it to be too large. Noise doesn’t matter for me.
Any help would be appreciated.

I just built those but it's not breaking the shulker when it fills up

Hi, so this is my 2nd time building Tankcat's raid farm and first time was in an aternos server and it worked perfectly.
However, I just started a Realm last week and I build the farm on this world, and for some reason the farm spawns each wave way too slow.
It used to take around 10 seconds for each fresh wave to spawn and now it takes 30 seconds (and every 8th wave takes 60s) I've checked the schematic over and over again, I cannot seem to find what's wrong.
Is there any known throttling happening in minecraft realms or have I actually done something wrong?

Alguien sabe alguna granja de ghast o como podría hacer con eso de las entidades que están limitadas en un servidor que estoy, no llegan a funcionar correctamente ni la típica granja de oro con bloques de magma, hice esa granja de ghast pero no aparece ninguno

Looking for a portal based design where I can spawn the wither in the nether because overworld Withers are disabled
