What it is

SeedFinder locates Minecraft Bedrock and Java structures from a seed and player coordinates. Its browser tools run through WebAssembly without an account, key, or download. A REST API returns JSON, while a local server removes the hosted request limit. SeedCracker can work backward from structure observations to find matching Bedrock seeds.

Good, and not so good

  • Free browser console and API
  • Supports Minecraft Bedrock and Java
  • No account, download, or API key for hosted tools
  • Local server avoids the hosted per-IP limit
  • Open-source Zlib-style license
  • Hosted API allows 60 requests per IP per minute
  • Scans cap radius at 1,000 chunks and results at 200
  • No hosted SeedCracker HTTP route
  • Several structures are unsupported
  • No map preview; coordinates are predictions

Who it suits

Players locating supported structures from a known seed Developers needing a small JSON scan API Bedrock players searching from structure observations

SeedFinder is a sensible free option for locating supported Minecraft structures from known seeds, especially when you want browser-only use or a small JSON API. Self-hosting gives more control and removes the hosted per-IP limit. Reverse seed searches are more demanding: hosted HTTP cracking is unavailable, and Bedrock cracking needs several observed structures. Check the unsupported structure list and version-accuracy warning before relying on results. Players who need a visual map, broader Nether and End coverage, or a hosted cracking endpoint should choose another tool.

Questions

Does SeedFinder support Bedrock and Java?
Yes. The hosted tools and API support Minecraft Bedrock and Java editions.
Do I need an account or API key?
No. The browser tools need no login, account, sign-up, download, or key. The public REST API also works without an API key.
What does SeedFinder return?
Give it a world seed and coordinates, and it returns nearby structures with coordinates and distances. Requests can include several structure types.
What is the hosted API limit?
The hosted API allows 60 requests per IP per minute. Scans cap the radius at 1,000 chunks and results at 200.
How does SeedCracker work?
SeedCracker searches for seeds matching structures and coordinates. Automatic Bedrock cracking needs at least four structure observations; its hosted HTTP route is offline.
Can I run SeedFinder locally?
Yes. A local server listens on 127.0.0.1:7890 by default and does not impose the hosted per-IP limit. A packaged Windows executable includes the server.
Which structures are unsupported?
The public list does not expose Bastion Remnants, Nether Fortresses, or End Cities. Documentation also marks Desert Wells and Amethyst Geodes unsupported.
Are the coordinates exact?
They are predictions. The project warns that results can differ when Minecraft world-generation versions change.
