Minecraft Stronghold Finder FAQ
How does this Minecraft Stronghold Finder work?
It generates the 128 Stronghold starting positions for your Java 26.2 Seed inside a browser Worker and returns the position nearest to your X/Z origin.
Does the result point to the End Portal room?
No. It is the starting-chunk X/Z used by Minecraft's locate system. Explore the Stronghold to find the portal room and its Y level.
Does MapMC receive my Seed or coordinates?
No. Calculation happens in your browser, and shared state remains after the URL # symbol rather than being sent as a normal page request.
Does this Stronghold Finder support Bedrock Edition?
No. Results are verified for unmodified Minecraft Java 26.2 only, so they must not be used as Bedrock coordinates.
