Hey! Welcome to my mod, Crackers. A completely client-sided mod to extract the seed from Singleplayer and Multiplayer worlds made by reverse-engineering Minecraft's terrain and structure generation.
In Singleplayer, just join the world and the mod will read the seed from the host, regardless of permissions. However, if you join a multiplayer server the process takes a little longer but still very straightforward.
To get the seed of a multiplayer server you must simply walk around the world and explore (like you would normally do in Minecraft). Crackers will silently gather data ("bits") of structures and features in your render distance. Once you have enough of them, Crackers will compare the data against a hashed seed and give the seed, usually under ~30s.
You can open the UI and track progress (among other things) with /cracker.
Once the seed has been found you are free to copy it to your clipboard and boom! You have the entire world in your hands...
Tip: A way to expedite your cracking process is to visit the End and wander around the End Pillars. The easiest way to collect the most bits is sailing the 7 seas and finding shipwrecks.
