If finally happened! Herobrine world seed has been discovered. The Minecraft seed was found by andrew_555 known as Kminster, who kicked off their search on 5th September, 2020. Kminster admitted it “probably about 50 hours in total for developing/writing the code”, but eventually stumbled upon the world on 16th January 2021.
Since the first Herobrine Creepypasta, many people have faked his Minecraft world multiple times. So they've used their seed cracking knowledge from Pack.png and the Minecraft panoramas to find the seed once and for all! – They've commented.
Please note that Herobrine is not real and has never been, this is just the seed used for the original creepypasta image, so if you're looking for the actual Herobrine NPC, sadly there is not one.
