What MC Seed Gen is
MC Seed Gen is a free web tool for generating Minecraft world seeds and examining existing ones. It supports Java Edition and Bedrock Edition, showing spawn coordinates, the spawn biome, nearby structures, and surrounding biomes for a seed. Its search can look through random worlds for one or more target spawn biomes and save seeds that match. Presets check up to 500, 1,500, or 5,000 worlds and collect up to 3, 5, or 10 matches, respectively. A directory provides thousands of seeds across 45 biomes, and clicking a seed number copies it for pasting into Minecraft. Supported seed values are whole numbers from -9,223,372,036,854,775,808 through 9,223,372,036,854,775,807. Since Minecraft 1.18, Java and Bedrock produce identical terrain from the same seed, although structure placement can differ by edition. The plan is free at no cost, and there is no trial. The site says it is not affiliated with Mojang Studios or Microsoft.
