What Seeder is
Seeder is a free browser app for finding, viewing, sharing, and exploring Minecraft Java and Bedrock seeds. Its interactive maps show biomes, spawn, strongholds, structures, and slime chunks across the Overworld, Nether, and End. The seed finder searches for combinations of biomes and structures, with presets for survival starts, speedruns, builders, and other searches. Other browser tools include a Nether portal calculator, stronghold finder, slime chunk and structure finders, a circle and sphere generator, and a seed poster maker. Users can share seeds and searches by link, share seed images, and export finder results as CSV or JSON. Java Edition support runs from Beta 1.7 to 26.3; Bedrock support runs from 1.18 through versions 26.50–26.52. World generation and searches run in the browser using cubiomes compiled to WebAssembly, and the site says typed search input is not uploaded. Seeder says it has no accounts or server of its own, though it uses Google Analytics and AdSense. Browser storage holds up to 50 worlds and 200 locations per world; users need to export backups because browser data may be wiped. The free service is supported by ads and donations.
