The record

Purpose: Seeder is a browser app for finding, showing, sharing, and exploring Minecraft Java and Bedrock seeds.
Seed maps: Its interactive maps show biomes, spawn, strongholds, structures, and slime chunks across the Overworld, Nether, and End.
Seed finder: The finder searches for seeds matching multiple biomes and structures and offers presets for survival starts, speedruns, builders, and other searches.
Tools: Browser tools include a Nether portal calculator, stronghold finder, slime chunk and structure finders, circle and sphere generator, and seed poster maker.
Sharing and exports: Users can share seeds and searches by link, share seed images, and export finder results as CSV or JSON.
Supported editions: The site supports Java Edition from Beta 1.7 to 26.3 and Bedrock Edition from 1.18 through versions 26.50–26.52.
Browser processing: World generation and searches run in the user's browser using cubiomes compiled to WebAssembly, and the site says typed search input is not uploaded.
Privacy: Seeder says it has no accounts or server of its own; saved worlds and locations stay in the browser, while Google Analytics and AdSense are used.
Analytics details: The maker says Google Analytics 4 does not store IP addresses and data is kept for 14 months; typed coordinates, world names, notes, and other written text are not collected.
Saved-world limits: The browser can store up to 50 worlds and 200 locations per world, and the maker says users must export backups because browser data may be wiped.
Performance: Seed searches are CPU intensive and may slow the user's device; the maker says biome searches can be especially slow from Minecraft 1.18 onward.
Bedrock limitations: The maker cautions that Bedrock structure predictions can be inaccurate, the spawn is estimated, and the End's outer islands may differ.
Support: Users can report bugs and ideas on GitHub or contact the maker by email or Twitter; the site also accepts donations.
Funding: Seeder is free and funded by ads and donations.
