MC Seed View is a free, fast, and interactive Minecraft seed map viewer powered by cubiomes WebAssembly. Explore biomes, locate structures, and plan your adventures — all in your browser. No download required, no account needed, and your seeds are never sent to any server.
Explore the full Overworld, Nether, and End with accurate biome rendering. Zoom from world overview to chunk-level detail.
Locate Villages, Strongholds, Mansions, Monuments, and 20+ structure types. Click any icon to get exact coordinates and /tp commands.
Supports Java Edition 1.0–1.21 and Bedrock Edition. Accurate biome generation across all major Minecraft versions.
Search for seeds that match specific criteria — find the perfect world with villages, strongholds, and monuments near spawn.
Each seed is automatically evaluated and graded (S/A/B/C/D/F) based on nearby structures, biome diversity, and spawn location quality.
Available in English, Japanese, Korean, Chinese (Simplified & Traditional), Thai, Vietnamese, Indonesian, and Hindi.
Save the current map view as a high-quality image. Share seeds with a link that includes coordinates and zoom level.
Mark structures as completed and track your exploration progress per seed. Export and import your data between devices.
MC Seed View compiles the cubiomes C library to WebAssembly using Emscripten. This means all biome and structure calculations run entirely in your browser — no server processing needed. The same algorithms used by Minecraft Java Edition are executed client-side for maximum accuracy and privacy.
| Component | Technology |
|---|---|
| Biome Engine | cubiomes (C) → WebAssembly via Emscripten |
| Map Rendering | HTML5 Canvas with custom tile system |
| Computation | Web Workers for non-blocking processing |
| Hosting | Cloudflare Pages + Workers (edge routing) |
| Database | Supabase (gallery & feedback) |
| Frontend | Vanilla JavaScript — no framework |
In addition to the main map viewer, MC Seed View offers 20 individual tool pages for quickly finding specific structures:

Open MC Seed View →MC Seed View is independently developed and maintained by Satoru, a software engineer with over a decade of programming experience across web, mobile, and systems engineering, and a long-time Minecraft household — the tool is shaped both by hands-on development and by daily feedback from a family member who has spent years playing both Java and Bedrock Edition. The project began in 2025 with a clear focus: build the fastest, most accessible, mobile-friendly Minecraft seed viewer the community has — and keep it free forever.
The tool is built around the open-source cubiomes C library — the same world-generation algorithm reference used by other trusted Minecraft seed tools — compiled to WebAssembly via Emscripten and wrapped in a deliberately lightweight vanilla-JavaScript front-end (no React, no framework bloat). The result loads in under one second on a typical modern phone, runs offline as a Progressive Web App after the first visit, and never sends your seed value to any server. Every biome and structure calculation happens locally inside your browser.
Most existing Minecraft seed map tools either require a backend (so your seeds get logged), lock you into a desktop browser, or fall behind when Mojang ships a major version update. MC Seed View was built to solve all three at once: zero backend, mobile-first interaction, and rapid updates when new Minecraft versions arrive. The current roadmap centers on Minecraft 1.21.x feature parity, expanded Bedrock Edition support, and ongoing performance tuning to keep map rendering smooth on lower-end devices.
This project is run independently. There are no investors, no acquisition plans, no premium tier. Display advertising (via Google AdSense) covers the modest hosting and domain costs needed to keep the service free for every player who visits. We do not collect personal data, do not require accounts, and do not share information with third parties beyond the standard analytics and ad delivery cookies disclosed in our Privacy Policy. If MC Seed View ever has to change this model, it will be announced clearly on this page first.
