Chunkbase alternatives: Minecraft seed maps compared
Chunkbase is still the most complete Minecraft seed map: Java 1.7 to 26.3 with Large Biomes, Bedrock 1.14 to 26.62, and the most structure types. Each alternative below does one thing differently: a larger accuracy test, a phone-first design, seed search on the desktop, or a map tested against the official server on every structure type. This page says what each tool does best and where Seedari, this site, falls short.

How to choose
- Match your edition and version first. Structures move between versions, and Java and Bedrock place them differently. For an upgraded world, pick the version its chunks were generated in.
- Check that the structure you need is covered: not every map shows strongholds, fortresses or end cities, and Bedrock coverage varies a lot.
- Look for measured accuracy, not the word "accurate": a page with numbers per structure, the versions tested and how many seeds.
- Want a seed that has something specific? You need a seed search (Cubiomes Viewer). Already have a seed? Any seed map will do.
- On a phone, try the map you pick: drag, pinch to zoom, and tap a marker.
Where Seedari is behind
- Bedrock is in beta: biomes, slime chunks and the world spawn only, for 26.60 – 26.63 and 1.21.120 – 1.21.132. Bedrock structures come once they match the official Bedrock server.
- About 1 in 20 Bedrock biome points still differ from the official server (95.1% match), all on biome borders.
- Our accuracy test uses 20 seeds per version. chunksout tests far more seeds; we check every structure type, they check more seeds.
- No seed search, no ores, no 3D view.
Where Seedari is different
- Tested against the official Minecraft Java server on 22 structure types, including the four chunksout does not show yet: strongholds, nether fortresses, bastions and end cities. Method, results and every mismatch are on the accuracy page.
- The homepage is the map: no form to fill in first, and it works the same on phones.
- Each finder page (village, stronghold, trial chambers and more) opens the map on that structure and lists the nearest five with coordinates.
- The link always keeps the seed, version, position and layers, so you can send exactly what you see.
Questions
Mostly, by its own account: its seed map page lists known limitations, saying many features are not 100% accurate, for example dungeons, the world spawn and amethyst geodes. It does not publish measured rates.
It depends on the structure. chunksout publishes the largest test, but does not show strongholds, nether fortresses, bastions or end cities yet. Seedari checks all 22 structure types against the official server (2,580 of 2,580 matched) on a smaller sample of 20 seeds. Whatever you use, confirm a far target with /locate before a long trip.
For Bedrock structures, Chunkbase still covers the most versions, and chunksout and MC Seed Maps show some checked structures. Seedari shows Bedrock biomes, slime chunks and the spawn in beta, without structures yet.
MC Seed View is designed for phones. Seedari opens straight on the map on a phone, with drag and pinch to zoom; Chunkbase lists touch gestures too. Try two or three with your own seed.
