What SeedFinder is
SeedFinder helps Minecraft players locate structures from a world seed and player position, and its SeedCracker tool searches for Bedrock seeds matching structures near coordinates you provide. The supported structure list includes villages, temples, ocean structures, ancient cities, mansions, portals, buried treasure, mineshafts, trail ruins and trial chambers. SeedFinder’s browser console runs scans locally through WebAssembly without an account, key or download. Its REST API accepts GET or POST requests and returns JSON; examples are provided for Python, Lua and Node.js. The hosted API allows 60 requests per IP per minute, with scans limited to a 1,000-chunk radius and 200 results. An in-game overlay integration is available through Flarial Client. SeedCracker needs coordinates for at least four structures. It runs in the browser, while its hosted HTTP API is offline; the documented HTTP API runs on a local server. The site says browser scans need no connection to a Minecraft world or third-party seed map. The listed plan is free.
Good
- Browser scans run without an account, key or download.
- Supports many listed structure types.
- REST API returns JSON results.
- Flarial Client integration offers an in-game overlay.
Watch out
- Hosted API is limited to 60 requests per IP per minute.
- Scans cap at 1,000 chunks and 200 results.
- SeedCracker needs four structures with coordinates.
- SeedCracker's hosted HTTP API is offline.
Who it suits
SeedFinder suits Minecraft players looking for structures from a seed and position. SeedCracker is for players trying to find a Bedrock seed from a chosen structure layout, provided they have coordinates for at least four structures.
Verdict
SeedFinder combines browser-based structure scans with a JSON API and an optional Flarial Client overlay. SeedCracker can search for a Bedrock seed from structure coordinates, but its hosted HTTP API is unavailable.

The full review of SeedFinder
SeedFinder is a free set of Minecraft tools for finding structures or narrowing down a Bedrock seed from coordinates. It suits players who want browser-based scans, API access or a Flarial Client overlay. Its structure search is flexible, but SeedCracker’s hosted API is offline and the service does not provide a map preview.
Overview
SeedFinder locates nearby structures in Bedrock and Java worlds from a seed and player position, while SeedCracker works in reverse: provide coordinates for selected structures and it searches for a matching Bedrock seed. That split makes it useful both for exploring a known world and investigating an unknown one. SeedCracker needs coordinates for at least four structures, so it is not a shortcut from a single landmark to a seed.
Key features
- Structure scans: Search for villages, temples, ocean structures, ancient cities, mansions, portals, buried treasure, mineshafts, trail ruins and trial chambers. Terrain analysis is supported, but there is no map preview; readers who want a browsable visual map should look elsewhere.
- Browser console: Scans run locally in the browser through WebAssembly, with no account, key or download required. The site says the console does not need a connection to the Minecraft world or a third-party seed map, a useful boundary for players wary of sharing world data.
- REST API: GET and POST requests return JSON, with examples for Python, Lua and Node.js. The hosted API allows 60 requests per IP per minute, with scans capped at a radius of 1,000 chunks and 200 results. Those limits suit modest integrations, not high-volume scanning.
- Flarial Client overlay: The SeedFinder module can display nearby structures in-game, avoiding the need to switch between a game and browser during play.
- SeedCracker: The browser version runs through WebAssembly. Its hosted HTTP API is offline; the documented HTTP API runs on a local server, so developers should not rely on a hosted endpoint for this tool.
Pricing
SeedFinder’s Free plan costs nothing and includes the hosted API and browser tools. There is no free trial because the core tools are already free. The main trade-off is capacity: the hosted API is limited to 60 requests per IP per minute, 1,000 chunks of scan radius and 200 results. The browser console avoids the need for an account or key, but SeedCracker’s hosted HTTP API remains offline.
Platforms
SeedFinder is offered on web, Linux and Windows, with API and self-hosted options. Edition support is Bedrock, while the stated structure-finding purpose also covers Java. The browser console runs scans through WebAssembly; the local-server option applies to SeedCracker’s documented HTTP API.
Who it's for
Choose SeedFinder if you play Minecraft and want to locate supported structures from a known world seed, or if you have coordinates for at least four Bedrock structures and want to search for a matching seed. It also fits developers who can work within the hosted API’s quotas or run SeedCracker’s HTTP API locally. It is a weaker fit for anyone who needs a visual map preview, wants to infer a seed from fewer than four structures, or depends on a hosted SeedCracker endpoint.
Pros and cons
- Pro: Browser scans need no account, API key or download, reducing setup before a search.
- Pro: JSON output and code examples for Python, Lua and Node.js give developers a direct route to integrating structure results.
- Pro: The optional Flarial Client overlay puts nearby structures in-game.
- Con: The hosted API’s per-IP request, radius and result caps constrain larger or repeated scans.
- Con: SeedCracker requires four structure coordinates and has no hosted HTTP API, limiting quick searches and hosted integrations.
- Con: No map preview means results lack a visual browsing layer.

Verdict
SeedFinder is a strong fit for players who want free structure scans without installing software, and for developers who can use its JSON API within the quotas. Its combination of local browser scanning and an in-game overlay is practical, while SeedCracker adds a focused Bedrock reverse-search option. Look elsewhere if you need a map preview, a hosted SeedCracker API or seed searches from fewer than four structure coordinates.

Limits worth knowing
The free hosted API is limited to 60 requests per IP per minute, with scans capped at a 1,000-chunk radius and 200 results. SeedCracker’s hosted HTTP API is offline, and its seed search requires at least four structures with coordinates.
