Is Chaldea Cross-Platform and How Do I Start Using It?

Yes. Chaldea (chaldea.center) is described as a cross-platform tool for Fate/Grand Order, so you can use it across different devices rather than being tied to one platform. To start, open the site in a browser with JavaScript enabled, wait for it to load, then use the linked document site for setup and usage instructions.

What Chaldea Is

Chaldea is a cross-platform tool for Fate/Grand Order made up of two parts:

• Chaldeas — a planner for materials, servants, events, and similar planning tasks.
• Laplace — a battle simulator for building teams and working on 3T farming.

So if your goal is planning resources or testing team compositions, both functions live inside the same tool.

Requirements Before You Start

The main practical requirement shown on the site is:

• JavaScript must be enabled. The page states you need to enable JavaScript to run the app. If scripts are blocked, the tool will not load.

Because it is described as cross-platform, you can access it from a standard browser on your device. The site does not list specific operating systems, browsers, or installable apps in the available information, so treat "cross-platform" as browser-based access rather than a confirmed native app for every platform.

How to Start Using It

1. Open chaldea.center in your browser.
2. Make sure JavaScript is enabled for the site.
3. Wait for the app to load — it shows a "Starting..." state during startup.
4. Once loaded, follow the link to the Document Site for detailed instructions.

The document site is the intended place to learn the actual workflows, so use it rather than guessing at menus.

Common Stops

• Blank or stuck page: almost always JavaScript being disabled or blocked. Enable it and reload.
• Not sure what to do after loading: go to the document site linked from the app; that is where usage guidance lives.
• Assuming a native app: the available information only confirms a cross-platform tool, not downloadable clients for each platform.
