How It Works
Two-layer architecture:
- Card data layer — Full card database from HearthstoneJSON, stored in a local SQLite database with FTS5 full-text search. Cards are fetched on first run and updated when newer game builds are available.
- Strategy layer — Built-in strategy knowledge covering archetypes, class identities, matchup theory, and core game concepts. Enables the server to provide coaching and analysis, not just raw card data.
Data Source
Card data provided by HearthstoneJSON by HearthSim. Auto-extracted from game files. Unrestricted use.
