Why this site exists
Stardew Valley contains many RNG-based systems that become easier to plan when the save state is readable. Geode results, mine events, cart stock, train schedules, weather, Winter Star assignments, and enchantment order can all matter when a player is trying to complete a museum collection, route a Skull Cavern day, find a rare cart item, or avoid wasting resources.
Stardew Predictor puts those checks into a tool-first website. The homepage runs the main predictor, while focused pages help players start directly with common tasks such as geode prediction, seed analysis, Skull Cavern planning, and Traveling Cart tracking.
How the tool works
The browser tool reads a Stardew Valley save file or Game ID parameters, prepares the relevant save state, then simulates supported RNG systems. A real save file is usually the best input because it includes counters, player IDs, game version, unlock flags, mine state, donation state, and other details that a seed alone cannot supply.
The tool is based on a JavaScript predictor implementation released under the MIT License by MouseyPounds. This site adapts that predictor into a modern tool-first SEO structure while preserving the important browser-based prediction workflow.
