Stardewpedia: The Stardew Valley Database
A Stardew Valley database covering every item, villager, crop and recipe in 1.6.15.
Villagers, gifts and the calendar
Pelican Town has 50 villagers, 34 of whom accept gifts and 12 of whom you can marry. Two gifts a week each, and the right one is worth eight times the wrong one, so the gift guide lists what all 34 of them love, like, dislike and hate in one place. Every villager also has their own page with their birthday, family, where they live and the full taste list.
Timing is most of it. The calendar puts all 34 birthdays and 12 festivals on one grid, because a loved gift on a birthday counts eight times over. The festivals pages say who turns up to each one and what they say, and the heart events page covers all 107 friendship cutscenes, what triggers them and when, behind a spoiler reveal so you can look up one without spoiling the rest.
Beyond gifts there is the movie theater, where an invitation to a film someone loves is worth as much as a loved gift and does not use up your two for the week, and pets, which need petting daily and count toward Perfection.

Your farm, planned properly
The farm planner runs on the real game maps for all 8 farm types in every season, with the genuine tillable and buildable tiles underneath, so a layout that works here works in game. Drag to fill, and sprinkler and scarecrow coverage is drawn as you place them.
What goes on it: 50 crops with growth times, regrowth and which seed becomes what; 14 farm animals with prices, produce and how long each takes to mature; and 25 buildings with the cost, materials and footprint of each. House upgrades covers the three farmhouse tiers, what each one unlocks and Robin's full renovation menu.
Turning a crop into money is usually a machine job: all 39 of them, what goes in, what comes out and what it sells for. The 54 location maps cover everywhere else, at full detail and in every season that changes.

Every item in the game
All 2207 items, each with its sprite, sell price, category and what it is used for, cross-linked both ways: from an item to the recipes that need it, and from a recipe back to its ingredients. That covers 81 cooking recipes and 150 crafting recipes, with how each one is unlocked.
74 fish get their own treatment, since catching one depends on season, weather, time of day and where you cast. Individual fish pages carry those conditions directly.
For everything cosmetic there is 322 tailoring recipes, 122 hats, 339 pieces of clothing, 235 wallpapers and floors and 74 hairstyles.

Bundles, the museum and Perfection
The Community Center is 31 bundles, listed with everything each one wants and a checklist you can work through. The museum covers every artifact and mineral Gunther will take, plus what each donation milestone gives back.
39 achievements and every permanent power sit alongside 99 quests and special orders, and 51 monsters with their health, damage, drop tables and the Adventurer's Guild kill goals.
The odd corners are here too: all 38 secret notes, each hidden behind its own reveal, the 9 garbage cans worth checking daily, and the 72 fish you can put in a tank.

Games
Two daily quizzes built on the same checked data as the rest of the site, so a right answer really is right. Who's That Villager? zooms in on one of the 47 portraits until only hair and eyes are left. Who Loves This Gift? shows an item and asks which villager loves it, drawn only from gifts exactly one person loves so there is always a single right answer. See both.
