Pantrix

Pantrix is a self-hosted kitchen planner. Save recipes and the ingredients they use, keep track of what is in your refrigerator, freezer and pantry, and plan meals on a calendar. A recipe line can accept substitutes ("penne or elbow pasta"), and a planned meal can be a recipe, a single ingredient such as a packaged meal, or eating out. The shopping list writes itself: it always holds what your upcoming meals need plus anything below the minimum you set, less what you already have. Add your own items, check things off as you shop, and save one-off items as ingredients for next time. Add the stores you shop at and record which aisle each item is in at each one. Pick the store on a shopping list and it sorts into walking order. Each item can also carry the exact product you usually buy and a link to its page on the store's website. Store addresses can be looked up through OpenStreetMap.
