Every home cook keeps a graveyard of recipes scattered across bookmarks, screenshots, chat threads, and one stained index card, and CookTrace gathers the whole mess into one self-hosted library that knows what is in your pantry. Import recipes from URLs, files, or photos, or bring entire Mealie, Paprika, and Tandoor archives in bulk, then cook with live scaling that does fraction-aware ingredient math, per-step photos, and an inline unit converter. A pantry-match pill on every recipe card tells you at a glance what you can actually cook tonight, while barcode scanning and expiration digests keep stock honest. The cook diary and meal planner move from list to month calendar with drag-to-re-plan, and the shopping list generates itself from planned recipes, skipping items you already own and grouping the rest by aisle. Households organize into cookbooks and shared Kitchens with public links, and an optional conversational assistant can log a cook, plan a meal, or import a recipe for you. An opt-in MCP server even exposes your recipes and lists to external AI agents under token-scoped tool tiers. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
