openCook is an open-source, offline-first recipe app. Collect, plan and cook your recipes — without an account, ads or tracking. Recipe management, meal planning and the shopping list work fully offline on your device. An optional self-hosted server (which you run yourself, on your own hardware) adds AI photo scanning and family sync over your home network — there is no cloud and no registration. Features: * Works fully offline — your recipes never leave your device * No account, no ads, no tracking * Turn cookbook photos into structured recipes (optional self-hosted AI) * Rolling meal planner that tells you why a dish was suggested * Shared shopping list * Barcode scanning via Open Food Facts * Import recipes from the web, or browse recipe sites right inside the app * Family sync through your own home server, or phone-to-phone over Wi-Fi * Available in English, German and French openCook is free software licensed under the GPLv3.
