Should be easy to use, remember what I bought before and propose things that are probably running out (based on my personal buying frequency), and allow sharing the list between multiple people. Ideally also allow adding recipes for meals that I cook often.
I think the closest to you requirements will be Grocy. You can define list of products you use, current stock, rules to add product to the shopping list based on amount, what to do when you move product between storage locations (e.g. move from freezer to fridge), etc. There’s also a mobile app. Having said that I stopped using it after couple months. Few reasons: mobile app had no offline mode, mobile app was not compatible with the latest app server version, I had many issues setting up current stock (many times I had to manually adjust the amounts after using consume/purchase option). Overall I like the idea but it didn’t work for me.
I think out of the 3 kitchen and recipe managers I know, Grocy sounds most like it.
At that point, you might as well get Mealie.
- Recipe manager (with online recipe parsing so you don’t have to read everyone’s life story)
- Equipment and ingredient lists per recipe
- Meal planner so you can plan out a week of meals
- Shopping lists by adding item by item or actually linking recipes and automatically importing all of the items
- Different users and access control, OIDC, backups, and most modern features.
I am on the fence about Tandoor at the moment.
But there is this bunch. https://github.com/awesome-selfhosted/awesome-selfhosted?tab=readme-ov-file#recipe-management
Grocy seems to match what you’re looking for.
I use Grocy for the shopping list feature. It has a lot more functionality tho.
