Hey, does anyone know and/or use an OSS grocery list?

That’s something I wasn’t able to digitalize, but I want to…

I’m looking for a grocery list server (hostable via Docker) that I can access from my smartphone or Desktop, but haven’t found a good solution yet.

I know, there are Markdown note taking apps like Joplin and I’m using them as a private “knowledge base”, but I wasn’t convinced of them as grocery lists. I imagine, there could be some optimizations like templates for stuff you buy every time or auto-completions (e.g. if you type “papr” and there was “paprica” in your list history, it could auto-complete or at least suggest the word…).

How are you doing it? Already digitalized or still on paper? If digitalized, via some subscription service behind it or self-hosted?
