I’ve seen this asked a few times over the years here, but haven’t been able to find a follow up. The use case I’m investigating is having a large number of areas that represent a school, which house discussions for each school. There is no requirement to restrict access permission to these areas, other than perhaps an option to “join”. Also having sub-categories within each of these areas would be required. I’ve noted that a large number of categories / sub-categories in discourse is not recommended, while a large number of groups might be an option? Although it seems groups would need to be linked to categories anyway? Running multisite instances seems like overkill given the overall traffic would not exceed a “normal sized forum”. In fact I suspect a large number of these “areas” might never see any traffic ever, yet they need to exist so they can be found if required. > [@Most effective way of creating large amount of sub-forums](https://meta.discourse.org/t/most-effective-way-of-creating-large-amount-of-sub-forums/83583): > > Hi, We’re looking at implementing discourse into an existing application which has a large userbase broken down into schools at the nationwide level. In an ideal world, each school with have its own private “sub-forum” of which only users from that school can post, which each sub-forum having approx 3 categories (always the same). If this setup something thats possible in discourse and if so whats the best way of implementing this assuming there may be thousands of schools/sub-forums?

What’s the maximum number of categories we can have? Is it 1000? 10,000? 100,000? I plan to heavily use the API and create a custom frontend for both web and mobile. Part of this is programmatically creating a new Category whenever a user wants to. So it’s more of a backend systems question than the UI. For example, will the /categories.json endpoint scale?
