three suggestions:

1. fyi, since your post links to https://lemmy.world/c/remy and https://lemmy.zip/c/remy icymi the preferred way to link to communities (so that everyone can access them via their own home instance) is like this: !remy@lemmy.zip. When someone types that in the lemmy web interface, it will auto-complete and expand it into link markup like [!remy@lemmy.zip](https://lemmy.zip/c/remy), but when that markup is rendered it will actually become a link to access the community via the reader’s home instance. For instance, for me that link will actually go to https://lemmy.ml/c/remy@lemmy.zip where i can interact with the community whereas https://lemmy.zip/c/remy will take me to the lemmy.zip website where i do not have an account. Here is a non-escaped example (my previous examples are all escaped with backtick characters to prevent them from rendering) which anyone should be able to click to load it through their own instance: !remy@lemmy.zip. Please ensure that your client can both generate and follow community links like this! (as well as user links to lemmy and other activitypub things; user links work the same except they’re prefixed with @ instead of !.)

2. you don’t need multiple communities for your app; users from .world can post on .zip and vice-versa (and it is easy for them to if you link to the community the way described above).

3. will you ever consider open sourcing it? :)
