How to run tests against multiple apps as one test suite

[Murderlon]

I'm investigating using cypress for transloadit/uppy. As we build libraries and not a single full-stack app, our e2e tests are against test apps which compose our libraries in a certain way we want to test them. Cypress seems to focus on testing against a single app, running on one (localhost) port. But what if I have lots of folders, each being their own small Vite app for instance (or just static files), and I want to run those as one test suite? Is that possible somehow?
