At the moment the guides available at https://ronin.co/docs could be used for getting started! We're working on landing a starter boilerplate in the coming weeks (early 2024).
Only the "Serverless Function Region" feature, meaning being able to select which specific region a Serverless Function runs in, is only available for Pro Teams.
It seems as if this wasn't clear from the UI. Would you agree? It sounds like you've assumed that it's the entire Serverless Function feature that would not be available.
Whenever the Next.js + Vercel combo gains a new feature, Vercel ensures that it's available in standalone Next.js too – even when deployed to other providers.
That's true for all the features mentioned in the Next.js 10 blog post: Image optimization, Internationalization, but also Analytics.
Since you mentioned the latter: Did you notice that we wrote a detailed documentation page about how to report those metrics to any service of your choice?
Sure, there's obviously a whole UI piece to this as well – but since you interact with Next.js programmatically and there's a quite sophisticated data storage that needs to back all of this as well, Vercel optionally provides you with a pre-built solution.
But again, to be clear: If you want to use Analytics + Next.js elsewhere, Next.js supports reporting them natively – even if not hosted on Vercel.
