Hello Vercel Team!

I'm developing HandyHub 2.0, an ERP SaaS platform intended for small and medium-sized businesses in the future.

I currently use Vercel Hobby for an older prototype, and I'm starting a new project from scratch with a stronger focus on security.

Before deploying it, I would like to clarify whether my situation qualifies for the free Hobby plan.

My situation:

• I'm developing the application personally.
• Development is expected to take approximately 5–8 months.
• The application will be used exclusively by me for development and testing.
• There will be no real customers, companies, subscribers, or paying users.
• All testing will use fictional data.
• The application will not generate revenue during development.
• Deployments will be private and protected using Vercel Authentication.
• The project will not offer commercial services during this period.
• I intend to upgrade to Vercel Pro before launching commercially.

My questions:

1. Can I use the Hobby plan for this private, non-revenue-generating SaaS prototype, even though I intend to commercialize it in the future?
2. Can I continue using Hobby throughout development, provided there are no real users or commercial activities?
3. At what point would upgrading to Pro become mandatory?
4. Could a Vercel team member confirm whether this use case complies with the Hobby plan's terms?

I want to respect Vercel's policies while avoiding unnecessary hosting expenses during the development phase.

Thank you for your help!
