Frequently asked questions

Q.Do you build the SaaS from scratch or use a boilerplate?

Both. We start from a proven foundation of authentication, billing and multi-tenancy to save time, and build all the business logic specific to your idea on top of it. We do not reinvent the wheel, but we do not hand you a template either.

Q.Can I scale to thousands of users?

Yes. The architecture is designed to scale horizontally from the start. Going from 10 to 10,000 users is a matter of infrastructure, not of rewriting the product.

Q.Does it include an admin panel?

Yes. Your operations team gets a panel to see users, invoices and metrics, and to run the platform without touching code or databases.

Q.Who owns the code?

You do. The code is yours, it lives in your repository, and you can take it to another team whenever you want. There is no lock-in with Prometeo.
