A website mainly presents information; a web application lets users log in and get work done — order, pay, track, collaborate or manage data.

Can you take over an existing SaaS codebase?

Where will my application be hosted?

On AWS, Azure, Google Cloud or DigitalOcean, in the region closest to your users and compliant with your data-residency needs.
