SaaS (Software as a Service) app development refers to the creation of cloud-based software applications that are hosted and delivered over the internet. Unlike traditional software, which is installed on a user’s device, SaaS apps are accessible via a web browser, allowing users to access the application from any device with an internet connection. SaaS app development involves building scalable, multi-tenant platforms that can serve multiple users simultaneously while maintaining data security, performance, and ease of use. These apps are typically subscription-based, making them cost-effective for users and offering recurring revenue for businesses.
