What is SaaS Application Development?

SaaS is a cloud-based software that provides ready-made software to users through a web browser or mobile application without the need to purchase or install it on computers. Instead, they subscribe to the SaaS app on a pay-as-you-go basis. The best part? Users don’t have to worry about maintenance or updates, as everything is handled automatically by the software provider.

The SaaS application development model is a modern upgrade to the traditional client-server software delivery system. In the client-server, software runs on the client side while in the SaaS model, it resides on the server side and is accessed remotely by users.

SaaS development eliminates the need for heavy infrastructure investments, making it more affordable and accessible to companies of all sizes. Popular examples of SaaS apps include Salesforce, Dropbox, and Google Workforce.

Why SaaS Development Matters in 2025?
