SaaS is a subscription-based service that allows users to access software over the Internet. On the other hand, web applications are standalone programs that run in a web browser. Companies design them to offer business users and consumers a specific feature or function. While there are some clear distinctions between SaaS and web applications, it’s important to note that many SaaS applications also have web versions. SaaS web development allows users to access the same features and functionality, whether using a web browser, desktop, or mobile device.
