SaaS
SaaS (Software as a Service) is a software distribution model where applications are hosted in the cloud and accessed by customers via web browsers on a subscription basis. SaaS products serve multiple customers from a single codebase using multi-tenant architecture.
SaaS is the dominant model for modern software delivery. Instead of installing software on individual computers, users access the application through a web browser. The software provider hosts the application, manages updates, handles security, and ensures availability. Customers pay a monthly or annual subscription fee. SaaS products use multi-tenant architecture where a single instance of the application serves multiple customers while keeping their data separate. This model benefits both providers (predictable recurring revenue, single codebase to maintain) and customers (no installation, automatic updates, lower upfront cost).
The global SaaS market is highly valued. For businesses building SaaS products, the subscription model provides predictable recurring revenue that investors value highly. For businesses using SaaS products, the model offers lower upfront costs and reduced IT overhead. However, long-term SaaS licensing costs can exceed custom software development costs, particularly for products with per-user pricing.
SaaS products are built as web applications with multi-tenant database architecture (typically PostgreSQL with schema or row-level isolation), subscription billing (usually Stripe), authentication and user management (Clerk, Auth0), and cloud hosting. Modern SaaS products are built with Next.js, React, and TypeScript for the frontend, with Node.js or Python backends.
