What is SaaS?
SaaS (Software as a Service) is a software distribution model in which a cloud provider hosts applications and makes them available to end users over the internet.
In 2026, building a SaaS is easier than ever, but growing one is harder. Successful "Indie Hackers" and startups don't build everything from scratch. They use a specialized stack of tools to move fast.
