How to Build a Scalable SaaS in 2023
When I launched my first SaaS product back in 2018, I made almost every architectural mistake possible. We chose the wrong database, overengineered our infrastructure, and underestimated the complexity of multi-tenancy. The result? Countless late nights debugging production issues and a codebase that became increasingly difficult to evolve.
Fast forward to today, and I've helped build and scale several successful SaaS platforms. The landscape has changed dramatically in just a few years—new tools, platforms, and patterns have emerged that make building scalable SaaS applications more accessible than ever.
In this post, I'll share the hard-won lessons and current best practices for building a SaaS that can scale from your first customer to your first thousand, without requiring a complete rewrite along the way.
