Choosing the right tech stack is one of the most important decisions when building a SaaS product. The wrong technology can limit growth, increase maintenance costs, and make hiring developers harder.
The good news: there is no universal perfect stack. There is the right stack for your product, team, and growth stage.
Start with the product, not the hype
Before choosing React, Next.js, or any framework, define product requirements: user types, expected volume, required integrations, real-time needs, and monetization model.
A validation MVP has different needs than an enterprise platform with thousands of active users.
Recommended stack for modern SaaS
For most B2B and B2C SaaS products, a combination of Next.js + TypeScript + PostgreSQL + Stripe offers an excellent balance of development speed, performance, and scalability.
For real-time features, consider Supabase or Firebase. For AI workloads, integrate OpenAI or Anthropic via API with a dedicated backend layer.
Avoid over-engineering early
Microservices, Kubernetes, and distributed architectures are powerful but rarely needed in an MVP. Start with a well-structured monolith and refactor when you have real usage data.
The rule of thumb: optimize for time-to-market in the first 12 months, then optimize for scale.
Conclusion
The best stack is the one your team knows and that lets you deliver value quickly to customers. If you need help defining your SaaS architecture, Northbridge Labs can audit your project and recommend the ideal approach.
