TECH STRATEGY

Rules for Selecting SaaS Tech

Choose Boring Technology

Use tech that is at least 3 years old. You want stack overflow answers and documentation, not bleeding-edge bugs.

Optimize for the Team

Do not pick Python if your team knows JS. Even if Python is 'better' for the task, learning a new language destroys velocity.

PostgreSQL by Default

Unless you have a very specific NoSQL need (95% of startups don't), Postgres is the undisputed king of relational data.

Never Build Auth

Do not build your own auth/login system. Use Clerk, Supabase, Auth0, or NextAuth. Security is not where you should innovate.

Avoid Premature Microservices

Start with a monolith. Next.js, Rails, or Laravel. Do not break into microservices until a team size of 20+ forces you to.

PaaS Over IaaS

Use Vercel, Render, or Heroku to start. Do not build Kubernetes clusters on AWS on day one. Pay for convenience over server ops.

How to Choose the Best Tech Stack for Your SaaS

Your technology stack is the foundation of your software company. While a great tech stack won't guarantee product-market fit, a terrible one can definitely kill your startup through slow shipping velocity, accumulating technical debt, and catastrophic security vulnerabilities. When choosing a stack, founders must balance three competing priorities: developer familiarity, scalability requirements, and operational costs.

The Golden Rule: Boring is Better

The biggest mistake technical founders make is "Resume Driven Development" — picking the newest, shiniest framework because it looks fun to learn. Startups are hard enough; you don't want to fight framework bugs while trying to find product market fit. The standard advice is to choose "Boring Technology". Technologies like PostgreSQL, Ruby on Rails, Laravel, and React are battle-tested. If you encounter a bug, ten thousand people have already asked about it on StackOverflow. That saves you weeks of development time.

Frontend and Backend Unification

Historically, companies built a separate React Single Page Application (SPA) that communicated with a separate Express or Python API. Today, the meta has shifted to full-stack web frameworks. Next.js (TypeScript), Laravel (PHP), and Ruby on Rails allow small or solo developer teams to build massive applications in a single codebase. By sharing types, routing, and data fetching logic across the frontend and backend, you eliminate entire classes of bugs and double your shipping speed.

When to deviate from the standard path?

You should only deviate from standard CRUD (Create, Read, Update, Delete) frameworks when your product explicitly demands it. If you are building a heavy generative AI application, you will need Python (FastAPI). If you are building a high-frequency trading bot, you will need Go or Rust. If you are building an offline-first mobile app, React Native or Flutter is mandatory. Do not optimize for edge cases you don't have yet.

Frequently Asked Questions

What is the most popular stack for indie hackers in 2025?

The 'T3 Stack' or variations of it dominate solo founders. Generally: Next.js (App Router), Tailwind CSS, TypeScript, PostgreSQL (via Prisma or Drizzle ORM), and authentication via Clerk or Supabase. It offers incredible velocity for solo devs.

Is No-Code viable for a real SaaS?

Yes. Many businesses generating six figures MRR are built entirely on Bubble or Webflow + Xano. No-Code is excellent for saving early capital, though you may need to rewrite in code (Next.js/React) once you hit massive scale or highly complex custom logic.

Why do you recommend PostgreSQL over MongoDB?

95% of SaaS applications deal in relational data (Users have many Posts, Posts have many Comments). PostgreSQL handles relational data perfectly, offers stringent data integrity, and now supports vector embeddings (pgvector) for AI, making it the superior choice over NoSQL defaults.

Should I build mobile apps native (Swift/Kotlin) or cross-platform?

Unless your app relies heavily on low-level device hardware (like complex 3D camera processing), cross-platform (React Native/Expo or Flutter) is the correct choice. It halves your development time and allows you to release to iOS and Android simultaneously.

Is Vercel/Heroku too expensive compared to AWS?

At massive scale, yes. But at the startup phase, developer time is your most expensive asset, not server costs. Paying a $20/mo premium to a PaaS (Platform as a Service) to avoid spending 10 hours a week doing DevOps is an incredibly high ROI decision.
