React or Angular? Node or Python? AWS or Google Cloud? MySQL or MongoDB? If you’re a non-technical founder building a software product, the tech stack question feels overwhelming. This guide cuts through the noise with a simple decision framework.
The Most Important Principle: Follow the Team
The single most important factor in choosing a tech stack is what your development team knows well. A great developer in a familiar stack will always outperform a great developer learning a new one. If you’re hiring developers, hire for skills first — then accept the stack that comes with those skills. If you’re working with an agency, ask what they have deepest expertise in and why.
Our Default Recommendation for Web Apps
For most web applications in 2025: React (Next.js) + Node.js or Laravel + PostgreSQL + AWS.
- React/Next.js: Largest talent pool, excellent performance, good for SEO with server-side rendering.
- Node.js or Laravel backend: Node.js if your team knows JavaScript and you want one language. Laravel if speed of development and built-in features matter more.
- PostgreSQL: Relational database for 90% of use cases. ACID compliant, strong typing, excellent performance, JSON support. Start here unless you have a specific reason not to.
- AWS: Industry standard. Most integrations, compliance frameworks, and the widest DevOps hiring pool.
Mobile: Flutter or React Native
For cross-platform (iOS + Android) from one codebase: Flutter for best performance and design flexibility, React Native if your team knows JavaScript. Native Swift (iOS) or Kotlin (Android) only when you need hardware capabilities that cross-platform genuinely can’t provide.
Database Guide
- PostgreSQL (default): Structured data, relationships between entities, transaction requirements — start here.
- MongoDB: Genuinely document-like data, highly variable schema, storing third-party API JSON. Often overused — most “NoSQL is better” arguments don’t hold for typical business apps.
- Redis: Not a primary database. Cache layer, session storage, real-time leaderboards. Used alongside PostgreSQL.
- Elasticsearch: Full-text search at scale — when PostgreSQL’s built-in search reaches its limits (~1M+ records with complex search needs).
5 Questions to Answer Before Deciding
- Does my product need real-time features? Live chat, collaborative editing → Node.js backend.
- Do I need SEO? → Next.js (React SSR) or Nuxt (Vue SSR).
- What are my compliance requirements? HIPAA, PCI-DSS, SOC 2 affect infrastructure choices.
- How quickly do I need to ship? Speed favours batteries-included frameworks (Laravel, Django) over minimal ones (Express, Flask).
- What does my team know? This trumps everything above.
Mistakes to Avoid
- Choosing based on Hacker News trends. Hype ≠ production-readiness.
- Cool new framework over proven ones. For products that need shipping and maintenance, boring and proven beats exciting and immature.
- Over-engineering from day 1. Microservices, Kubernetes, and event-driven architecture solve problems you probably don’t have yet. Build the simplest thing that works.
- Ignoring hosting costs at scale. Some frameworks have dramatically different infrastructure costs with growth.
