Choosing the Right Tech Stack for Custom Software in 2025
React vs Vue. Node vs Go. Postgres vs MongoDB. We share the decision framework we use when architecting software that needs to last 5+ years.
Choosing the Right Tech Stack for Custom Software in 2025
The tech stack you choose in week one will shape your product for the next five years. Get it wrong, and you'll spend years fighting your tools. Get it right, and shipping becomes effortless. Here's the framework we use with every client.
The four questions that matter
1. What's the team's existing expertise? The best stack is one your team already knows. A mediocre team with a familiar stack beats a genius team learning a new one.
2. How big will this get? A side project with 100 users has different needs than a SaaS targeting 100,000. Don't over-engineer early, but don't pick a stack that won't scale.
3. What's the hiring market? If you'll need to hire 10 engineers next year, pick a stack with a deep talent pool. Obscure stacks = expensive hires.
4. What's the ecosystem? Libraries, tutorials, Stack Overflow answers, AI assistant training data — all of this matters more than micro-benchmarks.
Our default stack (and why)
For most web products in 2025, we recommend:
Frontend: Next.js + TypeScript + Tailwind CSS
- React is the dominant UI library
- Next.js handles routing, SSR, and deployment
- TypeScript catches bugs at build time
- Tailwind makes design changes fast
Backend: Node.js (or Python for AI-heavy work)
- Same language as frontend = full-stack engineers
- Massive ecosystem via npm
- Great for API-first development
Database: PostgreSQL
- Rock-solid, 30 years of battle-testing
- JSON columns for flexible data
- Great hosting options (Neon, Supabase, RDS)
Hosting: Vercel (small teams) or AWS (enterprise)
- Vercel: zero-config, perfect for Next.js, generous free tier
- AWS: more work, but cheaper at scale and more flexible
When to deviate
Use Python instead of Node when:
- Heavy ML/AI workloads
- Data science is core to the product
- Scientific computing
Use Go instead of Node when:
- High-concurrency services (10K+ requests/sec)
- CLI tools and infrastructure
- Performance is critical
Use Flutter instead of React Native when:
- You need pixel-perfect design across iOS/Android
- Team has Dart experience
- Building complex animations
Stacks to avoid in 2025
- PHP without Laravel: legacy at this point
- Ruby on Rails for new projects: great framework, shrinking talent pool
- Any framework with <100K weekly npm downloads: ecosystem risk
The honest truth
For 90% of products, the stack choice doesn't matter as much as execution. A well-built PHP app will outperform a poorly built Next.js app every time. Pick a stack that lets your team move fast, and focus on the product.
