What is a Tech Stack? Explained for Non-Technical Founders

What is a Tech Stack?

A tech stack is the combination of technologies used to build an application. It includes the programming languages, frameworks, databases, and tools that make up your product.

The Layers of a Tech Stack

Frontend (What Users See)

• HTML, CSS, JavaScript
• Frameworks: React, Vue, Next.js
• Styling: Tailwind CSS

Backend (Behind the Scenes)

• Languages: Node.js, Python, Go
• Frameworks: Express, Django, FastAPI
• APIs and business logic

Database (Where Data Lives)

• PostgreSQL, MySQL (relational)
• MongoDB (document)
• Redis (cache)

Infrastructure (Where It Runs)

• Hosting: Vercel, AWS, Google Cloud
• CDN: Cloudflare
• Monitoring: Datadog

Common Tech Stacks

MERN Stack

• MongoDB, Express, React, Node.js
• Good for: JavaScript-focused teams

JAMstack

• JavaScript, APIs, Markup
• Good for: Fast, static sites

Next.js + Supabase

• React framework + managed backend
• Good for: Full-stack apps, used by Spawned

Python + Django

• Traditional, reliable
• Good for: Data-heavy apps, ML integration

What Non-Technical Founders Should Know

What Matters

• Scalability: Can it grow with you?
• Hiring: Can you find developers?
• Cost: What's the ongoing expense?
• Speed: How fast can you build?

What Doesn't Matter (Early On)

• Trendy vs boring tech
• Theoretical performance limits
• Complex architecture
• "Future-proofing"

Choosing a Tech Stack

If You're Building with AI (Spawned)

You don't need to choose—the AI selects appropriate technologies:

• React for frontend
• Supabase for backend
• Tailwind for styling
• Vercel for hosting

If You're Hiring Developers

Let your technical co-founder or first engineer decide. They'll use what they know best.

General Advice

• Use boring, proven technology
• Prioritize speed to market
• Don't over-engineer early
• You can always change later

Questions to Ask Technical People

Good Questions

• "How long will this take to build?"
• "What are the ongoing costs?"
• "How hard is it to find developers for this?"
• "Can this scale to 10K users? 100K?"

Less Useful Questions

• "Is this the newest technology?"
• "What does [big company] use?"
• "Is this enterprise-grade?"

Key Takeaways

1. Tech stack = tools used to build your app
2. For non-technical founders, focus on speed and cost
3. AI builders like Spawned make this decision for you
4. Boring, proven technology beats trendy
5. You can change technology later if needed
