Build Real Startups, Not Toy Projects.
Learn how famous startup ideas are built — by implementing the core MVP systems with AI, real code, and real tradeoffs.
Instagram-style social apps. AI journal apps. Hyper-local ad platforms.
We build the engine, not the polish.
What is Serious Vibe Coder?
Serious Vibe Coder is a tutorial platform where you learn by building the core system behind real startups.
No todo apps. We skip the tutorials that teach basics.
No fake demos. Every example runs real code on real infrastructure.
No over-engineered infra. We explain constraints, not add them.
Every project answers one question:
"Why does this startup work — technically?"
How It Works

Choose from curated starter projects inspired by real, successful startups.
Build the Core MVP
We implement only the essential features:
- • Data models
- • System logic
- • AI reasoning
- • Core flows
Everything else is intentionally skipped.
Understand the Tradeoffs
Learn:
- • What's faked
- • What's simplified
- • What breaks at scale
- • How real companies evolve
Starter Projects

Our Philosophy
How we think. How we build. How we teach.
Features vs Systems
We don't teach features. We teach systems.
Scale Awareness
We don't chase scale. We explain why scale breaks.
Core Logic
We don't copy startups. We extract their core logic.
