Right-click → View Source. Real HTML. No hydration markers.

Why Flask Vibe?

In 2026, AI assistants write half your code. Simple stacks win.

Faster by Design

No build step. No hydration. No JavaScript bundle. Flask serves HTML directly — 1.8× faster LCP than Next.js. Real users, real speed.

AI Loves It

Claude, ChatGPT, and Copilot write reliable code with raw SQL and vanilla JS. No ORM hallucinations. No framework magic.

View Source Works

Right-click → View Source shows actual HTML. Find bugs in 30 seconds. Debug without source maps. Verify AI output instantly.

The Complexity Problem

Modern frameworks promised simplicity. They delivered complexity.

Next.js Setup

📁 node_modules/ (300MB)

📄 package.json (50 dependencies)

⚙️ next.config.js

⚙️ tsconfig.json

⚙️ .eslintrc

📁 .next/ (build cache)

🔧 webpack, babel, swc...

5 minutes to install. 10 minutes to build. Debugging? Good luck tracing through transpiled, minified, server-rendered React.

Flask Setup

📄 app.py (15 lines)

📄 requirements.txt (3 deps)

📁 templates/

📁 static/

That's it.

30 seconds to install. No build step. Refresh browser, see changes. What you write is what runs.
