Flask Vibe
One developer's journey from YouTube tutorials to building apps with AI and Flask
Frederick Tubiermont
Founder, Flask Vibe
I started coding at 47 in 2022, learning Python like the kids do — YouTube tutorials, trial and error, first building local scripts for file processing, competitive intelligence research, and SEO.
When the OpenAI API launched in November 2022, I immediately jumped in. First came more complex backend scripts. Then I wanted to build real apps — full-stack, with a UI — and that's when I discovered Flask.
It was a revelation. Routes, templates, SQL. No magic. No build step. Just code that did exactly what I told it to.
Since then, I've watched vibe coders struggle with the default Next.js/React stack on platforms like Lovable, Base44, and Replit — fighting hydration errors, opaque ORMs, and configs they don't control. Flask doesn't do that to you.
Flask Vibe is me sharing what I've learned. If you're building AI-assisted apps and want to actually understand what you're shipping, this is for you.
The Journey
From YouTube tutorials to shipping real apps with Flask
Learning to Code
Started from zero — Python via YouTube, one tutorial at a time. When the OpenAI API launched in November 2022, jumped straight in: backend scripts, API wrappers, automation. Then wanted to build full apps with a real UI.
Discovered Flask. Never looked back.
Watching Others Struggle
Saw vibe coders on Lovable, Base44, and Replit fighting Next.js defaults — hydration errors, opaque ORMs, build configs they couldn't debug. Meanwhile, Flask + psycopg2 just worked. AI wrote the SQL, I read it, done.
The gap was obvious. Simple stacks win.
Flask Vibe — Just Launched
Built Flask Vibe to put everything in one place — tutorials, comparisons, real code. AI writes half the code now. The question is whether you understand what it wrote. With Flask, you do.
Day one. Let's go.
Our Mission
"Defend simplicity in the age of AI-assisted development."
Simplicity
Choose the simplest solution that solves the problem
Transparency
You should always know what's happening under the hood
Performance
Real users experience performance, not developer convenience
We believe that in 2026, with AI assistants writing half your code, simple stacks win. Flask + PostgreSQL + Vanilla JS is easier to generate, easier to verify, and easier to maintain.
We're not bashing other frameworks. We're defending a different path. A path where:
- You can read the SQL and know it's correct
- View Source shows real HTML, not hydration markers
- AI generates working code on the first try
- Pages load in milliseconds, not seconds
- You can understand the entire codebase in 5 minutes
This is Flask Vibe. This is our mission.
What's on This Site
Fresh launch — here's what's already here
Flask vs Next.js
Side-by-side code comparisons — form validation, database queries, template rendering. Real code, no cherry-picking.

Why simple stacks work better with AI — the feedback loop, the verification gap, and prompt templates that actually work.

Honesty Over Hype
We tell you when Flask isn't the right choice. We're not here to sell you a framework. We're here to help you build better software.
Education Over Evangelism
We teach principles, not dogma. We show you how Flask works and why it's simple, so you can make informed decisions.
Community Over Competition
We celebrate other frameworks when they're the right choice. We collaborate with Django, FastAPI, and even Next.js developers. Rising tide lifts all boats.
Code Over Slides
Every tutorial includes working code. Every comparison includes real benchmarks. No marketing. Just data and code you can run.

Max Dujean
Founder, SaaS startup · Brussels
"I switched a dashboard from Next.js to Flask. Load time went from 3.2s to 180ms. The entire codebase is 400 lines instead of 4,000. I can onboard a junior dev in one afternoon instead of one week. I'll never go back."
Sophie K.
Indie developer · London
"I'd been fighting Prisma migrations for two days. Switched to Flask + psycopg2 for my side project. Built the same feature in 45 minutes. The SQL was right there — I could read it and know it worked. That's the moment it clicked for me."
Thomas R.
Freelance developer · Paris
"My clients don't care about React. They care about features shipping on time. Flask lets me move twice as fast. I now quote lower prices than competitors and deliver faster. Flask Vibe explained exactly why this works — it's not just my imagination."
Anya L.
Data engineer turned web dev · Berlin
"Coming from data engineering, I know SQL. Flask just... gets out of the way and lets me use it. No ORM to fight. No migration files to manage. When Claude writes a psycopg2 query, I can tell immediately if it's right. That's worth everything."
