Are you a data scientist struggling to build web apps? You're likely using the WRONG framework! Forget the hype around Streamlit as the ONLY answer. This video dives deep into the REALITY of web app development for data scientists and engineers, exposing the bad advice and poor framework choices that lead to frustration.

🔥 Which framework is actually right for you?

◉ S-Tier: Need a quick app? Streamlit (but beware of its limits).
◉ A-Tier: Want more control? Dash or FastHTML might be better.
◉ B-Tier: Serious production apps? FastAPI + React (if you don’t mind suffering).
◉ C-Tier & Below: If you love debugging obscure tech.

Stop wasting time on the wrong tools! Watch as we break down the pros, cons, and pain points of popular web frameworks for data scientists—no sugarcoating.

Key Takeaways:
◉ Most data scientists DON'T actually want to build full web apps.
◉ Stop struggling with CSS in Dash or endless reloads in Streamlit for complex applications.
◉ Understand the different tiers of frameworks and choose wisely based on your REAL needs.
◉ Consider data presentation tools before jumping into web development.
◉ Sometimes, the best solution is to tell your company to hire a web developer!
