Flask

ELI5 — The Vibe Check

Flask is the lightweight Python web framework — the 'just enough' option. It doesn't come with an ORM, admin panel, or auth system by default. You add what you need. If FastAPI is too much and you want something tiny and flexible, Flask is your friend.

Real Talk

Flask is a lightweight, WSGI-compatible Python web framework that provides minimal core functionality (routing, request handling, templating) without enforcing project structure or requiring specific components. Highly extensible via plugins. The microframework predecessor to modern Python APIs.

from flask import Flask, jsonify

    return jsonify({'message': 'Hello World'})
