Django vs Flask Which Should You Learn First in 2026?

# app.py  - run: flask --app app run
from flask import Flask, jsonify

app = Flask(__name__)

@app.get("/")
def home():
    return "Hello from Flask!"

@app.get("/api/status")
def status():
    return jsonify(status="ok")

# One-time setup:
#   pip install django
#   django-admin startproject mysite && cd mysite
#   python manage.py startapp core

# core/views.py
from django.http import HttpResponse, JsonResponse

def home(request):
    return HttpResponse("Hello from Django!")

def status(request):
    return JsonResponse({"status": "ok"})

# mysite/urls.py
from django.urls import path
from core import views

urlpatterns = [
    path("", views.home),
    path("api/status", views.status),
]
# run: python manage.py runserver

# notes/models.py
from django.db import models

class Note(models.Model):
    title = models.CharField(max_length=120)
    body = models.TextField(blank=True)
    created = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.title

# notes/admin.py
from django.contrib import admin
from .models import Note
admin.site.register(Note)

# then: python manage.py makemigrations && python manage.py migrate
# and:  python manage.py createsuperuser  -> edit notes at /admin

# pip install flask flask-sqlalchemy
from datetime import datetime
from flask import Flask, jsonify, request
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config["SQLALCHEMY_DATABASE_URI"] = "sqlite:///notes.db"
db = SQLAlchemy(app)

class Note(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(120), nullable=False)
    created = db.Column(db.DateTime, default=datetime.utcnow)

@app.post("/notes")
def add_note():
    note = Note(title=request.json["title"])
    db.session.add(note)
    db.session.commit()
    return jsonify(id=note.id), 201

with app.app_context():
    db.create_all()

# pip install djangorestframework
# notes/serializers.py
from rest_framework import serializers, viewsets
from .models import Note

class NoteSerializer(serializers.ModelSerializer):
    class Meta:
        model = Note
        fields = ["id", "title", "body", "created"]

class NoteViewSet(viewsets.ModelViewSet):
    queryset = Note.objects.order_by("-created")
    serializer_class = NoteSerializer

# urls.py
# from rest_framework.routers import DefaultRouter
# router = DefaultRouter(); router.register("notes", NoteViewSet)
# urlpatterns += router.urls

# Serving a trained model with Flask
import joblib
from flask import Flask, jsonify, request

app = Flask(__name__)
model = joblib.load("model.joblib")      # trained scikit-learn model

@app.post("/predict")
def predict():
    features = request.get_json()["features"]   # e.g. [5.1, 3.5, 1.4, 0.2]
    pred = model.predict([features])[0]
    return jsonify(prediction=str(pred))

Answer yes or no:

[ ] I want to build full web apps with users and an admin
[ ] Job listings I want mention Django
[ ] I prefer clear conventions over many choices

[ ] I mainly want APIs or model-serving endpoints
[ ] I want to understand web basics step by step
[ ] I like choosing my own libraries
