Python Frameworks in 2026: Django, Flask, FastAPI and 20+ Others by Category, and How to Choose

The most used Python web frameworks in 2026 are Django (full-stack), Flask (micro) and FastAPI (modern API framework). Choose Django for content-heavy or data-driven sites with admin and authentication built in, Flask for small apps and custom stacks, and FastAPI for typed, high-performance APIs. Many other frameworks exist, but several older ones are unmaintained, so check activity before you adopt one.

Key Takeaways

• JetBrains' State of Python 2025 article lists FastAPI at 38% (up 9 points) and Django at 35% (up 2) among surveyed developers. The year label in that article is inconsistent, so check the original report.
• Django's download page lists 5.2 LTS (latest 5.2.18, extended support to April 2028), 6.0 (6.0.9) and 6.1 (6.1.2). Flask's latest release was 3.1.3 on February 19, 2026, and it requires Python 3.9 or later.
• A framework gives you structure and calls your code. A library is code you call. Most projects use both.
• Prefer actively maintained projects with recent releases, clear documentation and a community, and check the license.
• Appic is a publisher with a commercial interest in Python development, so verify versions and status yourself.

What is a Python framework?

A Python framework is a set of tools and conventions that gives your application a structure, such as routing, request handling, templates, database access, security helpers and project layout. You fill in the parts that are specific to your product. Python is a general-purpose language released in 1991 by Guido van Rossum, and its frameworks cover web, APIs, data apps and more.

What is the difference between a framework and a library?

What are the types of Python frameworks?

• Full-stack frameworks include most things you need: ORM, templates, authentication, admin and forms. Django is the leading example.
• Microframeworks give routing and a core, and you add the rest. Flask, Bottle and Falcon are examples.
• Asynchronous and API-first frameworks are built for non-blocking I/O and typed APIs. FastAPI, Starlette, Sanic, aiohttp and Tornado are examples.

Which Python frameworks are worth knowing?

Mainstream choices

Other active options (check current status)

Older or niche frameworks (verify before use)

The earlier version listed CubicWeb, Pylons, Giotto, Growler, Morepath, Pycnic, web2py, Grok, BlueBream, Quixote, weppy and Zope. Several are legacy, merged into other projects or have little recent activity, as far as we know. Zope still underpins some content management systems. We did not check each one, so inspect the release history and issue tracker before you start a new project on any of them.

Sources for versions: Django downloads and Flask on PyPI. We could not load FastAPI's PyPI page for this update.

How popular are they?

JetBrains' State of Python 2025 article lists FastAPI at 38% of surveyed developers, up 9 points from the year before, and Django at 35%, up 2 points (JetBrains). The article's year labels are inconsistent, so treat the percentages as indicative. A separate Django Developer Survey 2024 reported Django as the preferred framework for 74% of Python developers, down from 83% the year before. Flask's figure was not in the results we saw. Secondary articles claim FastAPI passed Flask in GitHub stars, but we did not verify that. Popularity does not decide fit, so choose on your needs.

The earlier version said Django was the "second most popular" framework and quoted "15% of Stack Overflow questions" for 2021 without a source, so we removed both.

What do the main frameworks look like?

These minimal examples show the style of each. We did not run them, so test them in your own environment.

# Flask
from flask import Flask

app = Flask(__name__)

@app.get("/")
def home():
    return {"message": "Hello from Flask"}
# FastAPI
from fastapi import FastAPI

app = FastAPI()

@app.get("/")
async def home():
    return {"message": "Hello from FastAPI"}

FastAPI is usually run with an ASGI server such as Uvicorn. Django starts from a project generator (django-admin startproject mysite) and includes an admin, ORM and authentication.

How do you choose a Python framework?

1. Define the product and its main risks: scale, security, speed to market.
2. Check maintenance. Recent releases, active issues and supported Python versions.
3. Review the ecosystem. Authentication, ORMs, testing and deployment guides.
4. Consider your team. Choose what you can hire for and maintain.
5. Prototype one feature in your top two choices before you commit.

Appic is a publisher with a commercial interest, so compare quotes.

What changed from the earlier version of this post?

The January 2024 version had a 2025 title, a 2023 section heading and a 2024 conclusion, a list of 25 frameworks with no versions or maintenance status, many headings that did not match the framework described (such as "Receptacle", "Give a hug" and "Dream in Blue"), unsourced popularity and benchmark claims, no code and no FAQ. This update groups frameworks by type, adds current release data and survey figures with limits, simple code examples and a selection guide.
