Smarter Choices for Building Scalable Web Apps
Summary: Heading towards 2026,
Python continues to be a force to reckon with in web development. Being the
easiest to learn, most readable, and feature-wise best ecosystem to do so,
developers are working with Python frameworks and packages more than ever before
to develop anything from mere APIs to full-scale enterprise platforms. But not
all frameworks are the same, and the framework you do stick with will,
therefore, affect your development speed, scale for the future, and
maintainability of your code in your codebase. Here we will be talking about
five of the rising Python web frameworks for 2025 worthy of watching. If you
are an independent freelance developer, a first-time development team, or a new
tech start-up, this article should have everything you need to make an informed
decision about your next web development project.
Introduction:
There are so many frameworks out
there. In fact, if you are using Python, it could be overwhelming thinking
about which one to get started with: full-stack, micro, async-ready, modular,
or somewhere in between. But the truth is: not every project is going to be
built the same. This is exactly why getting to know the advantages of each
Python web framework is so important in 2025.
Whether you are building a cool
front-facing application or just designing the backend infrastructure, the
framework you go with could save you months in development work. Again, this is
a big part of why a top Python
development company has a competitive advantage: they are able to select the
right tool for the job.
In this blog, we will cover five
of the best frameworks to work with Python
web app development in 2025. These five frameworks are not just fads: they
are used in the real world, are stable, and have active communities behind them.
By the end of the blog, you will have an idea of the framework you would like
to adopt as well as how to use it effectively.
1.
FastAPI: The API Platform with Speed
FastAPI is not just called
FastAPI; it is fast when it counts. FastAPI transitioned from introduction in
2018 to mainstream development at lightning speed because of its async
architecture, its clean structure, and fantastic development capabilities.
So, while it should be no
surprise in 2025, we’re really only going to highlight two reasons why FastAPI
continues to stand out.
●
Built for
Speed: Utilizing Starlette and async Python, FastAPI provides performance to
handle tens of thousands of connections simultaneously. FastAPI's performance
is ideal for today's development environments, i.e., IoT back-ends involving
microservices, real-time dashboards, etc.
●
Neat Type
Hints = Very Few Bugs: FastAPI utilizes Python type hints to automatically
validate and throw run-time errors.
●
Automatic
Documentation: Built-in Swagger and ReDoc documentation is auto-generated and
interactive, making it very quick to go from testing APIs to documenting
handovers.
FastAPI is especially appealing
for organizations providing Python web
development services that prioritize speed, scalability, and clear
communication of data.
2.
Django: The Universal Workhorse that just won't die - and continues to improve!
Django is still going strong, and
better! In 2025, Django 5.0 continues to be a proud member of the Python web
framework community, equipped with some improved async support optimizations,
better ORM query speeds, and enhanced project config capabilities. If you're in
any development capacity and need to build easily scalable web platforms,
Django is still the best framework for the job.
Here is why Django is still number
one:
●
Complete
Toolbelt: Django comes complete with everything you need to get a robust web
app up and running: ORM, templating engine, form handling, admin panel, etc.
The aggregate of these items allows developers to focus on building instead of
having to deal with obnoxious package installations.
●
Robust
built-in security: Because Django has a long list of built-in protections
against common web threats, developers have the luxury of focusing on
integrations and being less concerned about hardening their applications
against threats.
●
Comprehensive
ecosystem: From Django REST Framework (DRF) to Celery, to channels for
real-time interaction, and everything else, Django has it all. All of these are
mature products, and there are tons of great resources in the wild for building
production systems.
When you are in a top Python
development company,
Django is the framework you usually try to first branch out from. It's easy to
get rolling if you are building software as a service (SaaS), or an MVP, or
some other type of application; Django will just work.
3.
Flask: The Adaptable Light Weight Veteran That Keeps Changing
Flask will survive and thrive in
2025. Flask is Ms. P for me. Flask's "do-it-your-way" approach
appeals to developers who want control over every part of their application.
Reasons why Flask will continue
to boom in 2025:
●
Minimal Core
= Max Freedom: Flask doesn't impose structure, so you can build your
application however it makes sense to you.
●
Extensible
Ecosystem: Authentication? No problem! Caching? Where's a plug-in? Email? I've
got a feeling they have one! If you want to roll your own solution to any of
these aspects, you can roll your own solution!
●
It is easy
to learn: It is easy to use if you do not have a ton of experience with
developing the backend, but also powerful for more advanced solutions.
Many teams, building custom
Python web app solutions, would use Flask as the development framework simply
because a full-stack framework would create unnecessary overhead for a simple
custom solution.
4. Sanic:
The Async-First Framework Built for Real-Time Performance
Sanic may not be vibrant, but
Sanic is fast. Sanic was one of the first Python frameworks to leverage the
async/await paradigm into its structure, and in 2025, Sanic was designed for
developers who want speed and real-time capability built into the framework
from the start.
Why Sanic is Different:
●
Performance
metrics: In the most recent benchmark tests, Sanic achieved approximately
110,000 requests per second on a clean testing machine that was only forwarding
requests and with some sub-millisecond latencies.
●
Real Time
Capabilities: Sanic has native support for web-sockets, stream responses, and
HTTP/2, so it is the best web framework to work with in regard to using
streaming or real-time data.
●
Granular
middleware and routing: You can control every layer of your request/response
runtime and optimize everything.
If you are in FinTech, gaming, or
developing a traditionally highly interactive product, hiring Python developers
with Sanic experience can have a serious impact on your performance.
5.
Pyramid: The Quiet Leader for Complex Architectures
It is not widely used out there,
like Django or FastAPI, but Pyramid's story is changing, and with the newly
introduced plugin architecture that enables asynchronous integration and
aspirations to promote maintainable components, Pyramid is seeing a resurgence
in popularity with enterprise engineers in 2025.
When Pyramid is highly useful:
●
Scale as you
grow: You can start to build, then you can use Pyramid's modular approach to
build a small application into a larger application or a multi-layered
application.
●
Customize:
You can use your choice of template engine: Jinja2 or Chameleon.
●
You can
choose your DB: ORM with SQLAlchemy or NoSQL LM with MongoDB.
●
Prime for
the Enterprise: Pyramid is largely utilized for internal tools, CMS, and
workflows when you want to hold accounts to smaller levels of detail.
If you are looking to find Python web development companies that
can build scalable software operations for the years to come, Pyramid is
certainly worth consideration as a viable framework option.
Final
Take
The reality
is that each of these Python frameworks has a sweet spot:
●
Try FastAPI
if you're working on an API that's designed to maximize speed, particularly if
you're making an API for AI or microservices.
●
Try Django
if you're looking for a full-stack experience, loads of out-of-the-box helpers,
and the strongest long-term backwards compatibility.
●
Try Flask
when you'd like to have the most flexibility and least "magic" or
conventions.
●
Utilize
Sanic when building performance-critical real-time applications that require
async all the way down.
●
Utilize
Pyramid when you are building something that is complex and large, and when you
want 100% control over your project.
Regardless
of what you are building, working with talented and experienced developers
makes a world of difference. Whether you are looking for Python web development services or you are beginning to hire Python developers, your knowledge
about these frameworks will enhance your collaboration and expectation
management.
The top Python web development companies in
2025 do not simply use only one of these tools; they thoughtfully select and
choose the tool that is right for the task at hand. Now you can too.
