Django is Boring, or Why Tech Startups (Should) Use Django

I recently attended Django Under The Hood in Amsterdam, an annual gathering of Django core team members and developers from around the world. A common theme discussed at the conference this year is that “Django is boring.” While it’s not the first time this has been discussed, it still struck me as odd. Upon further reflection, however, I see Django’s “boringness” as a huge asset to the community and potential adopters of the framework.

Caktus first began using Django in late 2007. This was well before the release of Django 1.0, in the days when startups and established companies alike ran production web applications using Subversion “trunk” (akin to the Git “master” branch) rather than using a released version of the software. Using Django was definitely not boring, because it required reading each commit merged to see if it added a new feature you could use and to make sure it wasn’t going to break your project . Although Django kept us on our toes in the early days, it was clear that Django was growing into a robust and stable framework with hope for the future.

With the help of thousands of volunteers from around the world, Django’s progressed a lot since the early days of “tracking trunk.” What does it mean that the people developing Django itself consider it “boring,” and how does that change our outlook for the future of the framework? If you’re a tech startup looking for a web framework, why would you choose the “boring” option? Following are several reasons that Caktus still uses Django for all new custom web/SMS projects, reasons I think apply equally well in the startup environment.

1. Django has long taken pride in its “batteries included” philosophy.

Django strives to be a framework that solves common problems in web development in the best way possible. In my original post on the topic nearly 8 years ago, some of the key features included with Django were the built-in admin interface and a strong focus on data integrity, two features missing from Ruby on Rails, the other major web framework at the time.

Significant features that have arrived in Django since that time include support for aggregates and query expressions in the ORM, a built-in application for geographic applications (django.contrib.gis), a user messages framework, CSRF protection, Python 3 support, a configurable User model, improved database transaction management, support for database migrations, support for full-text search in Postgres, and countless other features, bug fixes, and security updates. The entire time, Django’s emphasis on backwards compatibility and its generous deprecation policy have made it perfectly reasonable to plan to support and grow applications over 10 years or more.

2. The community around Django continues to grow.

In the tradition of open source software, users of the framework new and old support each other via the mailing list, IRC channel, blog posts, StackOverflow, and cost-effective conferences around the globe. The ecosystem of reusable apps continues to grow, with 3317 packages available on as of the time of this post.

A common historical pattern has been for apps or features to live external to Django until they’re “proven” in production by a large number of users, after which they might be merged into Django proper. Django also recently adopted the concept of “official” packages, where a third-party app might not make sense to merge into Django proper, but it’s sufficiently important to the wider Django community that the core team agrees to take ownership of its ongoing maintenance.

The batteries included in Django itself and the wealth of reusable apps not only help new projects get off the ground quickly, they also provide solutions that have undergone rigorous code review by experts in the relevant fields. This is particularly important in startup environments when the focus must be on building business-critical features quickly. The last thing a startup wants to do, for example, is focus on business-critical features at the expense of security or reliability; with Django, one doesn’t have to make this compromise.

3. Django is written in Python.

Python is one of the most popular, most taught programming languages in the world. Availability of skilled staff is a key concern for startups hoping to grow their team in the near future, so the prevalence of Python should reassure those teams looking to grow.

Similarly, Python as a programming language prides itself on readability; one should be able to understand the code one wrote 6-12 months ago. Although this is by no means new nor unique to Django, Python’s straightforward approach to development is another reason some developers might consider it “boring.” Both by necessity and convention, Python espouses the idea of clarity over cleverness in code, as articulated by Brian Kernighan in The Elements of Programming Style. Python’s philosophy about coding style is described in more detail in PEP 20 -- The Zen of Python. Leveraging this philosophy helps increase readability of the code and the bus factor of the project.

4. The documentation included with Django is stellar.

Not only does the documentation detail the usage of each and every feature in Django, it also includes detailed release notes, including any backwards-incompatible changes, along with each release. Again, while Django’s rigorous documentation practices aren’t anything new, writing and reading documentation might be considered “boring” by some developers.

Django’s documentation is important for two key reasons. First, it helps both new and existing users of the framework quickly determine how to use a given feature. Second, it serves as a “contract” for backwards-compatibility in Django; that is, if a feature is documented in Django, the project pledges that it will be supported for at least two additional releases (unless it’s already been deprecated in the release notes). Django’s documentation is helpful both to one-off projects that need to be built quickly, and to projects that need to grow and improve through numerous Django releases.

5. Last but not least, Django is immensely scalable.

The framework is used at companies like EventBrite, Disqus, and Instagram to handle web traffic and mobile app API usage on behalf of 500M+ users. Even after being acquired by Facebook, Instagram swapped out their database server but did not abandon Django. Although early startups don’t often have the luxury of worrying about this much traffic, it’s always good to know that one’s web framework can scale to handle dramatic and continuing spikes in demand.

At Caktus, we’ve engineered solutions for several projects using AWS Auto Scaling that create servers only when they’re needed, thereby maximizing scalability and minimizing hosting costs.

Django into the future

Caktus has long been a proponent of the Django framework, and I’m happy to say that remains true today. We established ourselves early on as one of the premiere web development companies specializing in Django, we’ve written previously about why we use Django in particular, and Caktus staff are regular contributors not only to Django itself but also to the wider community of open source apps and discussion surrounding the framework.

Django can be considered a best of breed collection of solutions to nearly all the problems common to web development and restful, mobile app API development that can be solved in generic ways. This is “boring” because most of the common problems have been solved already; there’s not a lot of low-hanging fruit for new developers to contribute. This is a good thing for startups, because it means there’s less need to build features manually that aren’t specific to the business.

The risk of adopting any “bleeding edge” technology is that the community behind it will lose interest and move on to something else, leaving the job of maintaining the framework up to the few companies without the budget to switch frameworks. There’s a secondary risk specific to more “fragmented” frameworks as well. Because of Django’s “batteries included” philosophy and focus on backwards compatibility, one can be assured that the features one selects today will continue to work well together in the future, which won’t always be the case with frameworks that rely on third-party packages to perform business-critical functions such as user management.

These risks couldn’t be any stronger in the world of web development, where the framework chosen must be considered a tried and true partner. A web framework is not a service, like a web server or a database, that can be swapped out for another similar solution with some effort. Switching web frameworks, especially if the programming language changes, may require rewriting the entire application from scratch, so it’s important to make the right choice up front. Django has matured substantially over the last 10 years, and I’m happy to celebrate that it’s now the “boring” option for web development. This means startups choosing Django today can focus more on what makes their projects special, and less on implementing common patterns in web development or struggling to perform a framework upgrade with significant, backwards-incompatible changes. It’s clear we made the right choice, and I can’t wait to see what startups adopt and grow on Django in the future.
