Heroku Alternatives for Python-based Applications

Last updated November 8th, 2022

Heroku changed how developers build and deploy software, making building, deploying, and scaling applications easier and faster. They set various standards and methodologies -- namely, the Twelve-Factor App -- for how cloud services should be managed, which are still highly relevant today for microservices-based and cloud-native applications. Unfortunately, starting November 28, 2022, Heroku will discontinue its free tier. This means you'll no longer be able to leverage free dynos, Postgres databases, and Redis instances.

For more on Heroku's discontinuation of its free product tiers, check out Heroku's Next Chapter and Deprecation of Heroku Free Resources.

In this article, you'll learn what the best Heroku alternatives (and their pros and cons) are.


What is Heroku?

Heroku, which was founded in 2007, is a cloud Platform as a Service (PaaS) that provides hosting for web applications. They offer abstracted environments where you don't have to manage the underlying infrastructure, making it easy to manage, deploy, and scale web applications. With just a few clicks you can have your app up and running, ready to receive traffic.

Before Heroku hit the scene, the process of running a web application was quite challenging, mostly reserved for seasoned SysOps professionals rather than developers. Heroku provides an opinionated layer, abstracting away much of the configuration required for a web server. The majority of web applications could (and still can) leverage such an environment, so smaller companies and teams can focus on application development rather than configuring web servers, installing Linux packages, setting up load balancers, and everything else that goes along with infrastructure management on a traditional server.

Heroku's Pros and Cons

Despite Heroku's popularity, it has received quite a lot of criticism throughout the years.

If you're already familiar with Heroku, feel free to skip this section.


Ease of Use

Heroku is arguably the most user-friendly PaaS platform. Rather than spending days setting up and configuring web servers and the underlying infrastructure, you simply define the commands required to run your web application and Heroku does the rest for you. You can literally have your app up and running in minutes!

Plus, Heroku leverages git for versioning and deploying apps, which makes it easy to deploy and roll back.

Finally, unlike most PaaS platforms, Heroku provides excellent error logs, making debugging relatively easy.


For the first five years of its existence, Heroku had few competitors. Their user/developer experience was just so far ahead of everyone else that it took a while for companies to adapt. This, coupled with their vast free tier, meant that the majority of developer-focused tutorials used Heroku for their deployment platform. Even to this day, the vast majority of web development tutorials, books, and courses still leverage Heroku for deployment.

Heroku also has first-class support for some of the most popular languages and runtimes (via buildpacks) like Python, Ruby, Node.js, PHP, Go, Java, Scala, and Clojure. While those are the officially supported languages, you can still bring your own language or custom runtime to the Heroku platform.

Integrations and Add-ons

Often overlooked, Heroku provides access to hundreds of add-on tools and services -- everything from data storage and caching to monitoring and analytics to data and video processing. With a click of a button, you can extend your app by provisioning a third-party cloud service all without having to manually install or configure it.


Heroku allows developers to easily scale their apps both vertically and horizontally. Scaling can be achieved via Heroku's dashboard or CLI. Additionally, if you're running more performant dynos you can leverage the free auto-scaling feature, which increases the number of web dynos depending on the current traffic.



Heroku is rather expensive compared to other PaaS on the market. While their starting plan is $7 per dyno per month, as your app scales, you're quickly going to have to upgrade to better dynos, which cost quite a lot of money. Due to the price of more performant dynos, Heroku might not be appropriate for large, high-traffic apps.

Heroku compared to AWS EC2 is about five times more expensive.

Keep in mind, though, that Heroku is a PaaS that does a lot of the heavy lifting for you, while EC2 is just a Linux instance that you have to manage yourself.

Lack of Control and Flexibility

Heroku doesn't offer enough control and lacks transparency. By using their service, you're going to be highly dependent on their tech stack and design decisions. Some of their limitations hinder scalability -- e.g., an application can only listen on a single port, functions have a max source code size of 500 MB, and there's no way to fine-tune your database. Heroku is also highly dependent on AWS, which means that if an AWS region is down, your service (hosted in that region) is also going to be down.

Similarly, Heroku is really designed for your run-of-the-mill RESTful APIs. If your app includes heavy computing or you need to tweak the infrastructure to meet your specific needs, Heroku may not be a good fit.

Lack of Regions

Heroku offers two types of runtimes:

  1. Common Runtime - for non-enterprise users
  2. Private Spaces Runtime - for enterprise users

The Common Runtime only supports two regions, US and EU, while the Private Spaces Runtime supports 6 regions.

This means that if you're not an enterprise user you'll only be able to host your app in the US (Virginia) or EU region (Dublin, Ireland).

$ heroku regions

ID         Location                 Runtime
─────────  ───────────────────────  ──────────────
eu         Europe                   Common Runtime
us         United States            Common Runtime
dublin     Dublin, Ireland          Private Spaces
frankfurt  Frankfurt, Germany       Private Spaces
oregon     Oregon, United States    Private Spaces
sydney     Sydney, Australia        Private Spaces
tokyo      Tokyo, Japan             Private Spaces
virginia   Virginia, United States  Private Spaces

Lack of New Features

In today's world, development trends change faster than ever. This forces hosting services to follow the trends to attract teams looking for cutting-edge technology. Many of Heroku's competitors, which we'll address here shortly, are advancing and adding new features like serverless, edge computing, etc. Heroku, on the other hand, has embraced stability over feature development. This doesn't mean they aren't adding new features; they are just adding new features much slower than some of their competitors.

If you want to see what's coming next to Heroku, take a look at their roadmap.

Lock In

Once you're running production code on Heroku it's difficult to migrate to a different hosting provider.

Keep in mind that if you move away from a PaaS, you'll have to handle all the things that Heroku handled yourself, so be prepared to make a SysAdmin or DevOps hire or two.

Heroku's Core Features

In this section, we'll look at Heroku's core features so you can understand what to look for as you look for alternatives.

Again, feel free to skip this section if you're already familiar with Heroku's features.

Feature Description
Heroku Runtime The Heroku Runtime is responsible for provisioning and orchestrating dynos, managing and monitoring the lifecycle of your dynos, providing proper network configuration, HTTP routing, log aggregation, and much more.
CI/CD system Easy-to-use CI/CD, which takes care of building, testing, deploying, incremental app updates, and more.
git-based deployments Manages app deployments with git.
Data persistance Fully-managed data services, like Postgres, Redis, and Apache Kafka.
Scaling features Easy-to-use tools that enable developers to scale horizontally and vertically on demand.

Collaboration features Easy collaboration with others. Collaborators can deploy changes to your apps, scale them, and access their data, among other operations.
Add-ons Hundreds of add-on tools and services – everything from data storage and caching to monitoring and analytics to data and video processing.

When looking for alternatives, you should prioritize the features. You're simply not going to find a 1:1 replacement for Heroku, so be sure to determine which features are "must-haves" vs "nice-to-haves".

For example:


  1. Solid UI
  2. Buildpacks
  3. git-based Deployments
  4. Battle-tested
  5. Simple scaling


  1. Application and Infrastructure Monitoring
  2. Uses AWS
  3. Free tier
  4. Add-ons
  5. CI/CD System

Heroku is a mature, battle-tested, and stable platform. It does a lot of heavy lifting for you and will save you a lot of time and money, especially for small teams. Heroku allows you to focus on your product instead of fiddling with your server's configuration options and hiring a DevOps engineer or SysAdmin.

It may not be the cheapest option, but it's still one of the best PaaS on the market. Because of that, if you're already using Heroku, you should have a strong reason to move away from it.

While there are a number of alternatives on the market, none of them match Heroku's developer experience. At the moment the most promising alternatives to Heroku are DigitalOcean App Platform and Render. The problem with these two platforms is that they are relatively new and not (yet) battle-tested. If you're just looking for a place to host your apps for free, go with Render.
