published on 16 December 2023

Developers often rely on Heroku for convenient app hosting, but may find its restrictions and costs prohibitive.

Thankfully, capable open source alternatives to Heroku exist that provide more customization, control, and potential cost savings.

This article explores Heroku limitations and introduces leading self-hosted solutions like Dokku, CapRover, and Cloudron that developers should consider in 2023.

Introduction to Heroku and Its Open Source Competitors

What is Heroku and Who Uses It

Heroku is a popular platform-as-a-service (PaaS) that allows developers to deploy, manage, and scale web applications without having to worry about configuring and managing servers. It provides key features like automated provisioning and scaling, deployment pipelines, and add-ons that make it easy for teams to get applications up and running quickly.

Heroku gained traction among startups and smaller development teams who did not want to deal with infrastructure management. Its ease of use, flexibility, and seamless integration with languages like Ruby, Node.js, Java, PHP and Python fueled rapid adoption. Brands like Toyota, Verizon, and Facebook leveraged Heroku in their early stages.

The Draw of Heroku Alternatives Free in 2023

As Heroku usage grows, teams often encounter drawbacks like lack of visibility and control, strict routing requirements, and increasing costs at higher scales. This drives interest toward open source PaaS alternatives that offer greater transparency, customization and more affordable pricing models.

Leading self-hosted solutions like Dokku, CapRover and Flynn provide similar capabilities to Heroku but give users full access to the source code. Developers have finer-grained control to optimize performance, costs and reliability. Integrations are also easier without restrictions posed on custom buildpacks and databases. Most open source options support Docker deployment allowing flexibility across languages and frameworks like Heroku alternatives for Node JS free.

With powerful open source PaaS platforms now freely available, many see a viable path to replicating Heroku's convenience without costly vendor lock-in or feature limitations in 2023.

Is there a free alternative to Heroku?

Heroku is a popular platform for deploying web applications, but it is not free to use. Here are some open source alternatives that provide free tiers:

Dokku

Dokku is a self-hosted Platform-as-a-Service that allows you to run your applications on your own server, similar to Heroku. It is open source and completely free to use.

Some key features:

  • Deploy apps using git push just like Heroku
  • Supports multiple languages including Node.js, Ruby, Python, Java, PHP
  • Easy to install on a Linux or MacOS server
  • Horizontal scaling with multiple dynos
  • Plugin system to extend functionality

The main downside is that you need to manage your own server. But overall Dokku provides a Heroku-like experience for free.

CapRover

CapRover markets itself as "private Heroku on any server". It offers a very similar developer experience as Heroku and has support for common buildpacks too.

Benefits of CapRover:

  • Deploy using Git, WebSocket logs, CLI tool
  • One-click HTTPS with Let's Encrypt
  • Dashboard to manage apps
  • Easy backup and migration

While not as fully featured as Heroku, CapRover makes it simple to self-host apps on a Linux server with Heroku-like convenience.

So in summary, both Dokku and CapRover offer free and open source self-hosted alternatives to Heroku's paid plans. For developers who want Heroku's simplicity without the cost, these projects allow setting up comparable PaaS functionality on your own infrastructure.

Is Heroku still free in 2023?

With Heroku's recent changes to remove their free Dyno tier, many developers are wondering if Heroku still has free options available in 2023.

The short answer is no - Heroku no longer offers any free service tiers. As of November 28th, 2022, all Heroku apps must be on paid Dyno types, which start at $7/month.

This is a major shift from Heroku's previous business model which relied heavily on a generous free tier to attract new users. Under the free tier, apps could run on a single Dyno for 18 hours/day without any charge. This made Heroku hugely popular for hosting small projects, prototypes, MVPs, and hobby apps.

However, managing resource usage across so many free accounts ultimately proved challenging to scale and sustain as a business. So now to continue using Heroku in 2023 and beyond, all accounts must be upgraded to a paid subscription.

For developers with low traffic apps seeking a Heroku alternative, some popular open-source options to consider include:

  • CapRover
  • Dokku
  • Fly.io
  • Render
  • Railway

These self-hosted platforms can closely replicate the Heroku experience, often with more flexibility around customization and resources. The main trade-off is that they do require managing your own server infrastructure.

So in summary - the Heroku free tier is gone for good as of late 2022. The platform still offers excellent managed container hosting and seamless deployment, but now strictly as a paid service. Developers have begun migrating to alternative solutions that remain free for smaller workloads.

Is Heroku no longer free?

Yes, unfortunately Heroku is no longer offering their free tier starting November 28th, 2022. This means some key free features of Heroku will no longer be available, including:

  • Free Heroku Dynos for hosting apps
  • Free Postgres databases
  • Free Redis add-ons

Heroku made this change due to the underlying costs associated with providing free services at scale. However, this takes away an easy starting point for developers just getting started with deployments.

There are some open source alternatives to Heroku that still offer free tiers for small projects, such as:

  • Dokku: Self-hosted mini-Heroku. Lets you run apps using Docker containers and Heroku buildpacks. Free and open source.

  • CapRover: Another self-hosted PaaS like Heroku focused on ease of use. Offers a free tier for testing.

So while Heroku itself no longer offers free hosting, the open source community has created Heroku-compatible platforms you can run yourself for free. For larger or commercial applications, there are affordable paid tiers on platforms like Render and Railway that can replace Heroku.
