The best Heroku alternatives in 2021

Heroku is one of the novel providers of Platform as a Service, also known as PaaS. Before the emergence of cloud services, developers are compelled to build and configure backend servers independently. They also have to deal with the limitations of shared hosting and the challenges of scaling the backend.  In fact, the challenges of cloud hosting and deployment were overwhelming for developers.  However, Heroku’s PaaS brought much-needed relief for developers, and the demand for  PaaS surged like wildfire among developers.  

Heroku is undoubtedly an industry leader. Despite the fast-paced change in technology, the company is still a pacesetter in the commercial cloud service industry.  Over the years, PaaS service from Heroku has been a bedrock for many technology companies. However, other companies offering similar services as Heroku have emerged over time. That is why many developers are researching alternatives to Heroku. 

This article explains the reason why developers are keen on alternatives to Heroku. We shall also explore various alternatives to Heroku with a focus on each platform’s strengths and weaknesses. 

Why Search for Heroku Alternatives?

The main reasons why developers are researching for Heroku alternatives are the challenge of high costs and sleeping apps. Let’s take a look at these issues one after the other.

Limited Datacenter Locations

Heroku has only two options for application deployment:

  • USA – North Virginia
  • Europe – Ireland

For more information about Heroku’s regions, please refer to this StackOverflow post. Depending on your region and how low you need your latency to be, it may be a limiting factor in using Heroku.

High Costs

The cost of Heroku can be on the high side when you need to scale your cloud service.  Heroku charges users based on the number of dynos they use. Unfortunately, the cost of using more dynos increases significantly as an app starts scaling.  

The issue related to the high costs of scaling apps on Heroku is a significant concern about the Heroku cloud service.  However, the downward review of the cost of a cloud service is a delicate issue. For instance, Heroku incurs service costs because it uses the third-party AWS infrastructure to deploy apps. So, a downward review of service charges may undermine the profitability of the company.

Sleeping apps

Although Heroku offers a free tier, it does come with limited resources and the challenge of the app “going to sleep”. After a period of inactivity, the app sleeps and becomes unavailable until the next request wakes it up. Heroku put apps to sleep to save server resources, but this state delays the app response by up to 20 seconds.

This feature is detrimental to both casual and professional developers who use the free tier to test apps and evaluate Heroku. Other users are compelled to upgrade to a premium plan where the price increases significantly as the app scales.

The Benefits of Heroku

Ease of Use: It is relatively easy to get the Heroku platform up and running. In fact, it takes less than five minutes for a complete beginner to set up an app on Heroku.  The developer often needs to run a couple of Git commands to bring an app online on this platform. Heroku also has extensive documentation that serves as a step-by-step guide.

Error Log: Heroku displays a standard error log when a deployment fails.  Most other platforms do not have this feature, making it challenging to troubleshoot failed installations. In essence, app deployment and debugging are easier on Heroku compared to other Platform as a Service. 

Extensive Add-Ons: Developers on Heroku can access a wide array of services and plugins ranging from database to mail functions. Heroku can inject these add-ons into instances on the fly, negating the need to install services manually.  

Scalability: Heroku allows its users to scale their apps quickly. The scaling app procedure requires a mere increase in the number of available dynos for an app instance. Heroku provides a web user interface and a command-line tool for scaling apps without hassles. 

Dedicated Server:  Heroku users can host apps on dedicated servers that offer standby server resources for apps. This reliable server option guarantees resource availability, preventing issues like “out of memory” failures while deploying apps.

Vast Experience: Heroku is among the pioneer PaaS providers with an excellent reputation among developers for its reliability.  Besides, Heroku provides extensive materials such as guides, articles, and tutorials designed for new users and experienced developers.

Free Plan:  The Free plan of Heroku offers a single dyno, 100-megabyte swap space, and 512MB RAM. This plan is suitable for casual developers and others who like to evaluate the platform.

SQL Offerings: Heroku users can access regular SQL, a feature that is not available with most PaaS providers. 

Pricing Structure: The pricing structure of Heroku is located within the Salesforce App Cloud. The Enterprise App plan costs $300/user/yr., while the App Bundle costs $960/user/yr. However, the free tier is available for every plan.

The Demerits of Heroku

High Costs:  The costs of using Heroku mounts up quickly after upgrading from the free plan.  Apart from the primary Heroku services, the add-ons are costly as well.

Relatively Small: Considering competitors such as Google and AWS, Heroku is a smaller PaaS provider.

Limited Flexibility: Developers that want to build a customized production environment would experience lots of limitations with Heroku.  For instance, libraries and services can only be installed through Heroku plugins.  So, it would be a challenge using a service that has no Heroku plugin. 

Slow Successive Deployments: The initial procedure for starting Heroku is quick and seamless. In fact, the first few successive deployments are also fast. However, the subsequent deployments of larger apps are sluggish. The dyno takes the app offline by restarting it before activating the update. So, a few seconds of the application runtime is lost.

The Alternatives to Heroku

Many companies that offer similar services as Heroku have emerged over the years.  We shall discuss the top 5 alternatives o Heroku. These companies are Back4app, Google app engine, elastic Beanstalk, Firebase, and Dokku on Digital Ocean.
