Is Heroku a Web Server?


When it comes to deploying web applications, there are various options available. One popular choice is Heroku.

But what exactly is Heroku? Is it a web server? In this article, we will explore the nature of Heroku and understand how it fits into the web server landscape.

Understanding Heroku:

In simple terms, Heroku is not a web server but rather a cloud platform as a service (PaaS). It provides developers with an easy way to deploy, manage, and scale their applications. Instead of worrying about infrastructure and server management, developers can focus on building and deploying their code.

Benefits of Using Heroku:

  • Simplicity: Heroku simplifies the deployment process by abstracting away the complexities of server configuration. With just a few commands, developers can deploy their applications to the cloud.
  • Scalability: Heroku provides built-in scalability features.

    It allows applications to handle increased traffic by automatically provisioning additional resources when needed.

  • Add-ons: Heroku offers a wide range of add-ons that can enhance your application’s functionality. These add-ons include databases, monitoring tools, caching systems, and more.

The Role of Web Servers in Heroku:

In the context of Heroku, web servers play a crucial role in serving your application to users. While Heroku itself is not a web server, it leverages popular web servers like Apache or NGINX to handle incoming requests and route them to your application’s dynos.


Dynos are lightweight containers that run your application code on Heroku. Each dyno runs a specific process or command and can handle a certain amount of traffic. Heroku allows you to scale the number of dynos based on your application’s needs.

Deploying an Application on Heroku:

Here are the general steps to deploy an application on Heroku:

  1. Create a Heroku account and install the Heroku CLI.
  2. Navigate to your application’s directory using the command line.
  3. Initialize a new Git repository.
  4. Create a new Heroku app using the CLI.
  5. Configure any necessary environment variables.
  6. Push your code to the Heroku remote repository.
  7. Scale your dynos as needed to handle traffic.


In summary, while Heroku is not a web server itself, it provides a convenient way for developers to deploy and manage their applications in the cloud. By leveraging popular web servers, Heroku ensures that your application is served efficiently and can scale seamlessly. So if you’re looking for an easy-to-use platform to deploy your web applications, give Heroku a try!
