Heroku vs WP Engine

• Heroku operates on a platform-as-a-service model with a pricing range of $0.10/mo to $750.00/mo, providing effectively unlimited bandwidth and disk storage for arbitrary application code, whereas WP Engine anchors its costs between $30.00/mo and $276.00/mo for WordPress-specific hosting.
• WP Engine enforces strict caps on disk space, ranging from 10 GB to 50 GB, with storage overages billed at $0.20/GB.
• Bandwidth on WP Engine is constrained between 75 GB and 500 GB, with extra egress costing $0.05/GB, a sharp contrast to Heroku’s unmetered policy.
• Heroku scales RAM from 0.05 GB to 800 GB per instance, while WP Engine manages infrastructure behind the scenes, limiting the user to a set visit count between 25,000 and 400,000 per month.

Heroku functions as a general-purpose runtime environment. It is designed for developers who need to deploy Node.js, Python, or Go binaries on top of underlying cloud providers like AWS, without caring about the specific hardware, such as the EPYC processors commonly found in modern data centers. Because Heroku offers unlimited bandwidth and disk, the cost remains predictable even if your application generates high volumes of log data or static asset traffic. It abstracts away the need to manage file system sizes, which avoids the nickel-and-diming associated with disk overages.

WP Engine is built specifically for the WordPress ecosystem and carries the operational overhead of a managed CMS environment. If you are hosting a high-traffic site with large media assets, the $0.20/GB storage overage fee can quickly inflate your monthly spend compared to Heroku’s flat structure. WP Engine provides value through site-specific caching and security layers, but it forces a rigid resource ceiling that does not exist on Heroku’s more flexible, container-centric platform. Choosing between them depends on whether you require a specialized content management environment or raw control over a custom-coded application stack.
