Flywheel vs Heroku

Flywheel and Heroku serve fundamentally different segments of the infrastructure market. Flywheel operates as a specialized platform for WordPress, with pricing ranging from $15.00/mo to $290.00/mo. It bundles resources like 5 GB to 50 GB of disk space and 20 GB to 500 GB of egress, strictly calibrated for site traffic rather than raw compute. Heroku, by contrast, functions as a general-purpose PaaS, offering a wider entry point at $0.10/mo for small dynos, scaling up to $750.00/mo for high-memory configurations. While Flywheel limits users to 30 app instances, Heroku focuses on vertical scaling, providing up to 800 GB of RAM for complex, memory-hungry applications.

• Flywheel imposes a $0.20/GB penalty for storage overages and a $0.05/GB fee for excess egress, reflecting their narrow focus on site delivery.
• Heroku provides essentially unlimited disk storage and bandwidth, which simplifies cost forecasting for data-heavy applications compared to Flywheel's tiered caps.
• Memory allocation on Heroku is granular, starting at a negligible 0.0488 GB, whereas Flywheel abstracts memory entirely behind their specific site-tiering model.
• Heroku utilizes shared underlying hardware similar to standard AWS EC2 instances, while Flywheel maintains a proprietary environment optimized specifically for the PHP/MySQL stack.

Choosing between these two depends on your stack requirements. Flywheel removes the burden of server maintenance for WordPress sites, provided your traffic patterns align with their monthly visit caps. Heroku offers superior flexibility for custom codebases that require persistent memory and unlimited data transfer, though you remain responsible for managing your own application scaling as your user base expands. If your project runs on standard web tech and demands unmetered egress, Heroku avoids the surprise overage fees inherent in Flywheel’s usage-based model.
