When compared to non k8s-based PaaS solutions like Heroku, using a managed k8s offering like EKS can be expensive. For those who are running small scale projects, k8s is an overkill and the benefits of scalability and stability might not be enough to justify using Porter.
However, the underlying EC2 machines added to the $72/mo management fee on EKS is relatively cheap, and we've found that if you are using more than 4GB RAM/4 CPU on Heroku, the cost on EKS starts getting cheaper than Heroku (at scale, using EKS is substantially cheaper than Heroku). That said, we are actively working on partnering with independent cloud providers with cheaper k8s offering for those who are running small projects. At the moment the cheapest option is to use Digital Ocean with Porter, which can be as cheap as $35/mo. With regards to Qovery, AFAIK, Qovery also runs EKS and does not yet have the option to use cheaper cloud providers like Digital Ocean.
