AppFog vs. Modulus vs. Shelly Cloud

AppFog provides the infrastructure web developers need to build apps without worrying about IT tasks or having to wait days to get servers ready for writing code. AppFog’s web application technologies include PHP, NodeJS, Ruby, Python, Java, .NET, MySQL, and PostgreSQL.

Modulus is a premier Node.js hosting platform that provides a complete technology stack for application developers. This includes custom SSL, WebSockets, MongoDB, statistics, and more.

Shelly Cloud is significantly cheaper than other PaaS hosting providers. You save money by getting all services needed to run your application from one provider. We run our own servers, so there is no "Amazon tax" included in our prices. You pay only for what you use with per-hour metered billing.
