Atlantis vs Shelly Cloud: What are the differences?
Developers describe Atlantis as "Open Source PaaS Built on Docker, by Ooyala". Atlantis is an Open Source PaaS for HTTP applications built on Docker and written in Go. It makes it easy to build and deploy applications in a safe, repeatable fashion, and flexibly route requests to the appropriate containers. On the other hand, Shelly Cloud is detailed as "Platform for hosting your Ruby and Rails apps (hosted in Europe)". 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.
Atlantis and Shelly Cloud belong to "Platform as a Service" category of the tech stack.
Atlantis is an open source tool with 381 GitHub stars and 33 GitHub forks. Here's a link to Atlantis's open source repository on GitHub.
