Apollo vs Stackato: What are the differences?
Developers describe Apollo as "GraphQL server for Express, Connect, Hapi, Koa and more". Build a universal GraphQL API on top of your existing REST APIs, so you can ship new application features fast without waiting on backend changes. On the other hand, Stackato is detailed as "Enterprise ready private PaaS based on the Cloud Foundry open-source project and Docker". Stackato runs on top of your cloud infrastructure, and is the middleware from which your applications are launched. Developers simply upload their application source files to Stackato via IDE or command-line. Stackato automatically configures the required language runtimes, web frameworks, and data and messaging services.
Apollo and Stackato can be categorized as "Platform as a Service" tools.
Apollo is an open source tool with 7.53K GitHub stars and 935 GitHub forks. Here's a link to Apollo's open source repository on GitHub.
