Appveyor vs. Test Kitchen vs. Magnum CI

AppVeyor aims to give powerful Continuous Integration and Deployment tools to every .NET developer without the hassle of setting up and maintaining their own build server.

Test Kitchen has a static, declarative configuration in a .kitchen.yml file at the root of your project. It is designed to execute isolated code run in pristine environments ensuring that no prior state exists. A plugin architecture gives you the freedom to run your code on any cloud, virtualization, or bare metal resources and allows you to write acceptance criteria in whatever framework you desire.

Magnum CI is a hosted continuous integration service for private projects. It supports multiple languages and tools to run test suite. Service supports all major version control software and integrates with most popular code hosting platforms. There are no restrictions or limitations on where you store your source code, so even your own self-hosted repository will work right away.
