Pros
Pro Free for open-source projects
AppVeyor is free for public GitHub repositories.
Pro Supports Windows build enviroment
AppVeyor has a build environment for Windows available.
Pro Clear, straight-forward user interface
Well I suggest you check it out for yourself, but what I like most is that it's simple yet effective: no bells and whistles, simple black/grey/light-blue/white color scheme, it's immediately clear where you have to go for each specific task, and build settings pages are like that as well. Getting a 'standard' build running literally took me a minute the first time I used it.
Pro Easy access to build VM
AppVeyor allows the user to login to the actual build VM.
Pro The initial setup is easy
There's practically no setup involved prior to working with AppVeyor: simply sign in, add the project, and start a new build.
Pro Run environment locally or in the cloud
Simple and convenient.
Pro Monitoring option
You can monitor the status of your environments and servers in one control panel. You can also receive notifications when the status of an env or a server changes.
Pro Convenient environment editor
A user-friendly interface where you can edit your environments. All the changes will be applied on-the-fly.
Pro Cost-effective
You can use your own cloud servers and don't pay for PaaS equipment.
Cons
Con Not free
This is open-source but not free.
Con Configuration is limited
AppVeyor's configuration (which is done from the .yaml file in the root of the project) is unfortunately very limited. The configuration is either tied to a branch or, in other cases, it's global. This limits the developer to a single build process.
However, since you can use arbitrary scripts for building, all those limitations can be overcome. Configuration can also be done from the web UI without a .yaml file.
