Pros
Pro Free for open source
Coveralls offers unlimited free support for open source projects.
Pro Maturity
Coveralls is older than Code Climate and already supports 21 languages. It also seems like it's the most popular given how new some of the other services are, which is great for support.
Pro Your own server, your intellectual property
You don't trust a third party service to host your IP? Host your own server, at no cost (every cloud provider will host your server freely for the first year).
Pro Open source
Pro Distributed references
The code coverage "references" are the previous measurements of code coverage. These references are distributed: all the team members can share the references in the same way they share the source code.
Cons
Con Terrible support
Con The user interface is hard to understand
Con It's defective and integration doesn't work properly
Con Poor tooling
Depending on your language the tooling is practically abandonware.
Con No support for common coverage report stadards
They accept their own format over their own HTTP API. Other services allow the uploading of standard reporting formats and parse them internally.
Con Not really user friendly
There is little/no graphical user interface. Everything is done via command line instructions.
