Pros
Pro GitHub & Bitbucket integration
Support for public and private GitHub and BitBucket repositories. It also has support for multi-user teams.
Pro Keeps it simple. Doesn't allow too many "tricky" things which means builds are generally very stable once they are up and going.
Pro Headless browser support
Alongside latest Chrome and Firefox, Codeship supports the use of Selenium, PhantomJS, CasperJS as well as tools like Capybara.
Pro Build status GIF
There's a continuously updated GIF of the build status of the repository allowing you to determine whether build was successful or not.
Pro Support for multiple tools, languages and databases
Support for e-mail, HipChat, Slack, Campfire, Flowdock, Grove, Webhook, Github Status API.
Support for Ruby, Python, Node, Dart, PHP, Java, Scala, Groovy, Clojure, Go.
Support for: PostgreSQL, MySQL, MongoDB, Redis, Memcached, ElasticSearch, SQLite.
Pro Supports 7 cloud providers
Support for AWS, Digital Ocean, Rackspace, Google Compute, Joyent, Softlayer, Openstack.
Pro Docker support
Pro Simple deployments with a choice of 5 deployment tools
Support for Capistrano, Fabric, Chef, Puppet, Ansible and allows for writing your own scripts to deploy and manage your infrastructure.
Pro Supports 10 hosting providers
Support for Heroku, Engine Yard, Nodejitsu, dotCloud, App Engine, AppFog, Modulus, Openshift, Cloud Foundry, Fortrabbit and you can also run your own script to deploy anywhere.
Pro FTP, SFTP, SCP, RSYNC and SSH support
You can use FTP, SFTP, SCP, RSYNC and SSH for Continuous Deployment.
Pro Code Climate & Coveralls support
Automated code review for RoR and JavaScript and test coverage history and statistics with Code Climate and Coveralls.
Pro Local iteration
Debugging on remote build agents is a nightmare (especially without isolated builds). Concourse CI can be run locally. When there are problems with the pipeline definition, it can be run and debugged locally. That means it takes less time to find and fix problems.
Pro Flexible
Resources are to Concourse as plugins are to Jenkins. In other words, resources allow Concourse CI to do just about any work necessary in a build. But resources follow a "service provider interface" that makes them easy to build in any language (not just JVM languages) and have a clearly defined computing model, built for composition. Resources don't clutter UI or tax performance.
Pro Scalable, reproducible deployment
BOSH is an open source tool for release engineering, deployment, lifecycle management, and monitoring of distributed systems. Since Concourse CI is built on top of BOSH, Concourse can scale across many servers or be run in the Cloud.
Pro Isolated builds
Build isolation keeps workers "clean". There's no configuration drift of agents. Or flaky interactions between build jobs.
Pro Usable
Visual pipeline view makes it clear what the automation does. Simple navigation to logs makes it easy to understand what happened in a build.
Pro Simple
Concourse defines three primitives that, together, can express arbitrary features and pipelines.
Cons
Con Doesn't support git modules
If repo contain private submodule - build will fail, no way to add your private key.
Con Any time you ask support for help on Codeship basic (which isn't free anyway), they will just try to up sell you to Pro version.
Con No Global variables that can be shared amongst all projects.
Con Environment variables are exposed. Any keys or secrets can just be copied.
No option to mask them unless you reduce permissions for those users. Developers need to be able to modify a job but probably shouldn't be able to copy a production api key. Just needs one more level of permissions here.
Con Too many permissions on Bitbucket
When registering with Bitbucket Codeship it requests way to many permissions, even "Read and write to your team's projects and move repositories between them". Before giving all these permissions you have to be sure you can trust this service.
Con Limited infrastructure options
The downside of building on BOSH is that a full, scalable deployment of Concourse CI requires AWS, vSphere, or OpenStack. If you don't already have these, any one of them can be a big effort to set up, just to get a build server running. Might not be a good fit for smaller teams.
