Pros
Pro Quick setup
CircleCI excels with its setup process. All that's needed is a GitHub login and CircleCI automatically detects the settings for Ruby, Python, Node.js, Java and Clojure. The setup process is their most widely praised feature.
Pro Simple and intuitive GitHub integration
CircleCI can be connected to any project that is hosted on GitHub by logging in using the GitHub OAuth and adding the desired repository.
Whenever a new commit is pushed to GitHub, CircleCI runs the tests that have been already defined and if none of them fails, the build is deployed to the runtime environment.
Pro SSH support
Users can access the Virtual Machine via SSH and run commands.
Pro Easy configuration with YAML
In most cases CircleCI automatically get settings from your code. When it fails, edit circle.yml.
Pro Very fast parallel testing
Tests can be parallelized across multiple machines reducing test times drastically. They support up to 8-way parallelization. Additionally, CircleCI caches the build environment.
Pro Clean, intuitive UI
Circle CI's web UI is clean and easy to use.
It gives all the information for a single build in a feed and gives the explanation for each step of the build, what it's doing and what the step is related to. On the top it displays author information and the time and date when the build was started and finished.
This is all done by giving only the most essential information without clogging the screen.
Pro Supports 8 languages and 16 databases
Support for Ruby, Python, Node, Java, PHP, RoR, DJ, JavaScript. It also detects settings for Ruby, Python, Node.js, Java and Clojure.
It als has support for: MySQL, MongoDB, PostgreSQL, Cassandra, Riak, Redis, SQLite, Solr, CouchDB, ElasticSearch, Neo4j, Couchbase, Lucene, Sphinx, ThriftDB, Memcache.
Pro Headless browser support
Alongside latest Chrome, Firefox and Webkit (installed using xvfb), CircleCi supports the use of Selenium, PhantomJS as well as tools like Capybara and Cucumber.
Pro Support for Queues
Support for RabbitMQ, Beanstalk and Resque through Redis.
Pro Supports Docker
CircleCI can continuously deliver Docker images to hosts that support Docker containers.
Pro Provides time taken for each step
Eg:
./1.setup.sh 48s
./2.build.sh 56s
With this information, it's easy to find out which line of the script is the bottleneck of the build process.
Pro Comprehensive cache dependencies
Can specify the cache dependencies on
- checksum "package.json"
- Branch
- BuildNum
- Revision
- Environment.variableName

Pro Intelligent notifications
CircleCI can notify via email, Hipchat, Campfire and more. And it does so only when necessary.
Pro Can test many code pushes concurrently
You can push multiple batches of code concurrently.
Pro Supports 10 Continuous Deployment solutions
Support for Heroku, AWS, Engine Yard, dotCloud, Fabric, Nodejitsu, AppFog, Capistrano, Rockspace, Joynet.
Integration with Heroku is solid with the ability to automatically deploy or merge branches.
CircleCI is also very flexible with the deployment arrangement allowing SSH key management, deployment freedom including directly to a PaaS, using Capistrano, Fabric, arbitrary bash commands, or by auto-merging to another branch, or packaging code up to S3.
Pro Can deploy to any server, on any platform
Distelli suports all of the popular platforms and can be deployed to any server.
Pro Allows tracking deployments
Through Distelli, the user can track who deployed what application to what environment, as well as when it happened.
Pro Environment-specific commands
In Distelli, the user can set up environment-specific commands to run before, during, or after a deployment.
Pro Displays real-time logs
As the user deploys, real-time logs are displayed, providing useful information and giving the user an intuitive means off which he/she can operate.
Cons
Con Changes the environment without warning
Unless you count forum posts as a warning. A mysql upgrade caused days of debugging.
Con Does not cache docker images
The way to fake it is to save the image on disk, in the cache folder (it tars it), and restore it afterwards. But in tests it was slower than not caching.
Con Docker is way outdated on the VM provided
Currently (October 5th 2016), Docker installed on the VM is: 1.9.1-circleci-cp-workaround, build 517b158, and docker-compose is 1.5.2, build 7240ff3. docker-compose in particular is almost too old to be used.
Con Security concerns
Although Distelli is very easy to use and helps developers who don't want to spend time setting up their build environment, there are a number of security concerns regarding the tool. This is because you have to host an agent that allows RPC with a relatively unknown third party.
