CircleCI supports Ruby, Python, Node, Java, PHP, and more, and are connected to MySQL, Mongo, Postgres, Cassandra, Riak, etc. Tests are run on a managed platform tuned for speed, can test many code pushes concurrently, and they split large test suites to run them in a fraction of the time, all automatically. CircleCI was founded in 2011 with the mission of giving every developer state of the art automated testing and continuous integration tools.
