Travis CI vs TeamCity comparison of Continuous Integration servers

	Travis CI https://travis-ci.org	TeamCity https://www.jetbrains.com/teamcity/
Unique feature	Build Matrix, ease of use, GitHub integration	Technology awareness
Type of product	SaaS, Self-hosted / On Premise	On Premise
Offers a free plan	Yes Free for open source projects	Yes They offer a great free professional plan, limited to 100 build configurations and 3 build agents. From there, you pay for each aditional agent you want (discounts if you purchase more than 1 agent at a time). They also provide a free plan for open source, non commercial projects, and steep 50% discounts for startups.
Predictable pricing	Yes Clearly defined monthly plans, depending on concurrent jobs needed.	Yes They have a clear list of prices per number of agents.
Support / SLA	Yes Available via email, or dedicated online interface for paid plans.	Yes
Paralellism Every CI servers tends to address this differently (parallel, distributed, build matrix). Some of it is just marketing, and some is just nuance. For this table, parallel means that tasks can be run concurrently on the same machine, distributed means that tasks can be scaled horizontally, on multiple machines How to split tests in parallel in the optimal way with Knapsack Pro	Yes TravisCI makes it very easy to split your build into different stages which are then run in parallel (ie: run integration tests separate from the unit tests). TravisCI calls this a build matrix: https://docs.travis-ci.com/user/build-matrix/. You can also very easily split tests accross several VMs using the knapsack_pro gem.	Yes
Distributed builds distributed means that tasks can be scaled horizontally, on multiple machines How to split tests in parallel in the optimal way with Knapsack Pro	N/A	N/A No specific mention that we could find, but judging by the wording used it would appear that tasks can be divided accross different machines.
Containers support / Build environment	Yes TravisCI runs each build in a isolated virtual machine. Pre-build packages include a few which support specific languages (Ruby and JavaScript included) or other software (Git, various databases), but vanilla packages such as Ubuntu Trusty are also available.	Yes First class Docker support, among others
Analytics / Status overview Analytics and overview referrs to the ability to, at a glance, see what's breaking (be it a certain task, or the build for a specific project)	Yes Available by default in Travis (this is what most of the web UI consists of)	Yes Great system overview, even allows building your own dashboards in order to see everything you're interested in at a glance.
Management support How easy is it to manage users / projects / assign roles and permissions and so on	N/A	Yes Allows assigning roles, LDAP and Windows domain integrations and more.
Self-hosted option	Yes	Yes
Hosted plans / SaaS	Yes	No
Build pipelines A continuous delivery pipeline is a description of the process that the software goes through from a new code commit, through testing and other statical analysis steps all the way to the end-users of the product.	No Specifically built around GitHub pull requests. Pipelines can be defined, but parts of the process need to be implemented separatelly in GitHub.	Yes Unlike most options in the CI/CD space, TeamCity allows defining pipelines using a Kotlin-based DSL. This unlocks a lot of potential, such as templates for common CI/CD tasks, and deep integration with various IDEs (not just JetBrains IDEs)
Reports Reports are about the abilty to see specific reports (like code coverage or custom ones), but not necesarily tied in into a larger dashboard.	Yes (partial) No persistent storage eliminates the possibility of code coverage reports on TravisCI alone. There is support for integrated 3rd parties such as Coveralls for reporting code coverage.	Yes Something that stands out from the rest, allows integrating third party reports, as long as they produce HTML output.
Ecosystem Besides the official documentation and software, is there a large community using this product? Are there any community-driven tools / plugins that you can use?	No plugin support in TravisCI, plugins for other tools	Yes JetBrains has a rich ecosystem of plugins in general.
Specific language support: Ruby Some CI servers have built-in support for parsing RSpec or Istanbul output for example and we mention those. Some others make it even easier by detecting Gemfiles or package.json and automate parts of the process for the developer.	Yes TravisCI is designed to be a simple way to integrate CI/CD in your workflow so it has a couple of features aimed at specific languages, such as Ruby, starting from pre-built containers (with RVM already installed, for example) all the way to automatically running specific platform commands (such as detecting a Gemfile in the root of the project and automatically bundling dependencies). TravisCI also builds a Ruby SDK for easier use of the API.	Yes Using what they call 'Technology Awareness', promises great intehration with Ruby projects, with features such as testing framework support, static analysis and code coverage available out of the box, with no additional work required: https://www.jetbrains.com/teamcity/features/technology_awareness.html
Specific language support: JavaScript	Yes TravisCI is designed to be a simple way to integrate CI/CD in your workflow so it has a couple of features aimed at specific languages, such as Javascript, starting from pre-built containers (with node already installed, for example) all the way to automatically running specific platform commands (such as detecting a package.json in the root of the project and running npm test)	No (partial) Unlike Ruby, there's no first class support for Javascript, although they do advertise the fact that their large collections of plugins can cover any use case for Javascript projects: https://plugins.jetbrains.com/teamcity
Integrations 1st party support for common tools (like Slack notifications, various VCS platforms, etc)	Yes By default, TravisCI is built to work with GitHub. Additionally, there is strong support for 3rd party tools like Coveralls, BrowserStack, etc.	Yes Great cloud integrations (Google Cloud, AWS, VMWare, etc) as well as 'key' integrations (VSCode, Jira, even NuGet)
API Custom integreation is available, via an API or otherwise, it's mentioned separately as it allows further customization than any of the Ecosystem/Integration options	Yes Offers a feature-rich API that allows both reading data, as well as triggering or cancelling builds.	Yes Unlike most tools, which offer just a Rest API, TeamCity provides ample opportunity for extension via plugins, their own API, and service messages (formatted messages on stdout)
Auditing	N/A	Yes
Additional notes		Great ecosystem, with a strong focus on integration with other tools (not only JetBrains).
