CircleCI is a widely used continuous integration and deployment tool that helps engineering teams streamline their application development workflows. By integrating tightly with GitHub, CircleCI allows for easy integration into pull request checks, ensuring that tests and linters are automatically run for every pull request and merge. Users have praised CircleCI for its reliability and responsiveness, noting that it has fewer problems compared to other CI tools they have used in the past. The support provided by CircleCI is also highly regarded, as the company continuously works on improving its product.
One of the key use cases of CircleCI is running tests on every commit to GitHub and deploying to development and production environments based on the branch. This allows engineering teams to ensure that bug-free code is shipped and accelerate the development process by automating the building, testing, and deployment of non-production environments. CircleCI also supports the automation of various build and test processes, including running pre-deploy and post-deploy scripts, executing test suites, and sending notifications through platforms like Slack.
Another important use case of CircleCI is its ability to handle the build process for different types of applications, such as Android, iOS, and web applications. By outsourcing the management of build servers to CircleCI, teams can focus more on developing custom applications while relying on a robust continuous integration and delivery solution. Moreover, CircleCI's concurrency feature allows users to split out test suites across multiple slices, significantly improving efficiency and reducing testing time. Additionally, CircleCI has been widely adopted for its cloud integration capabilities, allowing users to run automated tests in parallel containers.
In conclusion, CircleCI is extensively used by engineering teams for continuous integration and deployment pipelines across various software applications and environments. It simplifies the deployment process for Drupal and WordPress websites to platforms like Pantheon and provides a customizable environment for building, testing, and deploying workflows. With its tight integration with GitHub, responsive support team, and reliable performance reported by users from different industries, CircleCI is a popular choice for automating and optimizing the development process.

Continuous Integration for your software
Based on the cost for feature set that we needed we went with CircleCI. There were also more people on our team that knew how to use CircleCI already compared to other products which made it a preferred choice for ramp up. Other products were not as robust and quick to implement for what we needed at my company.

CircleCI Review
We use CircleCI when we need a good, independent CI/CD provider in an existing workflow. That said, we've begun investing more heavily in GitHub actions as it's closer to where our code is stored. CircleCI is a feature of a workflow, and can be filled by many different service providers; it's much more important to use one that fits well in your workflow than to choose one specifically before understanding the problem.

CI/CD for every developer and any organisation
CircleCI is a sass product which means you don't need to maintain your own servers. This can also be a negative as you are dependent on their service. This also means you can't ssh into a machine to see what went wrong like you can with Jenkins. However for most users this isn't needed and CircleCI's SLA is fine and there is a lot of community info on the internet to solve issues you might be having.

Circle CI the best on-cloud CI/CD system on cloud

Software engineering CI/CD pipelines done right!
CircleCI is still being developed and worked on continually while TravisCI is not.

Continuous Integration - Simpler.
CircleCI seemed to have a quicker setup than other similar products, with a good integration with GitHub repos. Projects are quick and easy to set up within the UI, and workflows can then be created off the back of those fairly intuitively. Clever interpretation of commit messages can also be used to skip jobs during setup when needed.

Help your developers build/test/deploy code quick!
Jenkins and Teamcity both have additional features that maybe you require, but they are also a lot more work to get set up and working. There's a much longer learning curve to getting these configured for a simple build. They're not hosted, so you have to maintain the infrastructure and scale yourself. They're both good products if you require more than CircleCI, but if not, skip the extra headache and go with something simple like CircleCI.

CircleCI - Solid Continuous Integration Tool
CircleCI does a lot of what we need it to do; however, I believe Jenkins is a better Continuous Integration tool. Jenkins has more capabilities and integrations. In addition, Jenkins is a much more widely used tool, which means more developers are familiar with it and have experience using it. This translates to quicker development and a faster/better ROI.

CircleCI is awesome
Not having to manage / deal with a Jenkins server is fantastic. I don't have much personally against Jenkins. I've set up and run a Jenkins server before. It's just complexity that doesn't really have much to do with the business beyond getting our software to our customers. My time is better spent on our core value, hence why having CI/CD as a service is such a great value.

A great CI/CD alternative
Since CircleCI gave us its infrastructure we don't have to worry about servers, provisioning and maintenance. Also CircleCI provides us great features to increase speed of builds by adding more containers to the build. Jenkins is the best open source alternative but it requires you to manage it.

Great CI Tool for Small Companies
Jenkins is usually self-hosted, Travis CI's infrastructure is largely unreliable (lots of tests time out for no discernable reason), and Semaphore encourages you to configure your CI/CD from a web UI. We like CircleCI because its hosted, our tests run largely as expected on their infrastructure, and we can configure it from a config file that we track in GitHub.

Frustrating UI but overall indispensable
It was our CTO who did the evaluation, not me, but as I recall other services weren't as parallelizable. We knew we wanted to run on many containers simultaneously for fast test results.
For us it really came down to CricleCI being the fastest and simples tool to get started with. The GitHub integration is slick and seamless and the scripting config file allowed us to configure our entire build system, including tests, in less than a day. It's very light weight and effective.
Circle was the first CI with simple setup, great documentation, and tight integration with GitHub. Using Jenkins was too much maintenance and overhead, TeamCity was limited in how we could customize it and run concurrent builds, TravisCI was not available for private repos when we switched.
Travis has full YML configuration in areas where CircleCI is slightly lacking still, which is great, but CircleCI offers more features, settings, and potential performance.
Codeship is simpler to use, you can use it entirely from their UI without modifying your Git repository at all. To some, this is important, existing Git repos need to be supported without adding files to them.
For others, and this is our situation, the opposite holds true--we'd rather keep our testing and deployment configuration along with our code in Git than managed somewhere separate. I believe this is a better approach in the long-term, especially when managing a large number of projects.
It also means most of our team members don't need to be in the CircleCI interface at all, possibly ever. They get added to the team, someone turns deployments on in CircleCI for the project, and then everyone can collaborate on making changes to the configuration, relying on Git's excellent merging abilities, rather than having multiple people potentially in the UI modifying configuration simultaneously, potentially reverting each others' changes.

One of the best CI tools available
Travis CI is great for open source projects – it's completely free, but CircleCI offers some support for closed projects as well. CircleCI has cheaper pricing plans, and you are able to customize them as much as you want. At Travis CI you can select only a predefined amount of concurrent jobs (2, 5, 10, etc.) while on CircleCI you can type your own number at a fixed price of $50 per container.

A fantastic CI solution for agile teams

CircleCI makes our deployments easy
- Travis CI and Scrutinizer
I had used Travis CI in some of my open source projects. However, it was too expensive for us so I looked for an alternative that was in our budget. Scrutinizer is also very useful, but also out of our budget. When we get larger I could see myself using Scrutinizer for quality tests, but I'd probably keep CircleCI for running unit tests and doing deployments.
January 12, 2017
Fast and Easy CI
I think these three tools are just as good as the other except that Travis CI supports mobile a lot better but price wise, CircleCI is the best that I have found and is supports the need for a startup. For a long while, CircleCI had Docker support before Codeship but now, Codeship has support for it as well.

CircleCI handled most of our Teamcity builds
We looked at various others, but the clincher for us was really iOS build support and CircleCi was one of the few that had it.
