Overview

About CircleCI

CircleCI helps users automate the software development process using continuous integration and delivery. The tool builds software using custom job orchestration with workflows. CircleCI can be configured to deploy code to various environments including AWS CodeDeploy, AWS EC2 Container Service (ECS), AWS S3, Google Container Engine (GKE) and Heroku. Other cloud service deployments are scripted using SSH or by installing the API client. CircleCI supports languages that are built on Linux, C++, Javascript, .NET, PHP, Python and Ruby. Users can speed up the app-building process with expanded caching options including images, source codes, dependencies and custom caches. Automated provisioning allows parallel execution of programs resulting in less downtime waiting for a workflow to complete. CircleCI dashboard enables users to see all their builds on a single screen. It integrates with third party applications such as Slack, HipChat, Campfire, Flowdock and IRC. Pricing is per month. Support is provided via online forum and email.

Battle tested and well documented

Satisfied ;)

What they liked
  • One of the market leaders
  • You can bet it is going to be here for at least next few years and your one off implementation and deployment of this service will do for long time without ay significant change and it will serve you reliably
Room for improvement
  • For some not_totaly_standartd deployments or integrations it is (as many similar products) a bit tricky
  • But thanks to the huge community you can find some solution for pretty much everything quite quickly

Continuously improving over the years

Verified reviewer

What they liked
  • Responsive support, much faster builds now I can easily parallelize things with Workflows 2
  • 0
  • Very easily integrated with GitHub and other code-quality services
  • Able to build in macOS if necessary
Room for improvement
  • I would like the ability to specify resources available to a machine, fine to charge more for this feature
  • I would like to use Workflows 2
  • 0 with macOS builds
  • It would also be great to be able to specify which docker images are cached on all executors, fine to charge more for this feature

Does the job, but lacking in features

Verified reviewer

What they liked
  • It's relatively simple to get started
  • I like that you can pick between Docker and VMs
  • It integrates with GitHub nicely
Room for improvement
  • The Docker in Docker paradigm doesn't work for us since we use containers
  • We end up using VMs anyways
  • I think the configuration language is not that great to use and can quickly get unwieldy for larger CI workflows (especially when repeating jobs with different parameters)
  • There are also outages at least once a quarter

automated test do it right

Verified reviewer

What they liked
  • - Is integrated with several tools like slack - Configure a project is simple and quick, and most of the cases once you have done this, you will not need to log in into the platform
  • You will have build going in a couple of hours
  • - I have it running in several project and works really well
Room for improvement

- Pricing could be a little bit better I guess or have a better free plan for beginners, I don't think any cons of using CircleCI actually

Great build/deploy tool

It's quick, easy to set up, and I like it. There are some usability fixes that are needed around user maangement, but otherwise, it's great! And works with all of the languages I use out of the box, and with no configuration.

What they liked
  • CircleCI was great and easy to set up
  • It allows me to see what's going on with all of my builds quickly and in real time
Room for improvement
  • The user management is not very good
  • I have 5 contributors to a repo, and I can only add two of them as users
  • I can't even add users that aren't a contributor to the repo
  • My boss, my QA people, and my PMs can't see anything that's happening in the platform

CI/CD with few lines

Integration with IOs allow us to build and test the mobile apps and automatize our whole CI/CD pipeline

What they liked
  • Sine the release of circleci v2
  • 0 using containers as the main advantage using circle has become much simpler and powerfull
  • Their integration with IOs its a powerup in front of other CI/CD platforms
Room for improvement
  • The ui really needs to cleanup a bit, make it simpler
  • Also their need to provide more integrations with third party tools

I love CI about as much as Circle does

Verified reviewer

What they liked
  • The simplicity of configuration is unparalleled
  • We use CI on new projects day one
  • The ease of use, and setup, is definitely what keeps us coming back
Room for improvement
  • Lack of tools for multi project repos
  • We would love to keep our front and back-end code together in one repo while splitting the CI for them
  • So, it'd be great if we could run two builds separately based on the same repo

CircleCi has changed how we develop

Overall I've been really happy with the performance from circleci. Even their free plan has been great.

What they liked
  • Has helped up to totally streamline our development and testing workflow
  • Each service has it's own pipeline
  • The management interface and docker integration have made the setup and monitoring process super simple

Easy to use and powerful

Verified reviewer

What they liked
  • Super easy configuration and initial setup
  • Powerful features like running steps of build/testing process in parallel
  • CircleCI is our teams core safety net for catching bugs and deploying safely, often
Room for improvement
  • Not a lot to dislike
  • Sometimes the interface changes and buttons that you used to expect to be there (like the one for rebuild with out cache) disappear
  • Hopefully there will be fewer of these unexpected changes as 2
  • 0 becomes more mature

Powerful CI / CD platform

Verified reviewer

What they liked
  • Great UI, easy to setup, easy to manage
  • All integrations "just work", we use Slack notifications, webhooks for triggering build, and even those sweet browser notifications when we need to make sure that the build is successful
  • Impressive Docker support
Room for improvement
  • Circle 2
  • 0 offers improved customizability, added more features, but for small and simple projects it's not as easy to setup anymore
