CircleCI Reviews

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.

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.

CircleCI is highly configurable for many different types of workflows. We rely on CircleCI for continuous deployment. Our tests automatically run and deploy code to the correct environment depending on the branch it's pushed to. It's also generally reliable these days. Reliability was an issue for us a few years ago but those issues are mostly gone now.

Since CircleCI is highly configurable it can also be difficult to build out a custom flow that works the way you need it to. We spent more time than we wanted to getting our automated deployment system set up.

These features helped us with fixing issues and shipping more: Configuration Management, Build Log and Approval Workflow.
All of that made our workplace headache-free and reduce the number of sleepless nights for our developers...

The software lacks these features: Chat/Messaging, Authentication and Assignment Management.

It's powerful, it's got lots of features, and the customization is limitless. CircleCI improves the developer experience many times over. It's also fairly reliable, and makes handling a large project simpler.

It can go down sometimes, debugging can be a bit hard and cryptic. Support is also fairly lackluster.

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.

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.

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.

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.

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.

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.

Circle 2.0 offers improved customizability, added more features, but for small and simple projects it's not as easy to setup anymore.

Circle CI is being trusted by FB for React, and Fastlane. So if it works for them I think that is a great testament to it.

Doesn't allow as many languages and environments out of the box as Travis CI does.

Realy fast, and requires almost none configuration to get going, I didn't know much about it at the start, but then o learned a lot very fast.

People do not get its importance at first, it's a real pain to make them understand why should them to spend time on this sort of thing.

It is incredibly easy to get started, you can be integrated in hours and from then on its a consistent reliable platform for all your CI needs.

As test suites grow and parallelization becomes important it can get awfully expensive. I still use it on every project but I was at a prior company where we racked up bills in the thousands a month without really trying for not that big a product. This was definitely due to some poor planning but CircleCI makes it easy to land yourself in that kind of situation if you're not careful.

The great configurational freedom to the user makes it suitable for any and all kinds of applications. The step by step view provided is very helpful UI to track the whole process. The YML templates make it very easy to set up and the git configuration part is very well documented and just a few steps can make it work.

The pricing of the tool is a bit on the higher side compared to its competitors. Docker support is not complete.

I am using CircleCI within many projects and I like it - its feature-rich, supports every usecase we need and from my perspective is absolutely sufficient as CI/CD tool for projects I was working on. It also has free plan which could be enough for smaller teams or projects.

Not very often, but still, sometimes an inexplicable black magic happens and it requires a bit of debugging and reconfiguring of the project or the CircleCI.

Easy to configure via a YAML file
Sends email notifications without the use of external services
Not only runs our tests, but also triggers our deployments

Proactive communication about updates and breaking changes
Questions to account rep can sometimes take too long (for us -- > 1 day) to respond

I like how easy it is to see failed tests and to re-run the test suite, if needed.

I don't have any problems using CircleCI -- sometimes the test suites take a long time to run, but I think that has more to do with how robust our test suite is than anything to do with CircleCI.

automated testing, building and deploying really helped or project in reaching maximum velocity for the scrum teams

What I least like about Circle CI is the slow learning curve for some of the programmers so that they are able to make a build and deploy script themselves

generous free plans for open source projects
easy to set up
plenty of features
plenty of customization
runs quick

Additional containers are a bit pricey. There are other services offering similar products at much lower prices.

It provides many useful features, and I can use most of them with a free plan.
Customer service is also excellent.

'Workflows' is useful, but it can not be tested locally by its nature.

The software works great, is fast, and extremely easy to use.

None, but I believe paid options could be less expensive

Love this software we use it for automated unit test checks before deploying and it works great!

Honestly, I don't have anything in particular that I disliked, you guys have a great product

This is my first experience using a CI software tool, and it's AMAZING. Tools that automate the workflow of code deployment gives a lot of

Not too much of a problem, but there's somewhat of a learning curve to set up your environment. Took me a few days to educate myself in the specifics, such as caching, jobs, workers etc.

Easy to start, good integration with GitHub, free for small and open-source projects.

The pricing is a bit higher compared to its competitors.

CircleCI is a easy to use solution for building and deploying your projects. It support concurrency and has unlimited build time in most plans

If you need to build on MacOS, you'll need to pay a high price and get limited build time. This makes the solution less desirable than its competitors.

Multi-architecture builds, full Docker support, and streamlined declarative pipeline config made me feel right at home!

Could use a better comparative analysis marketing doc to explain differences from folks coming from Travis-CI to better understand the advantages.

- Integration with GitHub and Slack
- Automation of several types of tests (schema validation, integration, unit tests, etc)
- Easy to monitor the results of tests while they're still running

Perhaps due to the high volume of simultaneous users, sometimes it would be faster to run tests locally rather than on circleci
