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.

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.

We used this CI/CD management software to deliver the products as fast as we can to test the water (product-market fit, validation...), then iterate, and pivoting quickly if needed. It's a good tool to do all of that.

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.

We deploy in the form of a circle. Since it was already in place when I began working here, I can't speak to how things were before, but I can say that it makes things much simpler for newcomers to the organization.

Excellent customer service, and now even faster builds Workflows 2.0 makes it simple for me to parallelize tasks. Simple integration with code-quality services like GitHub. If necessary, it can be built on macOS.

Nothing of significance to point out. It's a little messy with reduced resolutions if we go to a project and filter it by Branch Name. On a mobile device or a browser tab, for example. Except for that, everything else is fine.

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

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

The ui really needs to cleanup a bit, make it simpler. Also their need to provide more integrations with third party tools

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.

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

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.

It is easy to setup. It can do very fast parallel testing. I find UI of it clear and easy to use. it provide integration of many app like GitHub. it supports 8 languages and 16 databases and it also supports Headless browser.

it Does not cache docker images. Docker is way outdated on the VM provided. Other than that i don't find any problem with it. I think it is best

As any Continuous Integration tool it does what it should do. Builds and runs. Hard to say what's the most because haven't used other CI tools but CircleCI does what's expected and there was no thoughts about changing to other tools. So I would recommend using it.

The tutorials are not yet clear. They don't lead from start to workable CI.

My go-to on every SAAS product. Delivers the goods everytime.

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.

Used it with a number of applications, the GIT integration was very smooth. It is used for the deployment of the master on test and production environment by simple pull request creation and branch merge.

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.

It automates many repetitive tasks such as running the tests, building and deployment to various environments and it makes my life easier.

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.

It's inexpensiveness is the main attraction but also along with that CircleCi provides tons of other helpful features as well you can share the test logs via email as well.

As for my use case I don't have anything to dislike and it is ideal for me.

It helps me to analyze all build quickly in real time. It is pretty simple to configure, setup and use. It has a pretty good integration with various remote repositories and it can run tests and give you results.

The learning curve is steep for some developers. It has two versions of the software, which sometimes makes it difficult to manage.

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.

I'm developing and managing various web services and mobile apps in a small startup. CircleCI is essential for productivity and maintaining code quality with my team.

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

CircleCI brings a lot of security to our code deployment workflow: running unit and integration tests, and code analysis such as linters, it's a godsent.

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.

In general works and do it's job in small, experimental projects.

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

The pricing is a bit higher compared to its competitors.

Circle CI is a very nice CI tools, especially if you need to build on Apple devices

It's a bit pricy regarding other service that can be opensource

It's an excellent unobtrusive CI that keeps developers writing software rather than waiting for tests to finish. It can quickly run through thousands of tests and send alerts once complete. The UI is great and easy to use.

The config is probably the worst of the cloud CI software.

I code for a number of repositories that are integrated with CircleCI to run several integration, schema and unit tests. I have never had to configure it, and I imagine that the work required to do so is non-negligible. However, after that, it's very easy to use and automate a very boring, yet very important part our processes.

- 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
