CircleCI Software

Pros

CircleCI is very easy to use and is an excellent tool for general CI / CD. It integrates well with GitHub, runs your tests and gives you the ability to deploy when your tests succeed on a particular branch. CircleCI is great for any software development organization with a large or complex set of automated tests, especially with cloud services for most development processes. This is an excellent service with a good support and large community.

Cons

It would be nice to indicate different versions of PHP for testing and setting parameters for each. Thus, we can test our current production version, which must pass before deployment, and also test a new version of PHP, if we plan to go to it.

Pros

The best feature that CircleCI offers is the low set-up integration with GitHub allowing me to start using it in a few minutes.

Cons

I don't think there is anything in particular that I dislike about CircleCI, maybe the price could be a bit better?

Pros

The big plus is that this software works well with all the tools that modern developers use. The workflow script and the ability to run various test suites, or test types in one repository are fantastic. I like a lot of options to improve the configuration. Also great is that there is fast email support. Using CircleCI allows us to focus on our application development. It helps us to commit a simple config file to Git that controls the way that our software gets deployed.

Cons

What I like least about CircleCI is the slow learning curve for some programmers so that they can create the build and deployment script themselves. Lack of tools for really large projects.

Pros

At my mind, the main goal to which need to aspire every businessman is automatization of his business. To do that you need CircleCI. This tool helps me and my partner significantly normalize the development process and gave us more free time for our hobbies. The business problem that we solved with the software is the exact problem that I mentioned before. It is automatization, maybe I talk about it too much but it is justified. We tried to automatize our business by hiring some new employees but unfortunately, it was not as effective as CircleCI.

Cons

I don’t really like the idea of two versions of the software. In case of CircleCI, it is actually realized quite great and I can get used to it. But, this program exists to automatize the processes and make life easier and the fact of existing of two different versions is contradicted to this.

Pros

Each time CircleCI prepares your assembly for work, automatically compiles, automatically tests it. The excellent user interface, you always see only the necessary information. We started with the free version and now when our project started to generate profits we are going to buy the full version.

Cons

It would be nice to be able to support the assembly matrix as in Travis. We need this to compare the old and new build of our service.

Pros

With this wonderful program, we can increase productivity. The user interface and integration are very simple. Excellent price and free level. The simplicity of configuration is unrivaled. We use the platform for new projects on the first day. If something is unclear, the support service reacts very well, you can quickly contact them and discuss everything. This program is great for our continuous integration and delivery of our mobile applications. The platform is an important tool for improving the quality of our products. We use the program to perform all quality checks, create and deploy infrastructure around the world.

Cons

My biggest problem is that the platform is running slowly and clumsily from screen to screen. The versatility of the platform can be a bit overwhelming, and this sometimes affects usability: some settings are hard to find.

Pros

I love that this software is fast, very reliable and integrates perfectly with all the tools modern software developers use.

Cons

It can be a little slow for medium to big test suites, if you don't add enough parallelism (which comes at a price, of course).

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

Pros

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

Cons

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

Pros

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.

Cons

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

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

Pros

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 work with and I recommend you try one CI application. Even if its just for running code test automatically, or even it may make your developer start writing tests for their code.

Pros

Fully integrated with docker and because everything is moving to containers (or should be for scalability) this is huge for us. Tests can run automatically after pushing commits help identify problems before our clients would find them. The earlier you find a bug the cheaper its costs you in the end.

Pros

The UI and integration is easy and very straight forward. Were able to get builds going in a couple hours.

Cons

When picking a CI to use for our business we tried a lot of the big names and CircleCi was great except for the price point for how fast the builds were. Alternatives like Strider gave CircleCi a bad taste.

Pros

It offers very solid integrations with other services (such as Slack and GitHub) and it works well for managing an entire team's projects without getting too cluttered. Minimal interaction with user interface to get things done

Cons

It would also be great to be able to specify which docker images are cached on all executors.
it can take a couple of minutes just to deploy minor changes sometimes.

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.

Pros

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.

Cons

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.

Pros

Fast and resilient, especially when the release of version 2.0, we are able to benefit from docker layers caching..our build time improved by 70%.

Cons

sometimes it goes crazy especially in service discoveries since we are using docker compose to build and orchestrate ci env.

Pros

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.

Cons

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.

Pros

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

Cons

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

Pros

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.

Cons

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.

Pros

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.

Cons

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.

Pros

Awesome UI/UX. Excellent customer service support and ease of use. There is also a constant update on the product based on feedback which is not common with most products.

Cons

The developer community of Circle CI is not so strong compared to some other product. The have taken feedback on this and are already improving it.
