An amazing product that revolutionized our testing and deployment processes!

Pros

CircleCI does everything we want in a CI product, and it works in the way that we want to use it (which is visiting the CircleCI user interface as little as possible). 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.

Cons

It can be slow. Especially if you don't have a lot of parallelism, but even sometimes if you do, it can take a couple of minutes just to deploy minor changes sometimes. This isn't much of a problem in reality, it just means you might need a different approach to your deployment process (one that doesn't require you to sit and wait for CircleCI to run before you move on).

Continuously improving over the years

Pros

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.

Cons

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.

Pricey, but a competitor in the continuous integration space.

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.

One of te best on cloud CI/CD for all kinds of application.

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.

Pros

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.

Cons

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

automated test do it right

Pros

- 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.

Cons

- 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.
