Integrations are great. Configuration was easy and has a solid number of features. We use this in our CI for a handful of apps and it's very easy to use. Review collected by and hosted on G2.com.

Wish it had better integrations for mobile apps (android / iOS) alternatives have easy integrations into those developer platforms to pull certificates etc. Review collected by and hosted on G2.com.

what i like the best about CicleCI is its speed and flexibility, and automation of testing and user friendly interface. and easy to implement and its easy to approach the customer support Review collected by and hosted on G2.com.

i think one of the downsideof circleCI is the complex of configuration for newbie or begginners, especially with advance feature Review collected by and hosted on G2.com.

The Continious integration server is operating mainly online through Single sign on to Github or E-mail authentication. I shall confess that the integration server is fast. It was built to speed up releases. Besides, all those features, their cloud plans enpower their solution. Review collected by and hosted on G2.com.

I hope their customer support team will focus on customer success and satisfaction to include the customer feedback in their upcoming horizons. Review collected by and hosted on G2.com.

Ease of use, ease of implementation, nothing else! Review collected by and hosted on G2.com.

Occasional connectivity issues, nonsense 137 OOM and infrastructure failure which result in build failures with no part on our end. That costs us credits. 137 OOM error happens from time to time to our Node.JS application when their dashboard resources show that RAM consumption is only 50%. Support engineers do not thoroughly read and understand issues when email them at support@circleci.com and reply me with totally different context about the problem. Just yesterday, my web applications fail to `yarn build` after I downgrade the resource class from xlarge to large. Contacted support but no reply.

Billing is a fucking mess and nightmare! There are duplicate information in the bill downloaded from their website and when I asked for consolidated bill, they just answer don't have it. There is no transparency on how many build minutes and credits I spent each day both on their website and the monthly bill which make it difficult to understand when the monthly bill contains many refill item charges. It is difficult or impossible to track usage and burndown of my subscription and total outstanding refill amounts on a daily basis. For example, I went through the build history for the 3 days into the new billing cycle. There were a total of 74 build and when I sum up the duration of the build, it is 597m 41s. However, their fucking rubbish dashboard shows 4265 "Compute" minutes. Is this a SCAM? Review collected by and hosted on G2.com.

The free tier of CircleCI includes 30,000 which is usually enough for small projects. It is pretty easy to use it once u get the hang of including CircleCI in your projects. You can even SSH into the build so that if any issue arises you can solve it directly in the machine, instead of trying to figure out where the issue is locally.

The initial setup for CircleCI can be a bit more complex when compared to other tools like Github actions, but it's nothing that a bit of introspection cannot solve. Also when using Docker layer caching the credits run out too fast. There should be a warning for the same , since I did not realize that caching would use so many credits.

The simplicity: the entire CI pipeline can be configured in a single YAML file.

Parallelism support: I also love the CIrcleCI CLI which gives the ability to split the execution of automated tests between multiple containers. This is a game-changer. The tools can split the tests intelligently, based on historical completion time data.

The "Insights" section in a CircleCI workflow is remarkable. It provides robust data to help understand quickly why, how, and when tests are failing.

Finally, I am grateful for the CircleCI support team. The support engineers are quick to answer and super friendly. Review collected by and hosted on G2.com.

I have not seen the ability to add variables to a manually triggered workflow, which can be helpful when a user triggers it in the UI. It is something that is supported in GitLab CI. Review collected by and hosted on G2.com.

Their UI is great. Setting up the CI pipeline, with all the docker features and different options makes it a great option to have in you CI pipeline. We use it in all of our repositories and help us run all of our test with each commit and PR Review collected by and hosted on G2.com.

There's really nothing that comes to mind as something negative about CircleCI. Sometimes the CI setup requires some updating (some old versions stop beign supported, etc), but CircleCI makes it super easy Review collected by and hosted on G2.com.

Intuitive and easy to navigate, and after working with it, I got used to it.

At our place, we use it for builds on every commit push and deploy jobs to different envs.

It's fairly simple, has slack and github integration, setup is easy (way easier than Jenkins at least) Review collected by and hosted on G2.com.

Sometimes there's a timeout or page doesn't refresh telling you the status of a build.

Apart from that, not many issues. Review collected by and hosted on G2.com.

Since we moved to circle CI we have saved many hours of work. It even allows to do this concurantly which allows our deployes to be event faster.

We have checked out many other platform, but just love the service and pricing Review collected by and hosted on G2.com.

We really lack the ability to cancel a job when we start a new one, altough this is possible on a project settings it is not possible on a per branch or workflow. Review collected by and hosted on G2.com.

Its seamless integration with popular version control systems like GitHub and Bitbucket. This allows developers to quickly set up and configure continuous integration and delivery pipelines for their projects.CircleCI also provides excellent scalability and performance, allowing for efficient parallel execution of tests and builds. Overall, CircleCI offers a reliable and robust CI/CD solution that dramatically simplifies the process of automating software builds, tests, and deployments.

CircleCI primarily focuses on cloud-based CI/CD workflows, which may not align well with specific local development or on-premises deployment scenarios. This can be a limitation for organizations with specific requirements. Review collected by and hosted on G2.com.
