CircleCI Reviews in June 2025: User Ratings, Pros & Cons

Great product, wish the builds were a bit faster!

What do you like best? Great docker support. Good UI. Good docs. Good Github integration. What do you dislike? 1. Most of our build time is spent spinning up the environment. I wish that was a bit faster. 2. It would be GREAT if I could exit early from a job without giving an exit error code. Basically I want to skip parts of the job based on certain conditions. Of course I can do this inside a shell script, but some build steps cannot be executed inside a shell. The example I'm ...

A nice continous integration server on the cloud.

What do you like best? Unit testing is the most important element in our software development process, since it guarantees the quality of our product, but at the same time, is the most time consuming since we have around 8,000 tests and take around 30 minutes to run in a fast computer. When run, they are very resource intensive, so the developer can't do much while they are running. CircleCi takes care of it for us and notifies us in case something goes wrong. What do you dislike? ...

Great tool for integrated testing

What do you like best? It can easily be set up with GitHub, and from there makes sure a new feature to be pulled in the main code base doesn't break any of the tests that have been set up. What do you dislike? It's probably not a circle-ci thing, but when first introduced to circle-ci and not doing the actual set up of it as a junior it can be a learning curve. When you have failing tests in the circle ci it can be hard to see the errors or know which commands to run depending on the test ...

Great for Deployment

What do you like best? I love how easy it is to deploy a public repository to a private server while hiding all sensitive content. Travis CI does not allow for this. The builds are also significantly faster than other platforms, and the UI is modern unlike some of the other competitors. I am surprised this isnt more popular among open source communities as it is pretty much free for both private and public repositories. What do you dislike? I'm not a fan of their new 2.0 system. I find ...

Hard to setup and goes down a lot

What do you like best? The automatic pairing with Github is really slick, especially as I add more repos over time. What do you dislike? It's super complicated to setup anything more than a default build, especially with the new 2.0 configuration. There also seems to be a ton of downtime or partial outages, and no compensation is given when this happens. Recommendations to others considering the product: If you need to build against multiple versions of a library/language (such as Ruby, ...

Awesome CI tool which can easily be configured to fit needs of small to large scale projects.

What do you like best? - Easy to get up and running with a basic configuration - Lots of options to improve your configuration - Possibility to SSH into build containers to debug issues - Fair pricing - Fast e-mail support What do you dislike? - Product roadmap could be more transparent. The switch to CCI2 was pretty well executed, but I'd love to get more involved in plans for new features, bugfixes etc. Some kind of Changelog would be nice. - I sometimes feel like the ...

CircleCI is what CI should be

What do you like best? Workflows and how easy it is to parallelize build jobs. I didn't have to ask devops to set up anything! What do you dislike? We have services behind a VPN that public CircleCI cannot access. This is likely solved by CircleCI Enterprise but so far I haven't been able to get Devops to set this up for us. Recommendations to others considering the product: Hook it up to one of your open source projects and try it for free. It really is great! Take the time to ...

It's a fantastic way to automate almost any project from testing to deployment

What do you like best? The workflows and ability to run different sets of tests or types of tests on a single repository is fantastic. You can have both your javascript frontend code and python backend code in the same repository and run tests and deployments on them both. What do you dislike? The pricing model is a little confusing for the cloud-based setup in terms of deciding what you really need. Recommendations to others considering the product: Check it out. Their support team has ...

Great tool for increased development productivity

What do you like best? The ability to parallelise different aspects of the build flow and increase build speed considerably especially for larger scale applications. Additionally the ease of iterating the workflows by introducing minor changes and being able to test those quickly against specific branch build made it super easy for us to improve our build over time whilst using it. What do you dislike? There's nothing to properly dislike! The general interface could do with some ...

The Easiest CI

What do you like best? I like circle ci with the ease of it's implementation, doesn't have to learn the whole new things, it's also provide us with ssh access to your build which can be helpful sometimes to debug your problems, and you can do it with a single click. What do you dislike? I can't control how many cpu that circle ci use for my build, or I don't know how, maybe I just need to read the docs, i'm just too lazy. Recommendations to others considering the product: Take it, it ...
