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).

Best UX for SaaS CI
Pros: When I first starting using CircleCI with version 1 I loved the simplicity. Every code would execute the commands in a relatively simple yml file. Version 2 is far more powerful and flexible. It took me a while to get used to but I still find Circle's ease of use to make it my choice over others.
Cons: Version 2 has a lot of complexity that can make it hard to get started with. Their Orbs concept is bringing back some simplicity.

CircleCI is a blessing
Comments: CircleCI is crucial to what we're doing and it's powerful. I've enjoyed using it for awhile now.
Pros: It's powerful, it's got lots of features, and the customization is limitless. CircleCI improves the developer experience many times over. It's also fairly reliable, and makes handling a large project simpler.
Cons: It can go down sometimes, debugging can be a bit hard and cryptic. Support is also fairly lackluster.

Comments: It has been a good experience overall, very minor downtimes. It has really helped me and our team to perform continious integration for our projects.
Pros: It let's you automate continuos integration fairly easy by just using a YML file. You can setup many different stages and rules for these stages to have different development environments. It's fairly easy to learn and implement. It integrates very well with Github.
Cons: Have seen a few downtimes in the last couple of months.

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.

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.

automated test do it right
- 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.

CI/CD with few lines
Comments: 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

Great build/deploy tool
Darrell "jeremy" F.
Comments: 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.

I love CI about as much as Circle does
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.

CircleCi has changed how we develop
Comments: 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 use and powerful
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.

One of the best CI tools available
Full customization and scripting abilities. Using tools like bash scripts, SSH, and Node, running almost anything upon committing some code to GitHub becomes possible.
Integration with all of our favorite services. GitHub and Slack in particular are crucial to our business and CircleCI's integration is seamless and full-featured.
Easy to configure via a YAML file
Sends email notifications without the use of external services
Not only runs our tests, but also triggers our deployments
Proactive communication about updates and breaking changes
Questions to account rep can sometimes take too long (for us -- > 1 day) to respond

Powerful CI / CD platform
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.

My favourite tool for continuous integration :)
Pros: 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.
Cons: 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

Circle CI trusted by FB
Pros: Circle CI is being trusted by FB for React, and Fastlane. So if it works for them I think that is a great testament to it.
Cons: Doesn't allow as many languages and environments out of the box as Travis CI does.

Great tool but lack tutorials
Pros: 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.
Cons: The tutorials are not yet clear. They don't lead from start to workable CI.

CircleCI for build/deployment
Pros: 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.
Cons: The learning curve is steep for some developers. It has two versions of the software, which sometimes makes it difficult to manage.

CircleCI is one of the best CI
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.
