What are some alternatives to Jenkins and CircleCI?
Easy to setup, great flexibility, awesome support

After trying several CI systems, we stuck with CircleCI because of the inference engine in CircleCI 1.0 made setup a breeze. We were up and running quickly. Builds are reliable, nicely integrated into GitHub, and anytime we've had a question, the support team was there to help. The 2.0 system provides Docker support and far more customization and is still fairly easy to set up with helpful documentation.
Easy to use and super quick

I use CircleCI as part of a cross platform mobile app to build and test the app as well as deploying .apk files to an s3 bucket.
Alongside CircleCI this repo also has a TravisCI setup for iOS. The CircleCI build has always been quicker and since moving from CircleCI v1 to CircleCI v2 it blows the TravisCI build out of the water. I'm really impressed with the performance gains from moving to v2. I'm pretty sure I could achieve similar results in Travis as well, but it was really easy to setup the Android CI build in Circle making use of Docker.

CircleCI has become our CI of choice. The UI is really good and it has all the integrations we need. The 2.0 upgrade was not yet possible for one of our projects due to outdated gems, however, I have been able to get it working for a different one.
CircleCI is an integral part of our CD pipeline
February 28, 2018 12:23
We use it to test every commit we push to github and deploy everything we merge into master for every project.
Easy to Use CI/CD

We use CircleCI to deploy to server. It is much easier than other websites like Travis especially for the free tier. It is especially useful for open source projects that need private access behind the scenes.
Easy to use

It help us with the automated build and test and also provide us with the build artifacts which we can use for the deployment also give use archive for each of our build, this things save us alot of time and cost
Full featured but hard to use

There's a lot of awesome features in CircleCI but it's generally hard to use and figure out. In addition, there seems to be some reliability issue, especially in connection with their third party dependencies.

Oomba uses CircleCI
CircleCI automatically runs all unit and e2e tests, as well as packaging and deploying builds to our live servers.
AngeloR uses CircleCI
We originally used CircleCI as our self-contained build system for our internal node modules. It was very easy to set up and configure. Unfortunately we ended up stepping away from it to Jenkins and then CodePipeline due to better integration with our various applications.
jflynn33 uses CircleCI
We prefer CircleCI because we care about testing our apps. We found it is better to invest the time writing rSPEC tests to ensure we don't insert any regression bugs with new branches. It's also nice to have a fully-automated deployment process from GitHub to Heroku.
PayParty uses CircleCI
We use Circle CI to do test and build automation. And also, do our deployments in stage and prod env.
