CircleCI is a software delivery engine from the company of the same name in San Francisco, that helps teams ship software faster, offering their platform for Continuous Integration and Continuous Delivery (CI/CD). Ultimately, the solution helps to map every source of change for software teams, so they can accelerate innovation and growth.

Based on our experience, CircleCI is well-suited for automating mobile app release cycles. For example, to release an iOS app, you would need to build, sign, and upload it to TestFlight, which requires a dedicated Mac in the office. But with CircleCI, you can have macOS executors, so you don't have to manage a physical build machine. Another benefit is that CircleCI's certified AWS Orbs abstract away complex authentication and deployment logic, allowing us to build, push, and deploy Docker containers to Amazon ECS with minimal configuration and high reliability. CircleCI is less suited for smaller projects where the development and deployment are not that extensive, for example, a static site. Once you have built a static site, you probably won't make any further changes, so there's no point in paying for it.
Mostly it is very suitable for any product based company who wants to add a CI system for their products. This tool is perfectly suitable for a company which releases builds very frequently. By using this tool they can reduce a tremendous amount of manual effort. If company's budget is not high and if they can not afford the premium plan then this tool won't be suitable for them because the basic version of this tool won't provide much functionality
Automated builds! This is really why you get CircleCI, to automate the build process. This makes building your application far more reliable and repeatable. It can also run tests and verify your application is working as expected.
Simple. Unlike Jenkins, Teamcity, or other platforms, CircleCI doesn't need a lot of setup. It's completely hosted, so there's no infrastructure to set up. The config file does take a bit to understand, but if you follow their example and start with something small and add to it, you can get it up and going quicker than it first looks.
Scales easily. Again, since it's all cloud-based, you don't have to manage or scale infrastructure. Simply subscribe to the number of containers you want, and scaling up just means buying more containers.
First thing is this tool is scalable which is the biggest advantage of this tool. It won't take much time in setup and making it ready. It has a very good user interface.
This tool has almost every source code repository support like Git, SVN, Microsoft Foundation Server etc. Moreover, it has very good support for various build tools like Visual Studio, MSBuild etc., which makes it even batter.
We can trigger multiple builds at a time with the Premier subscription.
It allows users to apply many deep levels of configurations which make the whole system even easier.
Mostly I don't have much more recommendation for improvement because this tool provides almost everything which would be required in any continuous integration system. But still I would suggest improvement in the reporting system. The build report is a field where they can make improvement by adding more information if they want.
The reliability & speed, it just works. The ability to spin up macOS runners and Docker containers on demand without managing hardware is a huge win. The Orbs system makes integrating with AWS and Slack incredibly easy, saving us weeks of custom scripting and providing real-time updates in our Slack channel. This makes it easy for us to track and ensures that everyone involved knows the status. Of course, it has drawbacks related to configuration complexity and, in some cases, cost transparency, but overall, it is an industry-standard, robust tool that solves our core infrastructure problems well.
It's pretty snappy, even with using workflows with multiple steps and different docker images. I've seen builds take a long time if it's really involved, but from what I can tell, it's still at least on par if not faster than other build tools.
Unless you have a reasonably large account, you're going to be mainly stuck reading their documentation. Which has improved somewhat over the years but is still extremely limited compared to a platform like Digital Ocean who invested in the documentation and a community to ensure it's kept up to date. If you can't find your answer there, you can be stuck.
Jenkins is usually self-hosted, Travis CI's infrastructure is largely unreliable (lots of tests time out for no discernable reason), and Semaphore encourages you to configure your CI/CD from a web UI. We like CircleCI because its hosted, our tests run largely as expected on their infrastructure, and we can configure it from a config file that we track in GitHub.
In my previous company I have used Jenkins for maintaining their CI system. Even this tool is also very good. The good thing about this tool is it’s an open source project. So in terms of pricing, we can consider this tool as an alternative to continua CI. One has to compare both of the products before going to use any one because both have their own benefits and drawbacks.
We pay over $5K/ month and we have high expectations for service. Sometimes I feel that we don't get the value, but only sometimes.
We have had to build our own application to keep state and broker releases and deployments. We call our app deployer. I feel that CircleCI could do more to understand our needs and possibly build additional features that would enable us to invest less in build and deployment infrastructure and justify paying more for Circle.
Basically, this tool will reduce manual effort of creating, deploying and testing software products. So ultimately it will reduce manpower which would otherwise be required for such things.
It is time saving and improves the overall performance of the entire team and system.
