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.
CircleCI is perfect for a CI/CD pipeline for an app using a standard build process. It'll take more work for a complex build process, but should still be up to the task unless you need a lot of integrations with other tools. If you have a big team and can spare someone to focus full time on just the CI/CD tools, maybe something like Jenkins is better, but if you're just looking to get your app built, tested, and delivered without a huge amount of effort, CircleCI is probably your preferred tool.
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
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.
The "phases" their config file uses to separate out options seem very arbitrary and are not very helpful for organizing your config file
No way that I know of to configure which version of MongoDB you use. You have to write your own shell script to download and start MongoDB if you want a specific version.
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.
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.
Circle was the first CI with simple setup, great documentation, and tight integration with GitHub. Using Jenkins was too much maintenance and overhead, TeamCity was limited in how we could customize it and run concurrent builds, TravisCI was not available for private repos when we switched.
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.
It has eased the burden of standardizing our testing and deployment, making onboarding new developers much faster, and having to fix deployment mistakes much less often.
It allows us to focus our process around the GitHub workflow, ignoring the details of whatever environment the thing we're working on is actually hosted in. This saves us time.
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.
