Devops Engineer at EDAG
It is highly scalable, as it is not on our system, so we do not need to take care of the runners as well.
Senior Dev Ops Engineer at 11 East Capital
In the cloud version, CircleCI allows you to go from running one job to 1,000 jobs instantly, so it is very robust.
Software Engineer at a tech services company with 51-200 employees
Previously, only one or two applications could run on a server, but now it can handle hundreds of applications, scaling up or down as needed.
Senior Cloud Engineer - AWS at Bytedance
Docker's scalability is such that the more I use it, the more battery it uses, and that is the only metric that matters to me.
Senior QA and Developer
 

Stability Issues

Sentiment score
8.1
CircleCI provides stable, reliable CI/CD operations with high uptime, minimal disruptions, and is trusted for critical workflows.
Sentiment score
7.8
Docker is generally stable, rated 8/10, but users face memory, compatibility, and security issues, especially on macOS.
It is most important for CircleCI to be stable and reliable because we run a production environment on it.
Devops Engineer at EDAG
We are using this software as a service solution, and if it goes down, the whole engineering stops working almost—we cannot push anything, and building does not work at all.
Software Engineer at a tech services company with 51-200 employees
Overall, CircleCI has been stable and reliable for our needs at Ericsson in different telecom projects.
Technical Solution Support Development Engineer at Ericsson Global
Docker feels like it is stable, but it also feels like it consumes a lot of battery.
Senior QA and Developer
 

Room For Improvement

CircleCI faces challenges with pricing, complexity, and support, needing better UI, AI, integrations, documentation, and troubleshooting.
Docker needs improved documentation, stability, features, user interface, performance, security, integration, and management tools to enhance user experience.
I think there is also UI clutter; with very complex pipelines running with hundreds of steps, it becomes difficult to navigate in the web interface.
Software Engineer at a tech services company with 51-200 employees
If CircleCI implemented a function approach similar to GitHub Actions, it would be significantly better.
SRE coordinator at a financial services firm with 201-500 employees
CircleCI should leverage the growing trend of AI by offering an out-of-the-box AI-driven dynamic YAML file creation feature using natural language processing.
Managing Technical Consultant - Solution Architect at NTT DATA
Docker is a time-tested, proven solution with industry-wide applications.
Senior Cloud Engineer - AWS at Bytedance
The main thing that really frustrates me about Docker is how much battery power it consumes on a Macintosh.
Senior QA and Developer
A more guided approach to using it would be useful.
Ed Tech Project Manager at Aulab
 

Setup Cost

CircleCI's enterprise pricing is variable and manageable, but transparency issues and high charges can occur without monitoring.
Enterprise buyers benefit from free Docker, but larger teams may need paid plans for additional support and features.
A large server costs more credits per minute than a small one, but there is a risk that some scripts or an infinite loop can burn through $500 of credit in a weekend if you do not set up spending limits or alerts.
Software Engineer at a tech services company with 51-200 employees
So far, we have been able to keep everything within our organization's budget.
VP at Tech 3 60
The pricing varies depending on how we use the pipelines, which run frequently, leading to variability in costs.
Cloud Platform at Futurescape
I consider Docker's pricing to be affordable.
Software Engineer at a tech services company with 51-200 employees
 

Valuable Features

CircleCI offers YAML configuration, GitHub/GitLab integrations, Docker support, fast execution, and seamless DevOps integration for efficient CI/CD processes.
Docker enables efficient, secure containerization, offering portability, scalability, and user-friendly management for streamlined deployment and application customization.
The GitHub integration is most valuable because of its ease of use, as it only requires integration with the GitHub repository and then creating the pipeline as a YAML file within the repository code.
SRE coordinator at a financial services firm with 201-500 employees
Among those features, I find the most valuable in my day-to-day work the automation aspect, as we have a large product team with many developers who continuously create branches and push code, necessitating automation that builds the pipeline and the branches automatically while giving faster feedback.
Managing Technical Consultant - Solution Architect at NTT DATA
Running parallel jobs where dev gets automatically updated every time has helped our team significantly.
Senior Dev Ops Engineer at 11 East Capital
It allows the software to run on various machines without compatibility issues, saving a lot of time.
Senior Cloud Engineer - AWS at Bytedance
The most important feature is environment consistency across all stages, and the ability to guarantee identical environments in development, testing, staging, and production.
Ed Tech Project Manager at Aulab
The most valuable feature is the simple containerization.
Software Engineer at a tech services company with 51-200 employees

Featured Reviews

Arka Sarkar - PeerSpot reviewer
Technical Solution Support Development Engineer at Ericsson Global
Automated pipelines have accelerated microservice delivery and improve release consistency
Debugging is an important point for improvement because when pipelines fail, debugging can sometimes be difficult, especially for the complex workflows which we have already faced in our organization in different projects. Logs are available, but root cause analysis can take time, so that can be improved. Also, configuration management challenges exist. Although YAML configuration is flexible, it can become complex and hard to maintain as pipelines grow in size and include multiple workflow conditions. The limited visibility for large pipelines is also a concern. For very large enterprise pipelines, the UI can feel less intuitive in terms of tracking dependencies and understanding the full workflow at a glance. Cost optimization is one important point for improvement. In cloud-based usage, costs can increase due to long-running jobs and inefficient pipelines. Proper optimization through caching and parallelism is required, otherwise it can become expensive, which we faced in one of our telecom projects last year. One thing CircleCI can improve is related to cloud runners, where any network or platform issues can impact pipeline execution. This can be a concern for critical telecom deployments.

Local container testing has boosted development speed but still needs lower battery and memory use
The main thing that really frustrates me about Docker is how much battery power it consumes on a Macintosh. I really am not a fan of that, which leads me to not want to run Docker 24/7 because I do not want my laptop battery to be exhausted by Docker instances running or even the Docker CLI or UI being booted up. I tend to not have it running until I need it, and then I run it and close it. It would be really nice if it did not consume as much battery as it does currently. Docker can definitely be improved by reducing the battery and CPU load that it impacts on a Macintosh. If it were possible for me to run Docker without panicking about the battery running out, that would be excellent. I believe battery is the biggest issue with Docker. The other issue is memory. It seems to consume a lot of memory, and I am not a fan of that. This means that I need to have a really powerful, high-specification Macintosh with a lot of battery and a lot of memory for it to work reliably. I do not always have access to that. If Docker could consume less battery and less memory, that would be magnificent.
