Migrate your CI/CD from Jenkins to CircleCI
Join thousands of developers who have made the switch from Jenkins to CircleCI. With CircleCI, you can:
- Automate testing and deployment
- SSH into failed builds for easy debugging
- Automatically maintain third-party integrations with orbs
- Manage multiple projects with reusable config
- Use workflows for simple job orchestration
- Host CircleCI on-premise or in your private cloud
CI/CD designed for speed, at scale
Save time on maintenance and management
Instead of managing user permissions across multiple tools and platforms, CircleCI helps teams eliminate redundancy and reduce risk by handling everything on the VCS. Use orbs to further simplify project management and to easily set up and maintain third-party integrations.
Increase productivity
On Jenkins, teams of on-call engineers often spend their time installing dependencies and troubleshooting complex issues. On CircleCI, all builds start in a clean environment and can be quickly debugged with SSH access. And, features like parallelism and customizable RAM and CPU help teams maximize build efficiency across projects.
Reduce operational overhead
Plugins are required to do almost anything in Jenkins, even to check out a Git repo. CircleCI saves you the trouble of managing and installing plugins, because all core CI functionality is built-in, including first-class integrations with GitHub and Bitbucket.
Create consistency across projects
Treating CI configuration like any other source code makes it easy to manage and share. All environment variables you store inside CircleCI are encrypted at rest and sent to your build containers using SSH. And, with orbs, you can condense repeated pieces of config into a single line of code to use across multiple projects.

Setup
- VCS authentication directly from the UI
- Import repositories as projects*
- Declarative YAML configuration for all features, defined in a single config.yml file
- Reusable code snippets to simplify multi-project setup and maintenance
- Install Jenkins on CI machines and plugins for VCS integration, UI, and any additional functionality
- Troubleshoot plugins for cross-functionality
- String together functionality from plugins with varying syntax and best practices
Maintenance
- Use out-of-the-box solutions to easily set up and maintain third-party integrations
- Use new features as soon as they are released
- Maintain machines and individual plugins with varying release cycles and support
Performance
- Allocate more CPUs + RAM to complex jobs
- Cache dependencies, Docker layers, and more to speed up build time
- No slow-downs from individual features
- SSH into failed builds for fast debugging
- Dependent on efficiency of plugins
- Manually tweak plugins or upgrade machines to increase performance
Permissions
- Add users via VCS authentication
- Automatically adopt permissions from VCS
- All users given full access by default
- Manual setup of permissions
Security
- Application-level security + runtime isolation
- Additional security layers protect source code, environment variables, and outputs
- SOC 2 Type II and FedRAMP certification
- Single-layer of security surrounding CI fleet
- Additional security created manually
- Varying levels of security for OSS plugins
Hosting Options
- Choose Cloud for best in class Cloud Native CI/CD and the option to use self-hosted runner for your own infrastructure
- Choose Server to self-manage with complete customization and control
- Basic cloud CI features, Self-hosted runner functionality at early stage development with infrequent release cycles
- Intended primarily for self-hosted use cases, with time intensive maintenance
What our customers have to say:
“CircleCI를 사용함으로써, Jenkins의 유지 관리 비용으로 아마 7만 5천 ~ 30만 달러(USD)를 절약할 수 있었습니다. 또한 두통도 줄어들었고 배송도 간편해졌습니다.”

Get instant access to our top features
Host CircleCI on-premise or in your private cloud
Choose our cloud-hosted option for increased flexibility, instant access to feature releases, automatic upgrades, and more. Or, host CircleCI on a private server for maximum security and maintenance control.
Automated testing and deployment
CircleCI automatically runs your pipeline in a clean container or virtual machine so you can test every commit. Passing pipelines can be set up to automatically deploy to various environments so your product goes to market faster.
SSH into failed builds for easy debugging
Quickly find and solve problems using SSH access into failed builds, or run jobs in your local environment to make it easy for your team to find bugs and solve issues before they hit production.
Use orbs to set up and maintain third-party integrations
Orbs are reusable snippets of code that help automate repeated processes, speed up project set up, and make it easy to integrate with third-party tools. Use an orb to deploy to AWS or GCP, manage K8s, test code coverage, and more.
