CloudBees CI vs Semaphore

CloudBees CI is a centrally managed Jenkins environment for teams delivering continuous integration at scale. It can run on-premise or in the public cloud, with a modern cloud platform designed for Kubernetes and a traditional platform edition. Operations Center provides a central view across CI controllers. Pipeline capabilities include complex delivery pipelines, declarative syntax, and builds that can survive controller and agent failures. The CloudBees Assurance Program vets plugins, while Beekeeper helps administrators monitor and manage plugin upgrades. Documented integrations include GitHub and Bitbucket, plus Slack and Microsoft Teams. Security options include central management, role-based access control, single sign-on, and connections to external credential stores such as CyberArk and HashiCorp Vault. CloudBees CI is paid, with pricing available on request, and has no free plan. 24/7 expert support depends on the customer’s support agreement. CloudBees support policies cover only CloudBees-certified plugins on services based on Jenkins core.

Semaphore is an AI-native CI/CD platform for building, testing, releasing, and deploying code. Teams organize automated development tasks into workflows containing one or more pipelines. Its visual Workflow Builder represents pipelines, creates YAML configuration, and displays performance feedback. Repositories can connect from GitHub, GitLab, or Bitbucket. Teams can use hosted jobs or run self-hosted agents on Linux, macOS, or Windows; those agents can autoscale with Kubernetes or AWS. Semaphore is open source under Apache 2.0 and can be self-hosted. The default concurrency is 20 jobs, with higher limits available on request. Artifact use is free up to 20 GB monthly egress and 100 GB monthly storage; additional usage is charged separately. A free plan includes account, project, and Git integration assistance, while advanced CI troubleshooting is offered through paid support. Listed paid support begins with Basic Support at $50 a month. Semaphore says data is encrypted in transit and at rest, and that it holds SOC 2 Type 2 and ISO 27001:2022 certifications. Pricing includes free usage credits and per-minute compute charges.
