Semaphore
Novi Sad, Serbia
What it is
Semaphore is a CI/CD platform for automating code builds, tests, releases, and deployments. A workflow can contain one or more pipelines for development tasks, while its visual Workflow Builder models those pipelines, generates YAML configuration, and provides visual performance feedback. Teams can connect GitHub, GitLab, or Bitbucket repositories and choose hosted jobs or self-hosted agents on Linux, macOS, or Windows. Self-hosted agents can autoscale with Kubernetes or AWS, and the software can also be self-hosted under the Apache 2.0 license. Semaphore lists 20 concurrent jobs by default, with higher limits available on request. Artifact use is free up to 20 GB monthly egress and 100 GB monthly storage; extra use is charged separately. Semaphore says builds run in isolated sandbox virtual machines that are destroyed after use. Its free plan includes support for account setup, projects, and Git integration, while advanced CI troubleshooting is part of paid support. Plans include free usage credits of $15 monthly; pricing varies for compute and support options.
