A CI/CD tool to accelerate developer velocity

Ship updates 2x faster with our industry-leading performance CI/CD tool.

Shipping updates quickly and reliably is a key indicator of successful engineering teams

Semaphore removes all technical barriers to adopting Continuous Delivery at scale. You won’t need to hire supporting staff or expensive infrastructure. Just define your workflows and focus on building the next great app.

Scale as you go

No servers to manage. CI/CD scales to process your work just in time. You only pay what you use.

Use programmable pipelines

From simple sequential builds to multi-stage parallel pipelines, Semaphore can do it all.

Get ultimate flexibility

Configure your own CI/CD environment with Docker images. Or just use Semaphore’s sane Linux & macOS defaults.

Optimize your monorepo workflows

• Run custom CI/CD workflows for changes on specific files
• Save time by skipping unnecessary build & test stages
