Build your own CI/CD

Cross-Platform CI/CD

Run agents on Linux, macOS, or Windows with simple install commands. For heavy workflows, deploy on-demand agents using Kubernetes cluster with our custom controller Helm chart, or use the agent-aws-stack for an auto-scaling fleet on AWS.

Unidirectional communication ➡️

Communication always goes from the agent to Semaphore. We will never force you to open your firewall to the Internet.

Encrypted by default 🔑

All communication, tokens, messages, and logs are fully encrypted. Enjoy the enterprise-level of security offered by Semaphore.

Open source 😃

Semaphore agents are built in the open. Your security team can review and approve every design decision.

CVE discovery ⛔

If any CVE is discovered, Semaphore gives you the ability to shutdown and block all affected agents.

Operation halting ✋

You have full control. In case your team notices something suspicious, Semaphore offers a master switch that instantly and completely halts all operations.

Only necessary access 🛡️

Semaphore follows the principle of least privilege. Every token that is used for communication is restricted to the minimal sets of actions it needs.
