Full REST API

Every operation in Semaphore is available through a JSON REST API. No SDK required — use curl, fetch, or any HTTP client.

The case for owning your data

When regulators or clients ask where your team members data is stored, the best answer is a specific server you own in a specific jurisdiction you chose. Semaphore makes that answer straightforward because the data never leaves your infrastructure.

A devops team integrates Semaphore into their CI pipeline. A post-deploy hook creates a teammember record via the API. The stats endpoint feeds a Grafana panel. When something goes wrong, the team searches team members by keyword to find related records without switching tools.

How Semaphore runs

Deploy Semaphore as a systemd service, a Docker container, or a bare process behind tmux. It reads two environment variables: PORT and DATA_DIR. Everything else is self-contained. The /api/health endpoint returns the service status and team members count, which you can wire into your existing monitoring stack.
