Semaphore UI is an open-source, self-hosted web UI and API for running Ansible playbooks, Terraform/OpenTofu/Terragrunt, Bash, PowerShell, and Python automation from a central interface. Written in Go, it provides projects, task templates, scheduling, inventories, secret management, RBAC, and runners for team-based infrastructure automation.
Use cases
- run ansible playbooks from a web ui
- self-hosted terraform automation server
- schedule recurring infrastructure tasks
- manage ansible inventories and secrets centrally
- alternative to awx or jenkins for deployment automation
- trigger devops automation via api
- control team access to infrastructure tasks with rbac
When to choose
- you need a modern web UI to run Ansible, Terraform/OpenTofu, or shell scripts without giving users CLI access
- you want scheduling, execution history, logs, and notifications for automation tasks
- you need centralized inventory, secrets, and access control for a DevOps team
- you want a lightweight single-binary or Docker-deployable automation server
When to avoid
- you need full CI/CD pipeline features like build artifacts and test stages - use Jenkins or GitLab CI
- you only run automation from a terminal and don't need a UI or API
- you require high availability or isolated project runners on the free tier - those are Pro/Enterprise features
