About Semaphore UI
Semaphore UI is a web interface for running Ansible, Terraform, OpenTofu and other DevOps tools. It turns routine operations into workflows that your team can run, schedule and audit.
What it does
Semaphore UI gives a team one place to run task templates, schedules, inventories and variable groups. Work can be kept in Git and run from the interface, with logs showing what ran, who started it and whether it succeeded. Approved users can run checks or restarts without needing server access. The project also has an API and supports notifications, so it can fit into an existing toolchain.
Key features
- Task templates for Ansible, Terraform and scripts
- Schedules for recurring jobs
- Logs for every run
- Access control for approved users
- API and notifications
Who it's for
Operations and IT teams that run the same tasks many times and want to share them safely. Infrastructure teams who want to stop being the bottleneck for routine requests will also find it useful.
Pricing and good to know
Semaphore UI is open source under the MIT licence and is free to use. It is self-hosted and can run on Linux or Windows, with Docker, or on Kubernetes using a Helm chart. Paid Pro plans add more features, and a Pro trial is offered on the site. Keep the server secured, because it holds the credentials needed to run your automation.
