Semaphore UI gives your team one self-hosted place to run,
share, schedule, secure, and audit operational workflows.

PythonUse Semaphore UI with Ansible, Terraform, OpenTofu, Terragrunt, Bash, PowerShell, and Python, while keeping your automation in Git and your existing toolchain intact.
When routine ops pile up, it is easy to miss steps, lose context, or overlook failures. Turn recurring jobs into reusable workflows with inputs, secrets, schedules, logs, and access control.
When jobs fail or incidents happen, missing context slows everyone down. See what ran, who launched it, when it happened, what changed, and whether it succeeded or failed.
Infra teams should not be the bottleneck for every routine request. Let approved users run checks, restarts, and cleanups without Linux access, SSH, credentials, or CLI.
Deploy Semaphore UI on Linux or Windows, with Docker, or on Kubernetes using the official Helm chart — and keep it easy to maintain.
Everything your team needs to run automation day to day: tasks, logs, schedules, Git, API, and notifications in a clean UI without unnecessary complexity.
Run Semaphore inside your own network and keep all operational data under your control.
Host Semaphore on a server, VM, container, or Kubernetes cluster.
Written in pure Go, Semaphore is simple to deploy, update, and maintain.
Work across Windows, Linux, and your existing automation stack.
Keep scripts, playbooks, and IaC projects in Git, then add templates, variables, credentials, and inventories in Semaphore's UI.
Manage projects, templates, inventories, and more with Terraform, so setup changes are easier to review, repeat and maintain.
Use the Semaphore MCP server to inspect and update projects, templates, inventories, repositories, schedules, and task context.
Schedule patching, backups, checks, cleanup, and other routine jobs with run history and logs.
Connect jobs, approvals, dependencies, and handoffs into repeatable workflows.
Start tasks from CI/CD, incident tools, and other workflows through Semaphore's API.
Store SSH keys, tokens, passwords, and sudo credentials in the encrypted Key Store, or connect HashiCorp Vault, AWS Secrets Manager, Azure Key Vault, and more.
Use RBAC, projects, LDAP/AD, OIDC, and custom roles to give people the right level of access.
Review status, output, errors, logs, and run history to debug failures and verify changes.
Send job updates to Slack, Teams, email, or webhooks.
Execute automation on tagged project runners inside the right subnet, private network, or isolated project environment.
Use high availability, disaster recovery, backups to keep Semaphore reliable in production.
Use Pro support to resolve issues faster, or add Enterprise onboarding, migration help, and guidance to ramp up your team.
“I’ve been testing its features and I really like this app. It has everything I need to run my ansible playbooks: log viewer, scheduler, github integration, and slack alerts…”
“Semaphore and Netbox is all you need. No extra containers or helpers. Semaphore executes the Ansible Playbooks, by pulling them in from a Gitlab Repo in our case…”
“As I said my main use is to view failures on scheduled items and address them as well as seeing the historic failures as a trend. I am sure there are ways to do this on the cli but it was so easy to set up semaphore that I kept going with it.”
“I’m running it on prod at work. The OSS version. Works fine for us. Using it for ansible, some power shell stuff and terraform. Also, using the integration feature to act as a webhook so external entities can start the templates.”
“We use SemaphoreUI, for our ansible needs at my workplace :) What we needed was a tool, that would allow non linux users to run predefined playbooks, and only call us when something fails. Semaphore is great for that :) What we also needed, was a tool, that was easy to set up, and didn't require a whole fleet of servers just to run.”
“I discovered Semaphore UI and started using its scheduling feature to run regular maintenance playbooks. It's been a great way to automate updates, disk checks, and other housekeeping without writing extra cron jobs or scripts.”
“I run semaphore UI over GitHub actions as I feel like it’s a better UI over tracking job status as a whole and I like that I can maintain things like credentials and one-off inventory that I wouldn’t want to manage via git.”
“We are using semaphoreui.com for windows servers. it does powershell quite nicely and ansible as well. No need for complex AAP or AWX deployments where you more or less need K8 just to get started.”
“By the way I absolutely love Semaphore, makes managing all my servers a breeze. Keep up the GREAT work!”

Semaphore UI is an open-source, self-hosted web UI and API for running infrastructure automation. It helps teams run Ansible playbooks, Terraform, OpenTofu, Terragrunt, PowerShell, Bash scripts, and Python tasks from one controlled interface.
No. Semaphore UI supports Ansible, Terraform, OpenTofu, Terragrunt, Bash, PowerShell, and Python. Teams can use the same interface to run playbooks, infrastructure-as-code workflows, scheduled jobs, and operational tasks.
Yes. Semaphore UI is self-hosted and open source. It is written in Go, runs on Linux, macOS, and Windows, and supports SQLite, MySQL, and PostgreSQL.
CI/CD is usually optimized for application delivery: build, test, deploy. Semaphore UI is designed for infrastructure and operations work: provisioning, maintenance, remediation, scheduled jobs, ad hoc runbooks, and repeatable tasks that need controlled execution, variables, credentials, logs, and team access. You can keep CI/CD focused on delivery and move operational workflows into a dedicated self-hosted automation layer.
Yes. Semaphore UI works with your existing repositories and automation. You can define task templates around your playbooks, scripts, and infrastructure-as-code workflows, pass variables, schedule runs, and trigger tasks through the API.
Yes. Because Semaphore UI is self-hosted, your automation, credentials, repositories, inventories, and execution environment stay under your control. Tasks can run on the main Semaphore UI server or on separate runners. With Project Runners in Pro, you can assign dedicated runners to specific projects or task templates, so automation can execute closer to the right subnet, environment, or infrastructure boundary. For stricter security requirements, Enterprise also supports air-gapped/offline and multi-instance license options.
Yes. You can turn restarts, checks, cleanups, diagnostics, maintenance tasks, or recovery steps into task templates, then let the right users run them through Semaphore UI without giving them direct server access, raw credentials, or broad production permissions.
Yes. Semaphore UI supports file-based Ansible inventories, which means you can use Ansible dynamic inventory plugins and external inventory sources as part of your automation workflows. For example, you can pull infrastructure data directly from NetBox using the netbox.netbox.nb_inventory plugin and run playbooks against automatically discovered hosts instead of maintaining inventory by hand. See the NetBox dynamic inventory example in the documentation: https://semaphoreui.com/docs/user-guide/netbox. Semaphore UI can also be used with other Ansible inventory plugins and scripts configured in your automation environment, while still providing centralized credentials, variables, schedules, logs, and task execution.
Semaphore UI includes a Key Store for credentials used by tasks, including repository access, remote host access, sudo credentials, and Ansible Vault passwords. Secrets can be stored in Semaphore’s encrypted database, and Semaphore also supports external secret storage with HashiCorp Vault. For teams with stricter secret-management requirements, Enterprise can use Devolutions Server, AWS Secrets Manager and Azure Key Vault as an external secret storage option. Secrets are passed to jobs at runtime, so teams can run approved automation without exposing raw credentials in scripts, terminals, or shared documentation.
You can buy Semaphore UI Pro directly from the pricing page. After purchase, you receive a license key that can be used to activate Pro features in your self-hosted instance. If your company needs an invoice, bank transfer, custom terms, offline licensing, multiple instances, or Enterprise support, contact the team from the pricing page to arrange the right option.
