Semaphore
Semaphore is a modern web interface for Ansible that lets homelab users run playbooks, receive failure notifications, and control access to deployments.
Platform availability
Available on 4 of 9 platforms
Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

First-install notes
- Create the Semaphore database first For a MySQL install, install MySQL and run CREATE DATABASE semaphore CHARACTER SET utf8 collate utf8_bin; before setup. This is where Semaphore stores projects, users, and task results, so setup will fail if it is missing. source
- Run the interactive setup wizard Run semaphore -setup (or semaphore setup) to enter the database login and the folders where your Ansible playbooks live. Without this config step, Semaphore cannot find its database or the files it should run. source
- Start the server after setup Run the start command for your installed binary, such as ./bin/semaphore server, so the Semaphore service is actually running. If you forget to start it, the installation looks complete but the service is still offline. source

Common questions
What port and initial login should I use for the quick Docker/SQLite start?
The quick start publishes port 3000 and uses the initial login admin / changeme. It stores data in the mounted /var/lib/semaphore volume when using SQLite.
Do I need to create the database before setup when using MySQL?
Yes. Create the semaphore database with CHARACTER SET utf8 and collate utf8_bin before setup. It stores projects, users, and task results, and setup fails if the database is missing.
Why might Semaphore not respond after setup completes?
The service may still need to be started with a command such as ./bin/semaphore server. If it is not running, the installation can look complete but the service remains offline.
Does Semaphore retry if a Git server is briefly unreachable during a task?
Yes. If the Git server or network has a transient outage, Semaphore retries clone and pull operations automatically before failing the task.
