Semaphore

CI and deployment built for speed and simplicity

Find bugs before they reach your users. Semaphore automatically runs your test suite every time you push new code to GitHub quickly and reliably. It then updates the build status on pull requests so you know if it is safe to merge. Semaphore can also automatically deploy successful builds to production and provide a shared changelog for your team. You will never want to set up a CI server from scratch again.

Features

Get started quickly

Set up continuous integration in a minute. With Semaphore's automatic configuration for a wide range of projects you can run the first successful build and invite your collaborators in a few clicks. It works without any configuration files or changes in your source code. And it's easy to customize with any additional configuration or system dependencies that you need.

Run your tests really fast

To ensure the fastest possible test run time, Semaphore runs your tests on bare metal hardware. If you have large test suites, you can easily cut your test time in half or more with parallel threads. Semaphore helps your project move forward fast, with a peace of mind.

Move faster with continuous deployment

By providing a safety net for the entire team, Semaphore makes it easy to deploy as soon as possible. Always be confident to push new code, run tests, roll out a feature and quickly get feedback from users. Use Semaphore's built-in integrations with Heroku, AWS and native Docker support to quickly set up deployment pipelines. Manage different staging and production environments with a nice overview of who deployed which feature on what server and when.

Get notified on every important event

Semaphore has built-in integrations with popular group communication tools such as Slack, Hipchat or Campfire, so that your team is always in the loop. Know when the build failed, was fixed or deployed on a specific server.
