At Semaphore, for years we’ve been happy to support open source projects with a free continuous integration service. Today we’re increasing the free CI/CD capacity on all open source organizations from 2 to 4 Boxes.

Each Semaphore Box comes with one high-end physical CPU (two vCPUs) and 8GB of RAM (4GB of RAM on Docker platform). This provides for a 2x better performance per job comparing to other continuous integration services.

We’re proud to see developers of both community projects like systemd and GNU D compiler, as well as corporate-sponsored work from the likes of Red Hat and Uber being more productive as a result.

Here’s what some of them have said about their experience with Semaphore.

Semaphore is FAST! Also, Semaphore staff has been very personal. I’ve had questions, concerns, and needs over the project, and our communication with Semaphore has always been clear.

The ability to run the tests with full privileges as opposed to other platforms that restrict the environment with technologies like LXC, AppArmor, or containers, and being able to use KVM – often unavailable on other CI platforms that use AWS – is very useful. And of course, the fact that we don’t have to maintain the CI infrastructure with security updates, etc.

We compared our online CI with multiple other online CIs, and we also tried to run our tests on private VMs. We discovered that Semaphore was way faster than any other solution, even faster than our own VMs! Great surprise!

To get the same results, sign up for Semaphore and migrate your project today.

We hope that this will help you build even more awesome software faster.

Happy building!
