Migrate your CI/CD from GitHub Actions to Semaphore

  • ✔️ Run 2x faster builds
  • ✔️ See your entire path to production in a single CD view
  • ✔️ Always have CI/CD experts at hand to support you

Cut your build times in half using Semaphore’s top-of-market machines and advanced pipeline features. Considering how often developers push code in a month, the ROI of switching to Semaphore is 41:1 (see whitepaper).

On Semaphore, a graphical workflow builder puts high-performance CI/CD into the hands of every developer. Test insights empower the team to keep the project sustainable, while fast SSH debugging enables fast error recovery in daily work.

On Semaphore, CD is not limited to a series of after-build steps. Features like parameterized promotions and deployment queues give you the power and flexibility to make deploys to any environment completely painless.

For us, CI/CD is not an afterthought. You can always count on Semaphore as a trusted partner who will go the extra mile in supporting you in your mission to deliver great software, fast.

“Since moving from GitHub Actions to Semaphore our CI pipeline has been more stable and 2x faster. This allowed us to detect failures and flaky tests faster. Our engineering team is now more focused on core business and delivering features to our customers.”

Case studies

“We were using Jenkins to build the old system, and it was hard to maintain and quite painful. We looked at other hosted CI services, but they were very unreliable. When we found Semaphore, we got our application up and running pretty quickly. We now use it for all projects.”

“Semaphore allows us to build anywhere from two to twenty branches in parallel, each one in a threaded environment. We had thousands of tests that were running for a really long time and with Semaphore we got the build to run in under 20 minutes.”

“Semaphore 2.0 allows us to build, tag, push, and run Docker images easily. This makes building a powerful pipeline where we can deploy to our Kubernetes cluster fairly easily and quickly.”
