Level up developer productivity & happiness
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.
Adopt end-to-end Continuous Delivery
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.
Have a partner – an extension of your team
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.”
