“We’ve moved with Tigera’s open-source product Calico from multi-repo to mono-repo setup with Semaphore.”

“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.”

“Since moving to Semaphore from GitHub Actions, our CI pipeline has been stable and had more consistent run times, this allowed us to detect failures and flaky specs faster.”

“Now that we use more specific conditions and cache specific artifacts, the average duration of the first pipeline (the longest one) is around 4 minutes.”

“It’s faster, more reliable and cheaper. A very rare combination. 15 minute builds down to 2.5 minute builds with parallelization and still cost us less than CircleCI.”

“Running the Ruby gem builds on Semaphore runs perfectly, no random failures, and it’s done a lot faster.”

“Semaphore is a great product, and its focus on performance brings more productivity to our workflow. It has a ton of options for you to build your pipeline. Study the documentation, which is very detailed and covers all the features.”

“We have more control over the CI process and can speed things up. We can now see improvements to our deployment process, given all the features of Semaphore 2.0.”

CTO at SmartPension

“Semaphore is a pretty intuitive platform that has all the features you might need (manual deploys!) which allows for easy parallel test workers setup, so one has fewer things to set up and maintain down the road.”

“It’s way faster and we just pay Semaphore for the number of build seconds we actually use. As we’ve spent a bit of time optimizing our build speed, each build costs about 10 cents.”

CTO / Co-Founder

“Our custom testing script was a pain to maintain and configure, so at some point, we looked into Semaphore and discovered that it can split our tests without us having to maintain anything. We decided to switch to Semaphore, and everyone in the team has been really happy since then.”

Developer at Mynewsdesk

“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.”

“Without parallel tests, our test suite would now run well past the hour mark from start to finish. The ability to split the test suite up across 12 or more jobs in Semaphore and have the test suite run in under 7 minutes is so important for us and it saves us a lot of development time.”

“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.”

CTO at Simply Business

“I started looking at some Open Source tools because that’s what you do these days. Jenkins was out of the question – it was just a horrible piece of monstrosity that I didn’t even want to touch.”

CTO at Kenhub

Read case study

“While there is a lot of interesting and seemingly easy to use solutions out there, very few seem to have really thought out how the CI pipeline will be used and scale beyond small or medium-sized projects and provide the degree of flexibility required.”

Team Lead at Purepoint

“Using Semaphore is very straightforward, it’s incredibly helpful that it’s easy to set up and you don’t have to worry about installing, configuring or maintaining servers and Jenkins instances. It’s all working out of the box, so that lets us focus on writing code and building great FX products.”

QA Manager at Kantox

Read case study

“There are many CI platforms to choose from but I think Semaphore has really struck the perfect balance of speed, stability, and an elegant UI. We have used Semaphore for the past few years and it has continued to meet and exceed expectations.”

“Using parallel jobs, we organized testing files into folders that were loosely based on feature and were able to run all of the tests in around 50 minutes total.”
