Easily automate the process of software testing in the cloud. Make CI results part of your pull request review process, then watch how your team ships working code faster. Best of all? You can get started in a minute.
Leverage 100+ preinstalled languages & tools, or install additional packages in your custom setup. Add safely encrypted configuration files and SSH keys. If it runs on Linux, it'll run on Semaphore too.
Use the latest Docker toolchain with privileged access to the Docker daemon. Run multi-container end-to-end tests in a fully virtualized environment. Learn more
Visualize your feedback loop. Understand how your builds evolve, and identify bottlenecks across your organization.
Got an unexpected build failure? Quickly reproduce and solve issues using SSH access to the Semaphore build environment.
“It’s really easy to scale with Semaphore compared to Jenkins, where a lot of maintenance and overhead is required. When we need more concurrency we just upgrade. Semaphore just works for us.”
Semaphore elevates cloud-based CI/CD to a whole new level of performance. Whatever you need to build, you'll get there faster than ever with fast processors, high-performance caching, automatic parallelism, and more.
Measured using the elixir-lang/elixir test suite.
Semaphore · 1m56s — 🎉 Winner!
Travis CI · 4m01s — 2.1x slower
CircleCI · 4m13s — 2.2x slower
Bare metal performance at the convenience of cloud. Each execution environment ("Box") is powered by an Intel Core i7 Skylark CPU, 8 GB DDR4 RAM and high-end I/O throughput.
Semaphore automatically caches project dependencies for all major languages, and supports Docker layer caching to reuse images across builds and deploys.
Waiting for tests for more than 10 minutes? Running them in parallel on Semaphore will save you a lot of valuable development time — and keep your team in a state of flow.
Even apps with 100k+ lines of code can now have a CI build that clocks at only a few minutes. It's as easy as dragging a slider. Learn more
“I’m a very happy manager right now. We had 45 minutes to more than an hour builds last week on Travis CI — on Semaphore we are usually under 10 minutes.”
Increase your team's focus on the product. Use Semaphore to eliminate DIY deployment procedures by integrating teams and processes with unified pipelines.
Use Semaphore's built-in integrations with AWS, Google cloud and Heroku to quickly set up deployment pipelines for the whole team. Or apply a script for custom deployment that you already use.
Build container images on Semaphore and push them to a registry for deployment. Integrations with Docker Hub, Amazon ECR, Google Container Registry and CoreOS Quay help you get there in just a few clicks.
Define different settings and environments for testing, staging, production, or any other environment. Deploy manually or continuously — whatever fits your team.
Get a clear-eyed view of your team's progress with a unified view of commits, test results and deploy history for every project.
“The feature I love the most is the deploy button — it deploys directly to production, and we don’t have to keep an eye on it every time. Before we switched to Semaphore, things could get pretty messy. We now continuously deploy a large application over 10 times a day.”
