From GitHub Actions to Semaphore: high performance, hands-on support, better pricing

GitHub Actions couldn’t keep up with our growing needs. Semaphore delivered faster builds, powerful parallelism, and hands-on support that helped us scale with confidence.

🚨 Before
⏳ Slow builds
🔁 Performance issues
💸 Cost inefficiencies
🛠️ Workflow friction

✅ After
⚡ 8-minute test suites
🚀 Massive parallelization
💰 Cost-optimized pipelines
🤝 Proactive support

✅ fast builds 8-minute test suites
✅ reduced costs

Why teams choose Semaphore over GitHub Actions

Built for performance at any scale ⚡

GitHub Actions may work for simple tasks—but once you need performance, scale, and real support, Semaphore takes over.

✔️ No limits on parallelism or job queues 
✔️ Scale pipelines without rewriting workflows 
✔️ Proactive support from CI/CD experts

📌 Spend less time fighting CI, more time shipping code.

“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.”

Amin Ben Slimen

Senior Software Engineer

Read case study

Faster builds, better dev experience 🚀

Semaphore is optimized for speed and clarity. Teams switching from GitHub Actions ship faster and spend less time debugging builds.

✔️ Optimized parallel test execution 
✔️ Workflow visibility and real-time debugging 
✔️ Predictable performance under load

📌 Keep your developers focused on product, not CI problems.

“It’s cheap, it’s easy to understand, and the support team is quick to assist if you need help. Honestly, after trying GitHub Actions, CircleCI, Octopus, Jenkins, and more, this clearly stands out to me as the better option.”

Fredrik August Madsen-Malmo

Head of DevOps at Kvist

One setup, multiple environments, total control 🌍

Avoid inconsistent setups across projects. Semaphore brings structure, flexibility, and control to teams working across any environment.

✔️ CI/CD as versioned code 
✔️ Runs across cloud, hybrid, and self-hosted 
✔️ Fine-grained permission control

📌 Consistent, scalable CI/CD for any team size.

“Semaphore is an incredibly easy-to-use CI/CD platform. Integrating my Ruby on Rails applications to use it is always very easy to do. Their platform has an incredibly good-looking UI, and documentation is also very well written.”

Lorenzo Zabot

Backend Engineer at Vox Group
