Overview

Semaphore is a cloud-native CI/CD platform founded in 2012 by Darko Fabijan and Marko Anastasov and headquartered in Novi Sad, Serbia. Operated by Semaphore Technologies doo, it offers fully managed cloud, hybrid, and self-hosted deployment options. The platform is designed to maximize build speed and pipeline reliability, running on optimized bare-metal infrastructure. In February 2025, Semaphore open-sourced its core platform under Apache 2.0, adding a free Community Edition alongside its Cloud and Enterprise offerings. It serves over 300,000 organizations globally—from startups to Fortune 500 companies—and is certified SOC 2 and ISO 27001. Key differentiators include raw build performance, pay-per-second compute pricing, flaky test detection, and AI-driven pipeline analysis.

Semaphore is an AI-driven CI/CD platform offering fast, reliable pipeline execution across cloud, hybrid, and self-hosted environments. It provides a visual pipeline editor, parallel job execution, flaky test detection, deployment automations with approval gates, and deep observability—all under a pay-per-second compute model. Its 2025 open-source release makes the core platform available for self-hosting without cost.
