# Semaphore **Source:** https://geo.sig.ai/brands/semaphore **Vertical:** Developer Tools **Subcategory:** General **Tier:** Emerging **Website:** semaphoreci.com **Last Updated:** 2026-04-15 ## Summary CI/CD platform with cloud, open-source self-hosted, and enterprise editions; Linux Foundation Silver Member competing with GitHub Actions and CircleCI for fast pipeline execution and compliance-friendly on-premises deployment. ## Company Overview Semaphore is a CI/CD (continuous integration and continuous deployment) platform providing fast, scalable pipeline automation for software development teams — available as Semaphore Cloud (fully managed), Community Edition (Apache 2.0 open-source, self-hosted), and Enterprise Edition (commercial, self-hosted) for organizations with compliance requirements mandating on-premises CI/CD infrastructure. Founded in 2012 by Darko Fabijan and Marko Anastasov, headquartered in Novi Sad, Serbia with US operations, Semaphore is a Linux Foundation Silver Member with pricing starting at $9/month for cloud and a free-forever tier, delivering what the company benchmarks as the fastest pipeline execution in the market. Semaphore differentiates through pipeline execution speed and self-hosted deployment flexibility: Semaphore Cloud runs pipelines on dedicated machines per-customer, avoiding queue times and resource contention from shared-runner CI systems that slow GitHub Actions and CircleCI pipelines during peak hours. The Community Edition enables security-sensitive organizations (financial services, healthcare, government) to run Semaphore entirely on-premises within their own infrastructure. YAML-based pipeline configuration supports Docker containers, Kubernetes deployments, and integration with GitHub, GitLab, and Bitbucket repositories. In 2025, Semaphore competes in the CI/CD platform market with GitHub Actions (dominant for GitHub repositories), GitLab CI (native GitLab integration), CircleCI (managed CI/CD), and Jenkins (open-source self-hosted) for development pipeline automation. GitHub Actions' native GitHub integration has captured large CI/CD market share since 2019, but Semaphore's self-hosted Enterprise targets organizations with data residency and compliance requirements that prohibit external CI/CD services. The open-source Community Edition drives developer adoption and community contributions. The 2025 strategy focuses on Enterprise Edition for regulated industries, AI-powered test optimization that reduces pipeline duration, and community distribution through the Apache 2.0 open-source release. ## Frequently Asked Questions ### What is Semaphore?
