VERDICT

Should I use Semaphore?

Semaphore CI built for coding agents - fast, affordable, and enterprise-ready. - semaphoreci.com

Depends. Reasonable buy for GitHub-based teams running heavy pipelines that want aggressive usage-based pricing. Skip if you expect free self-hosted runners or need a deep independent review track record before committing.

Confidence

Medium. Based on ~10 usable public sources. Many 'Semaphore' search results refer to unrelated products (Ansible Semaphore UI, Progress Semaphore, a crypto protocol) and were excluded; CVEs found apply to Semaphore UI, not this product.
