VERDICT

Should I use Semaphore?

Semaphore CI built for coding agents - fast, affordable, and enterprise-ready. - semaphore.io

Depends. Worth trialing if you need fast hosted CI with agent-friendly usage pricing and have outgrown GitHub Actions. Skip if you already run GitHub Actions or GitLab CI — and note the evidence here is thin.

Confidence

Low. Based on 10 public sources; many snippets truncated and several cover similarly named products (Semaphore UI, Progress Semaphore), so confidence is low.
