The Verdict
Grafana is built for devops teams and sre teams, with a focus on dashboards and data-sources. Semaphore targets development teams and open source projects and leads with parallel-pipelines and test-reports.
On pricing, Semaphore is the clear winner for budget-conscious users — starting at $10/mo compared to $29/mo for Grafana. That $19/mo difference adds up quickly for growing teams.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Grafana offers broader built-in capabilities (8 features vs 6), while Semaphore takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Grafana has a slight overall edge — but if extremely fast build times matters most to you, Semaphore may still be the right call.
