The Verdict
Semaphore is built for development teams and open source projects, with a focus on parallel-pipelines and test-reports. Tray.io targets enterprises and revenue operations and leads with visual-workflow-builder and api-connectors.
Tray.io uses custom enterprise pricing, while Semaphore starts at $10/mo — a tangible advantage for teams with a fixed budget.
Semaphore has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Tray.io requires a paid subscription from day one.
