The Verdict
LinearB is built for engineering managers and vp engineering, with a focus on cycle-time-metrics and dora-metrics. 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 $39/mo for LinearB. That $29/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, LinearB offers broader built-in capabilities (7 features vs 6), while Semaphore takes a more focused approach — which can mean a simpler, faster onboarding experience.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
