The Verdict
LinearB is built for engineering managers and vp engineering, with a focus on cycle-time-metrics and dora-metrics. SpyFu targets ppc managers and seo professionals and leads with competitor-keywords and ppc-research.
Both tools come in at similar price points ($39/mo for LinearB, $39/mo for SpyFu), so pricing won't make the decision for you.
LinearB has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. SpyFu requires a paid subscription from day one.
Feature-wise, LinearB offers broader built-in capabilities (7 features vs 6), while SpyFu 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.
