The Verdict
Datadog is built for devops teams and sre teams, with a focus on infrastructure-monitoring and apm. SpyFu targets ppc managers and seo professionals and leads with competitor-keywords and ppc-research.
On pricing, Datadog is the clear winner for budget-conscious users — starting at $15/mo compared to $39/mo for SpyFu. That $24/mo difference adds up quickly for growing teams.
Datadog 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, Datadog offers broader built-in capabilities (8 features vs 6), while SpyFu takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Datadog has a slight overall edge — but if unlimited search results on all plans matters most to you, SpyFu may still be the right call.
