The Verdict
Amplitude is built for product teams and growth teams, with a focus on event-analytics and cohort-analysis. Splunk targets enterprise and security teams and leads with log-analysis and real-time-monitoring.
Splunk uses custom enterprise pricing, while Amplitude starts at $49/mo — a tangible advantage for teams with a fixed budget.
Amplitude has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Splunk requires a paid subscription from day one.
Feature-wise, Amplitude offers broader built-in capabilities (7 features vs 6), while Splunk takes a more focused approach — which can mean a simpler, faster onboarding experience.
Both tools are a solid fit for data analysts — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
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.
