The Verdict
Heap is built for product teams and growth marketers, with a focus on auto-capture and session-replay. Splunk targets enterprise and security teams and leads with log-analysis and real-time-monitoring.
Both tools use custom enterprise pricing — you'll need to contact sales for a quote, which makes direct cost comparison difficult.
Heap 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, Heap offers broader built-in capabilities (7 features vs 6), while Splunk 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.
