The Verdict
Heap is built for product teams and growth marketers, with a focus on auto-capture and session-replay. Semrush targets digital marketers and agencies and leads with keyword-research and site-audit.
Heap uses custom enterprise pricing, while Semrush starts at $139.95/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Bottom line: Semrush has a slight overall edge — but if auto-captures all user interactions without code matters most to you, Heap may still be the right call.
