The Verdict
CoStar is built for commercial brokers and property investors, with a focus on property-data and market-analytics. Heap targets product teams and growth teams and leads with auto-capture and retroactive-analytics.
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. CoStar requires a paid subscription from day one.
Feature-wise, CoStar offers broader built-in capabilities (7 features vs 6), while Heap 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.
