The Verdict
CoStar is built for commercial brokers and property investors, with a focus on property-data and market-analytics. Microsoft Clarity targets small businesses and startups and leads with session-recordings and heatmaps.
Both tools use custom enterprise pricing — you'll need to contact sales for a quote, which makes direct cost comparison difficult.
Microsoft Clarity 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.
Microsoft Clarity edges out on user ratings (4.5 vs 4.1). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Bottom line: Microsoft Clarity has a slight overall edge — but if most comprehensive commercial real estate database matters most to you, CoStar may still be the right call.
