The Verdict
Buffer is built for solopreneurs and small businesses, with a focus on scheduling and analytics. CoStar targets commercial brokers and property investors and leads with property-data and market-analytics.
CoStar uses custom enterprise pricing, while Buffer starts at $6/mo — a tangible advantage for teams with a fixed budget.
Buffer 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.
Buffer edges out on user ratings (4.4 vs 4.1). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Bottom line: Buffer has a slight overall edge — but if most comprehensive commercial real estate database matters most to you, CoStar may still be the right call.
