The Verdict
CoStar is built for commercial brokers and property investors, with a focus on property-data and market-analytics. 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.
Neither tool offers a free plan, so factor the subscription cost into your decision from the start.
Feature-wise, CoStar 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.
