Quick Selection Guide
Data Hub
Best for: Your primary onchain data warehouse, analytic workflows, and data transformationsFull SQL access with 100+ chains, flexible schemas, and compute-based pricing
Datashare
Best for: Data warehouse integration and interoperabilityDirect access via Snowflake, BigQuery, or Databricks with full historical data
Sim (Realtime APIs)
Best for: Building realtime wallets, portfolio trackers, and DeFi applicationsSub-second response times with 60+ chains via REST APIs
Catalyst
Best for: Blockchain integration and data infrastructureDune’s toolkit for chains and protocols to get indexed and make their data accessible
Why is Catalyst not in the comparison tables? Catalyst is Dune’s blockchain integration toolkit designed for chains and protocols, not end-user data consumption. It powers how blockchains get indexed into Dune rather than how users query data, so it serves a fundamentally different purpose than Data Hub, Datashare, and Sim (Realtime APIs).
