Preen

Preen is a local-first, federated analytics engine built on top of DuckDB. Think of Preen as an open-core version of Fivetran, Hightouch, or Stitch for local data processing. Preen enables accessing data across 10s, 100s or 1000s of data sources. The only thing you need is a laptop, basic SQL and access to your data sources.

Why Preen?

• Run analysis and train AI models directly from the primary copy of your company's data.
• Build data applications with their own local database, think SQLite for data applications.
• No datalakes. No cloud computing. No copies of data that create numerous conflicting versions of data.
• Get instant access to exactly the data you need without waiting on another team.
• Describe your Company's data universe in code. Build ephemeral, versioned, enterprise data warehouses from scratch directly on your laptop.
