Datapuddle is a native macOS client for DuckDB that renders query results without paging, reading directly from columnar chunks to keep memory flat even for tens of millions of rows. It adds column profiling, query plan visualization, a DuckDB-aware SQL editor, and Keychain-backed connections. It's interesting for its performance-first design and polished native UX, though it's a commercial product rather than open source.

Target audience: data analysts, data engineers, developers working with local analytics
