QueryFlow is a native macOS data engineering app that combines a SQL editor, Visual ETL pipeline builder, Python notebooks (Flow Books), and a local job scheduler in one Swift application.
Claude AI is integrated throughout with full schema awareness — when you connect a database, Claude sees every table, column, type, and relationship, so it writes valid SQL using your actual identifiers instead of hallucinating them.
Connects to Snowflake, Redshift, Postgres, MySQL, Salesforce, Google Sheets, and CSV as sources. Writes back to those same databases plus S3, SFTP, email, and Salesforce as destinations.
The Visual ETL builder uses drag-and-drop with AI-assisted field mapping. Flow Books combine SQL and Python cells with shared state. Scheduled jobs run locally via macOS SMAppService — no cron, no Lambda, no Airflow cluster required. Survives sleep/wake cycles and catches up missed runs on wake.
OAuth 2.0 authentication for Salesforce and Google Sheets means no security tokens to manage. Bulk API v2 handles large Salesforce operations automatically.
Available on the Mac App Store. 14-day free trial with no credit card required. Built by yforest LLC.
