ETL / ELT / Reverse ETL Framework powered by DuckDB, designed to seamlessly integrate and process data from diverse sources. It leverages Markdown as a configuration medium, where YAML blocks define metadata for each data source, and embedded SQL blocks specify the extraction, transformation, and loading logic.
Go SDK for the VGI (Vector Gateway Interface) protocol — host DuckDB scalar, table, aggregate, and table-in-out functions in an external worker over Arrow IPC.
🦦 Pandas-style DataFrame library for Go — fluent API for filtering, grouping, sorting, and statistical analysis with type-safe operations and zero-copy typed slice access.
Lightweight self-hosted workflow scheduler in a single Go binary — an open-source Airflow/Azkaban alternative. Embedded SQLite, DAGs (cron + dependencies + backfill), polyglot tasks (shell/Python/SQL/JAR/HTTP), web console, REST API, and a built-in MCP server for AI agents. Linux & macOS.
