It works entirely locally—no uploads or accounts—supports PostgreSQL, MySQL, SQLite, and SQL Server, and lets you drag tables, rename elements, and export to PNG or SVG.

ggsql extends SQL so you can write data queries and visualization specs in one composable syntax based on the Grammar of Graphics. It compiles to WebAssembly, works with DuckDB/SQLite and Vega-Lite, and offers an in-browser playground for immediate testing.

PgQue is a pure SQL/PLpgSQL event queue for Postgres 14+ that delivers durable, Kafka-style streams without dead tuples or external daemons. It uses snapshot-based batching and TRUNCATE-driven table rotation for stable performance under sustained load. A pg_cron (or any scheduler) ticker drives 1–2 second end-to-end delivery.

Rill’s Metrics SQL lets you define business metrics once and query them using plain SQL across dashboards, notebooks, and AI agents. It compiles metric views into optimized OLAP queries, handling grouping, filters, time functions, and security automatically.
