About NexQL
NexQL is a VS Code extension that integrates PostgreSQL workflows into the editor environment. It allows users to connect to PostgreSQL databases, inspect schemas, execute SQL notebooks, and analyze query performance without leaving the IDE. The tool supports schema exploration across 16+ object types, live query execution with results visualization, and AI-assisted SQL generation using schema context. It includes features for query optimization with EXPLAIN analysis and index recommendations, as well as schema design tools with ERD visualization and diff viewers. Environment safety features label connections as DEV, STAGE, or PROD to prevent accidental changes to production systems. Team collaboration is supported through shared SQL notebooks and encrypted cloud sync of connection profiles and context.
