Six engines, one client
PostgreSQL, MySQL/MariaDB, SQL Server, SQLite, MongoDB and Redis run on the same core, the same grid and the same guards. A driver is only called supported once it passes the conformance kit against a real server.
Browse and edit your data in a grid, or write a query. Both are first-class, and you never leave the editor.

Guide — installing, connecting, the grid, query mode, the safety guards, and what changes when VS Code is running against a remote machine.
Recipes — a working connection for Docker, RDS, Cloud SQL, Azure, Supabase, Neon, an SSH bastion, Atlas, Redis Cluster, and SQLite, including the setting each provider gets wrong by default.
Writing a driver — adding an engine is a new package and no edit to core. CI enforces that, and this guide is what it enforces against.
Design record — the specification, the architecture, the driver contract, the security requirements and every architecture decision, published because a contributor needs the reasoning more than the summary.
