db-here: Local Directory-Isolated Databases
mayfer · x · 2026-07-15
A new npm package, db-here, has been released, focusing on "putting the database, along with its binaries, configs, and data, into a local folder".
Core Features
- Run directly via bunx db-here (currently supports mac / Linux)
- Automatically selects the right database binaries without requiring separate installation
- Database runs until ctrl+c is pressed, requiring no background daemon
- Simple default username/password for quick starts
- Backup/restore is as easy as copying the database directory
- AI agents can use it directly without touching system-level installations
- Supports pinned versions for easy app isolation
The author describes it as "worktrees for databases": multiple agents can use isolated databases across different workspaces in parallel, avoiding the need to spin up Docker just for isolation.
