QueryDen vs pgAdmin 4
pgAdmin is the official PostgreSQL administration tool, maintained by the PostgreSQL Global Development Group. It's a Python + web stack that runs a local web server and serves the UI to your browser. It is PostgreSQL-only and ships under the PostgreSQL license. QueryDen targets a multi-engine workflow with a native desktop UI instead of a browser-served local web app.

When pgAdmin 4 is the better choice
- You exclusively work with PostgreSQL and want the official tool maintained by the PG community.
- You need pgAdmin-specific admin features (e.g., backup/restore via pg_dump in the UI, full role/permission UIs).
- You're comfortable with the browser-served local web app model and don't mind the resource footprint.
When QueryDen is the better choice
- You work across more than just PostgreSQL — Supabase, MySQL, SQLite, CockroachDB all in one tool.
- You want a native desktop window, not a browser tab pointing at localhost.
- You prefer a ~11 MB installer to a ~200 MB Python + Flask install.
- You want machine-locked credential storage and an integrated AI assistant.
