Open source Postgres GUI
A native Mac PostgreSQL client you can inspect, build, and use.
PostgresGUI is an open source Postgres GUI for Mac. Build it from source for free, or use the signed Mac App Store version to support ongoing development with a one-time purchase.
No subscription
Use a one-time App Store purchase for signed builds and automatic updates.
Postgres-focused
Skip broad multi-database complexity when your daily work is PostgreSQL.
Free source, paid signed builds
If you want a free Postgres client for Mac and are comfortable building from source, the repository is public. If you want a notarized app with normal Mac App Store installation and updates, the paid version keeps the project sustainable.
