Postico is available only for the Mac.
Postico 2 requires macOS 10.15 (Catalina) or newer.
Postico is a universal binary. It contains native code for both Macs with Intel processors (x86_64) and Macs with Apple Silicon (arm64).
If you have an older Mac, please see the page about old versions of Postico.
Postico supports connecting to the following databases:
We run automated tests against multiple versions of these databases to ensure compatibility.
Postico may also be able to connect to some databases that are compatible with the PostgreSQL wire protocol (eg. Vertica) and execute queries, but due to completely different catalog tables most features will not work.
