# PGXN Client > `pgxnclient` does not normally ship with PostgreSQL, so you will probably have to install it manually. The [PGXN Client](https://pgxn.github.io/pgxnclient/) is a command line tool designed to interact with the [PostgreSQL Extension Network](https://pgxn.org/) allowing searching, compiling, installing, and removing extensions in PostgreSQL databases. ## Ubuntu On Ubuntu you can install using `apt` ```bash apt-get install pgxnclient ``` ## MacOS On MacOs you can install using `brew` ```bash brew install pgxnclient ```
