# JetBrains Gateway

JetBrains Gateway is a compact desktop app that allows you to work remotely with a JetBrains IDE without even downloading one. [See JetBrains' website to learn about and Gateway.](https://www.jetbrains.com/remote-development/gateway/)

Gateway can connect to a Coder workspace by using Coder's Gateway plugin or manually setting up an SSH connection.
